Why Sakuli?

There are already a variety of free end2end/automation tools on the market (Sahi, Selenium, WebInject, Sikuli, CasperJS, AutoIT , …), but each of them has at least one of the following drawbacks:

  • Too specifically: pure web testing tools can only deal with pure web content. Applets, Flash, dialogues generated by OS, browser dialogues etc. are invisible and a insurmountable hurdle for such tools.

  • Too generic: screen-based testing tools "see" everything the user sees. They are the best choice for GUI tests, but inappropriate for web tests, because each browser type has its own understanding of how to render and display a web page.

  • Far from reality: There are tools to test web applications on protocol level - but to know whether a web application is working or not requires a test from the user’s perspective.

  • Inflexible: Hardly one of these tools brings the ability to integrate into other systems (like Nagios or Jenkins).

Key Features

  • Platform-independent UI testing tool

  • End-2-End monitoring of application functionality and quality

  • Combines two automation technologies:

    • DOM based web testing

    • Image pattern based UI automation (for non-web content)

  • Scalable from single-client up to multi-node container setup for parallel execution

  • Integration of test results into

    • Monitoring systems (e.g. Nagios/Icinga)

    • CI builds (e.g. Jenkins)

Concept

sakuli concept

Sakuli simulates user actions on graphical user interfaces (web, fat client, citrix, …), and provides the obtained information (runtime, result, screenshots) to third party (e.g. Nagios compatible monitoring) systems.

Sakuli is written in Java and runs on many platforms:

The Sakuli project brings together two Open-Source end-to-end testing tools which perfectly fit together: Sahi for web-based tests (by injecting JavaScript code into the browser), as well as the screenshot-based testing tool Sikuli, which allows the execution of keyboard and mouse actions on screen areas that have been defined by previously recorded screenshots and are recognized using the OpenCV engine.

Sakuli accesses both tools via its Java API and makes it possible to use them simultaneously. For example, web tests can be done very performant with Sahi (where a screenshot-based approach would be at best the second choice), whereas "off-DOM"-content can be catched with Sikuli. Whenever a web test comes into a situation which Sahi can’t handle (e.g. a PIN dialogue for a smartcard login), use a Sikuli command. On the other hand, pure tests of fat client applications can be easily be setup by using only the Sikuli functions of Sakuli.

Components of Sakuli

1.2.1. Native Execution

1.2.1.1. Windows Client
Installation

This page describes the steps to install and test Sakuli on Windows. If you want to update Sakuli, see the Upgrade process documentation.

The default installation path of a particular Sakuli version is referenced as %SAKULI_HOME% (also called the "version" folder) which is inside of the folder "sakuli":

> echo %SAKULI_HOME%
  C:\Program Files (x86)\sakuli\sakuli-v1.1.0-SNAPSHOT

Values surrounded by double underscores are have to be filled individually by you (e.g. IP_ADDRESS).

Machine requirements

You can run Sakuli on physical as well as on virtual Linux machines.

  • OS: Microsoft Windows (version 7 and higher)

  • 64 Bit (recommended)

  • RAM: 2GB or more

  • CPU: at least two CPU cores

  • Software:

  • Java JRE >= 1.8

Recommendations
  • Set the desktop background to a homogenous color.

  • disable any screen locking mechanisms

  • Run Sakuli with a dedicated user

  • Sakuli needs a reliable and predictable desktop environment: make sure that there are no pop-up windows of services or applications

  • If Sakuli is running within a VM, change the desktop resolution to a fixed value (e.g. 1024x768) and disable any auto-resizing mechanisms of the guest display. This ensures that the guest’s resolution does not change in case that you resize its window.

  • the client should not have more than one physical screen

Sakuli installation
  • Download the Sakuli Installer from http://labs.consol.de/sakuli/install

  • current development snapshot = sakuli-vX.X.X-SNAPSHOT-installer.jar

  • current stable version = sakuli-vX.X.X-installer.jar (recommended)

Double-click on the downloaded .jar file to start the installer:

inst_1

Read and accept the licence, choose the installation folder (any path the current user has rw permissions is ok) and select the packages to install:

inst_2

  1. install Sakuli

  2. install Sahi

  3. set/update the environment variable %SAKULI_HOME% to the new version.

  4. set/update environment settings which have proved as best practice for UI tests.

  5. install one example test suite per OS which help you to test and understand Sakuli.

  6. install Firefox Portable, which can be used exclusively for Sakuli Tests.

  7. install QRes, a open source screen mode changer (Windows only)

In the end you are offered to generate a headless installation file which can be executed on other hosts with:

java -jar sakuli-vX.X.X-installer.jar auto-config.xml

Reboot now to take the registry changes effect.

Test

Now test if Sahi can start a Sahi-controlled browser.

Execute %SAKULI_HOME%\sahi\userdata\bin\start_dashboard.bat to open the Sahi Dashboard. It should now list all available browsers on this system.

dashboards

Click on any browser icon: it should start and present you the start page of Sahi:

sahi_start

At last, test the Sahi Controller by holding the ALT key and double-clicking on any white space on the page. If you are getting a new window showing the "Sahi Controller", you’re done. Close all browser windows and Sahi.

controller_windows

You are now ready to run the first minimal Sakuli test to see if Sakuli and its components are working well together. Open a new terminal to start a test:

  • Windows 7: sakuli run INST_DIR\example_test_suites\example_windows7\

  • Windows 8: sakuli run INST_DIR\example_test_suites\example_windows8\

Sakuli should now

  1. open Firefox with the Sakuli welcome page, highlight some page elements

  2. open the calculator and calculate 525+100=625

  3. open an editor and write a status message

Additional documentation:
Optional software
PhantomJS

Currently, each Sakuli test requires to start a browser, which is not very handy for pure Sikuli GUI tests (=where no browser at all is needed). For that case, use a headless browser like PhantomJS. Refer to Browser configuration for more information.

Attention: PhantomJS 2 is currently unsupported. Use version 1.9.x

Screenshot tool

Use a screenshot tool which is able to

  • capture areas of the screen

  • delay the creation of screenshots for x seconds (important if Sikuli must navigate through menues)

A good choice is

Always make sure that screenshots are saved without compression. Sikuli uses a default similarity of 0.99, which internally means that "more than 99%" => 100% pixels must conincide. Decreasing similarity should only be neccessary if the pattern images are of poor quality or the region compared to always slightly differs from the pattern image.

Editor

It is recommended to use an Editor with JavaScript support, e. g. Notepad++

It also possible to use professional programming IDEs like IntelliJ, Netbeans or Eclipse.

Next steps
RDP peculiarities
Things to know

There are four ways to connect to and work on a Sakuli client machine:

  1. VNC

  2. Console of a virtualization platform (ESX, Virtualbox, etc.)

  3. Remote Desktop (Windows)

  4. local screen

For case 1. and 2. there is nothing special to watch out for, except that the screen must not be locked (otherwise Sikuli will also see a locked screen). The screen content will be the same as displays on a local screen (4.).

For RDP on Windows there are some special things to know. Connecting to the Sakuli test client via RDP locks any existing local console session of that user and attaches (="moves") it to a RDP session.

Sakuli will just as well run within that RDP session. But closing/disconnecting/logging of that RDP session will not unlock the local console session again. Sakuli will see the same as a regular user: nothing but a locked screen. Read the next paragraph to learn how to avoid this.

LOGOFF.bat

To log off a RDP session, right-click %SAKULI_HOME%\bin\helper\LOGOFF.bat and execute the script with administrator privileges. The script then

  • determines the current RDP session ID

  • redirects this session back to the local console

  • terminates the RDP session.

check_logon_session.ps1

In %SAKULI_HOME%\setup\nagios you can find check_logon_session.ps1 which can be used as a client-side Nagios check to ensure that the Sakuli user is always logged on, either via RDP or on the local console. Instructions for the implementation of this check can be found in the script header.

Define a service dependency of all Sakuli checks to this logon check; this will ensure that a locked session will not raise false alarms.

user-login

Troubleshooting

If you have some errors with your Windows installation, you can check the following points:

Change Windows theme and title bar colors

Windows 7 comes by default with an "aero" theme, which is quite awkward for Sikuli, because there are many transparency effects which cause window elements to change their appearance dependend on the elements below. For that, change the theme to "Windows Classic".

classic

Furthermore, change the colors of active and inactive title bars to non gradient: titlebars

RDP related settings

The following steps have only to be done if you are accessing the Sakuli Client via RDP.

Disable Clipboard Sharing

The "paste" function of Sakuli uses the clipboard at runtime to decrypt and paste passwords. For this reason, the clipboard exchange of the Sakuli client and the RDP client should be suppressed in the settings tab of your local Remote Desktop client:

clipboard

This can be set globally in the registry of your local host:

  1. regedit

  2. [ HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client ]

  3. DisableDriveRedirection (DWORD) => 1

Disable the "GUI-less" mode

If you minimize the Remote Desktop window (the window that display the remote computer’s desktop), the operating system switches the remote session to a "GUI-less mode" which does not transfer any window data anymore. As a result, Sakuli is unable to interact with the tested application’s GUI, as the whole screen is not visible.

To disable the "GUI-less" mode on your local host:

  1. regedit

  2. [ HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client ]

  3. RemoteDesktop_SuppressWhenMinimized (DWORD) => 2

1.2.1.2. Linux Client
Installation

This page describes the steps to install and test Sakuli on Ubuntu Linux 16.04 LTS. For other distributions (CentOS, OpenSuSE, …​) they be mostly identical. If you want to update Sakuli, see the Upgrade process documentation.

The default installation path of a particular Sakuli version is referenced as $SAKULI_HOME (also called the "version" folder) which is inside of the folder "sakuli":

> echo $SAKULI_HOME
  /opt/sakuli/sakuli-v1.1.0-SNAPSHOT

Values surrounded by double underscores are have to be filled individually by you (e.g. IP_ADDRESS).

Machine requirements

You can run Sakuli on physical as well as on virtual Linux machines.

  • Linux OS (here: Ubuntu 16.04 LTS Desktop)

  • 64 Bit (recommended)

  • RAM: 2GB or more

  • CPU: at least two CPU cores

Software requirements

sudo apt-get install openjdk-8-jre tesseract-ocr wmctrl xdotool

Recommendations
  • Set the desktop background to a homogenous color.

  • disable any screen locking mechanisms

  • Run Sakuli with a dedicated user

  • Sakuli needs a reliable and predictable desktop environment: make sure that there are no pop-up windows of services or applications

  • If Sakuli is running within a VM, change the desktop resolution to a fixed value (e.g. 1024x768) and disable any auto-resizing mechanisms of the guest display. This ensures that the guest’s resolution does not change in case that you resize its window.

  • Other optional steps see Install GNOME session fallback theme.

  • the client should not have more than one physical screen

Sakuli installation
  • Download the Sakuli Installer from http://labs.consol.de/sakuli/install

  • current development snapshot = sakuli-vX.X.X-SNAPSHOT-installer.jar

  • current stable version = sakuli-vX.X.X-installer.jar (recommended)

Execute java -jar sakuli-vX.X.X-installer.jar to start the installer:

inst_1

Read and accept the licence, choose the installation folder (any path the current user has rw permissions is ok) and select the packages to install:

inst_2

  1. install Sakuli

  2. install Sahi

  3. set/update the environment variable $SAKULI_HOME which points to the new version.

  4. set/update .bashrc

  5. install one example test suite per OS which help you to test and understand Sakuli.

  6. install Firefox Portable, which can be used exclusively for Sakuli Tests

In the end you are offered to generate a headless installation file which can be executed on other hosts with:

java -jar sakuli-vX.X.X-installer.jar auto-config.xml
Test

Now test if Sahi can start a Sahi-controlled browser.

Execute $SAKULI_HOME/sahi/userdata/bin/start_dashboard.sh to open the Sahi Dashboard. It should now list all available browsers on this system.

dashboards

Click on any browser icon, it should start and present you the start page of Sahi:

sahi_start

At last, test the Sahi Controller by holding the ALT key and double-clicking on any white space on the page. If you are getting a new window showing the "Sahi Controller", you’re done. Close all browser windows and Sahi.

controller_linux

On Linux deskops the ALT key is often predefined to drag windows. In this case, open $SAKULI_HOME/sahi/config/sahi.properties and change the "hotkey" property:
controller.hotkey=SHIFT

You are now ready to run the first minimal Sakuli test to see if Sakuli and its components are working well together. Open a new terminal to start a test:

sakuli run __INST_DIR__/example_test_suites/example_ubuntu/

Sakuli should now

  1. open Firefox with the Sakuli welcome page, highlight some page elements

  2. open the calculator and calculate 525+100=625

  3. open an editor and write a status message

Attention: PhantomJS 2 is currently unsupported. Use version 1.9.x

Screenshot tool

Use a screenshot tool which is able to

  • capture areas of the screen

  • delay the creation of screenshots for x seconds (important if Sikuli must navigate through menues)

A good choice is

  • Shutter on Linux.

  • Scrot on Linux (lightweight, cli-based).

Always make sure that screenshots are saved without compression. Sikuli uses a default similarity of 0.99, which internally means that "more than 99%" => 100% pixels must conincide. Decreasing similarity should only be neccessary if the pattern images are of poor quality or the region compared to always slightly differs from the pattern image.

Editor

It is recommended to use an Editor with JavaScript support, e.g. Atom

It also possible to use professional programming IDEs like IntelliJ, Netbeans or Eclipse.

Next steps
Headless checks

Running Sakuli on the user desktop is nice, but has the drawback that the session gets highjacked on each Sakuli run. Moving the mouse e.g. can have negative effects on the test execution.

For that reason we advise to run Linux based Sakuli checks in in one of the following modes:

  • in a virtual display (="headless"), which is straightforward in Linux (documented on this page)

  • in Docker containers (more scalable)

Installing and configuring the VNC server

On Ubuntu, first install vnc4server:

sudo apt-get install vnc4server

Start vncserver for the first time to create a session password:

~$ vncserver

You will require a password to access your desktops.
Password:
Verify:

New 'sakulidemo:1 (sakuli)' desktop is sakulidemo:1

Creating default startup script __HOME__/.vnc/xstartup
Starting applications specified in __HOME__/.vnc/xstartup
Log file is __HOME__/.vnc/sakulidemo:1.log

.vnc/xstartup controls what to start within a xvnc session. Do not touch this file on OpenSUSE; on Ubuntu you have to replace its content with the following lines (because you are using gnome-session-fallback, aren’t you…?):

~$ vim .vnc/xstartup

#!/bin/sh
export XKL_XMODMAP_DISABLE=1
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS

gnome-panel &
gnome-settings-daemon &
metacity &

Restart the current vnc sesssion:

~$ vncserver -kill :1 && vncserver

Now open a RDP client (on Ubuntu: Applications - Internet - Remmina Remote Desktop Client) and enter the connection data:

  • Protocol: VNC

  • Server: localhost:5901

  • Password: VNC_SESSION_PASSWORD

You should see now an empty GNOME/KDE desktop - started headless!

Test

You are now ready to run the minimal Sakuli check in headless (=VNC) mode. Sakuli provides for this task a pre- and postHook script, which can be used like follow:

On the Ubuntu desktop, open a terminal window and execute

  • on Ubuntu: sakuli run INST_DIR/example_test_suites/example_ubuntu/ --vnc

  • on openSUSE: SAKULI_HOME/bin/sakuli.sh --run INST_DIR/example_test_suites/example_opensuse/ --vnc

You should see that Sakuli

  1. opens Firefox

  2. opens the calculator and calculates 525+100=625

  3. opens an editor and writes a status message

vnc test example

Scheduling by cron

Add the following line to Sakuli’s crontab:

SAKULI_HOME=__SAKULI_HOME__
DISPLAY=:1

*/2 * * * * $SAKULI_HOME/bin/sakuli run $SAKULI_HOME/../example_test_suites/example_ubuntu -preHook $SAKULI_HOME/bin/helper/vnc.sh -postHook '$SAKULI_HOME/bin/helper/vnc.sh -kill' 2>&1 > /dev/null
Troubleshooting

If you have some errors with your Linux installation, you can check the following points:

Install GNOME session fallback theme

Sakuli can test on Unity, of course - but gnome-session-fallback is more than sufficient…

sudo apt-get install gnome-session-fallback

After the installation, relogin and select the desktop environment GNOME Flashback (Metacity):

fallback

flashback

The Ubuntu menu bar should have changed now to the "classical" one:

menu

Restore gsettings key bindings

In headless checks you will encounter problems using the TAB key as well as s:

  • The TAB key will switch applications (like ALT + TAB)

  • s will open the applications menu

For some reason (?), gsettings binds s and TAB to the Super key by default. Open a terminal as the Sakuli user and execute the following commands to restore that to the default:

gsettings set org.gnome.desktop.wm.keybindings switch-applications "['<Alt>Tab']"
gsettings set org.gnome.desktop.wm.keybindings panel-main-menu "['<Alt>F1']"
1.2.1.3. Upgrade process

Before you upgrade your current Sakuli installation, please ensure that you have read the Change Log.

Execute SAKULI_HOME/../Uninstaller/uninstaller.jar to remove the current installed version. This will only affect the files in SAKULI_HOME. The uninstaller removes all installed files, and resets the environment configuration.

After that just install the new version.

1.2.2. Maven Execution

1.2.2.1. Sakuli Java DSL

Sakuli provides a Java DSL for writing test cases in pure Java. The DSL is designed as fluent API and provides the exact same capabilities as the Javascript API. The Sakuli Java API enables users to write Sakuli tests in pure Java unit tests using JUnit or TestNG. The good news about that is that you are able to access any native application UI with screen related actions as easy as in JavaScript API.

Usage

The Sakuli Java DSL comes to you as Maven module JAR file. You can add the module to your Sakuli project as Maven dependency. Currently the Java tests have to be written with the TestNG unit framework, so also provide the TestNG Maven dependency in your project POM:

    <dependencies>
        <dependency>
            <groupId>org.sakuli</groupId>
            <artifactId>java-dsl</artifactId>
            <version>${sakuli.version}</version>
            <scope>test</scope>
        </dependency>
        <!-- needed for AbstractSakuliTest class -->
        <dependency>
            <groupId>org.sakuli</groupId>
            <artifactId>java-dsl</artifactId>
            <version>${sakuli.version}</version>
            <type>test-jar</type>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.testng</groupId>
            <artifactId>testng</artifactId>
            <version>${testng.version}</version>
            <scope>test</scope>
        </dependency>
    </dependencies>

In the last step, we have to provide also some local resources for our Sakuli test setup. Therefore we use the maven-dependency-plugin to unpack all needed Sakuli resources to our local project.build.outputDirectory:

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-dependency-plugin</artifactId>
                <executions>
                    <execution>
                        <id>unpack</id>
                        <phase>generate-resources</phase>
                        <goals>
                            <goal>unpack</goal>
                        </goals>
                        <configuration>
                            <artifactItems>
                                <artifactItem>
                                    <groupId>org.sakuli</groupId>
                                    <artifactId>java-dsl</artifactId>
                                    <version>${sakuli.version}</version>
                                    <type>jar</type>
                                    <overWrite>true</overWrite>
                                </artifactItem>
                            </artifactItems>
                            <outputDirectory>${project.build.outputDirectory}</outputDirectory>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

Now we are ready to write Java tests. See the following sample test which uses TestNG unit testing library in combination with Sakuli Java DSL:

        public class FirstExampleTest extends AbstractSakuliTest {

            Environment env;

            @BeforeClass
            @Override
            public void initTC() throws Exception {
                super.initTC();
                env = new Environment();
            }

            @Override
            protected TestCaseInitParameter getTestCaseInitParameter() throws Exception {
                return new TestCaseInitParameter("test1");
            }

            @Test
            public void testCitrus() throws Exception {
                browser.open();
                browser.navigateTo("http://www.citrusframework.org/");

                ElementStub heading1 = browser.paragraph("Citrus Integration Testing");
                heading1.highlight();
                assertTrue(heading1.isVisible());

                ElementStub download = browser.link("/Download v.*/");
                download.highlight();
                assertTrue(download.isVisible());
                download.click();

                ElementStub downloadLink = browser.cell("2.6.1");
                downloadLink.highlight();
                assertTrue(downloadLink.isVisible());
            }
        }

All people that are familiar with TestNG unit testing will notice that a Sakuli Java test is nothing but a normal TestNG unit test. Sakuli just adds the end-to-end testing capabilities. The test class extends an abstract class coming from Sakuli. This AbstractSakuliTest provides convenient access to the Sakuli Java DSL API.

These are methods such as initTC() and getTestCaseInitParameter() that are customizable in test classes. Just overwrite the methods and add custom logic. In addition to that the abstract super class in Sakuli provides access to the browser field that represents the Sahi web browser capabilities. This browser object is used in the test cases to trigger Sahi related actions such as opening a website and highlighting links or buttons.

In the example above we open a website http://www.citrusframework.org/ and assert the content on that page. In the example above we open a website http://www.citrusframework.org/ and assert the content on that page.

Now lets add some testing logic that works with content other than HTML dom related content. We add a test step that puts focus to the web browser task bar. In detail we click into the browser search input field, fill in a word and perform the search.

        new Region().find("search").click().type("Citrus");
        env.sleep(1);
        new Region().takeScreenshot("test.png");

The region object provides access to Sakuli screen related actions such as finding a component on the screen. We can click that region and fill in some characters (e.g. in the search input field). After that we sleep some time to give the search operation some time to perform its actions. As a last step we take a screenshot of the result page and the test is finished.

This little example demonstrates the basic usage of the Sakuli Java API. We write normal Java unit tests with TestNG and add Sakuli specific actions on HTML dom content in a browser or any native application operations by screen related access.

Next we will setup a complete sample project for Sakuli Java.

Sakuli Java Example

The next section describes how to get started with the Sakuli Java DSL by example. The Java example is a fully runnable Java sample test case. So at the end of this chapter you should be able to start writing Sakuli test in pure Java.

An example how to use Java DSL and setup Maven you will find at: github.com/ConSol/sakuli-examples

Installation
Preparation
  1. Install Java Development Kit version 8.

  2. Install Maven (Version 3.2.5 or higher).

  3. Download java-example directory from github.com/ConSol/sakuli-examples.

Project setup and compilation
  1. Import java-example to IDE (IntelliJ or Eclipse…) as Maven project: Example for IntelliJ:

  2. Choose Project from Existing Sources…​ in File menu.

  3. Choose pom.xml and click next button till the project is imported.

Try to compile the new Sakuli Maven project. If an ERROR is reported please check your pom.xml first. The following section has to be present in your Maven POM:

<repository>
    <id>labs-consol-snapshots</id>
    <name>ConSol* Labs Repository</name>
    <url>http://labs.consol.de/maven/snapshots-repository</url>
    <snapshots>
        <enabled>true</enabled>
    </snapshots>
    <releases>
        <enabled>false</enabled>
    </releases>
</repository>

The ConSol labs Maven repository should be placed to the repositories section in your POM. After this is done please execute the Maven compile phase.

Test execute

Once compilation has been SUCCESS try to execute test phase as a next step.

Configuration

For customized browser detection create your own browser_types.xml file. This file should be located in main/resources/sahi/userdata/config package in src folder. The content of this file looks like follows:

    <browserTypes>
        <browserType>
            <name>firefox</name>
            <displayName>Firefox</displayName>
            <icon>firefox.png</icon>
            <path>$ProgramFiles (x86)\Mozilla Firefox\firefox.exe</path>
            <options>-profile "$userDir/browser/ff/profiles/sahi$threadNo" -no-remote</options>
            <processName>firefox.exe</processName>
            <capacity>5</capacity>
        </browserType>

        <browserType>
            <name>ie</name>
            <displayName>IE</displayName>
            <icon>ie.png</icon>
            <path>$ProgramFiles\Internet Explorer\iexplore.exe</path>

            <processName>iexplore.exe</processName>
            <useSystemProxy>true</useSystemProxy>
            <capacity>5</capacity>
        </browserType>

        <browserType>
            <name>chrome</name>
            <displayName>Chrome</displayName>
            <icon>chrome.png</icon>
            <path>C:\Program Files (x86)\Google\Chrome\Application\chrome.exe</path>
            <options>--incognito --user-data-dir=$userDir\browser\chrome\profiles\sahi$threadNo --proxy-server=localhost:9999 --disable-popup-blocking</options>
            <processName>chrome.exe</processName>
            <capacity>5</capacity>
        </browserType>

        <browserType>
            <name>safari</name>
            <displayName>Safari</displayName>
            <icon>safari.png</icon>
            <path>$ProgramFiles (x86)\Safari\Safari.exe</path>
            <options> </options>
            <processName>safari.exe</processName>
            <useSystemProxy>true</useSystemProxy>
            <capacity>1</capacity>
        </browserType>

        <browserType>
            <name>opera</name>
            <displayName>Opera</displayName>
            <icon>opera.png</icon>
            <path>$ProgramFiles (x86)\Opera\opera.exe</path>
            <options> </options>
            <processName>opera.exe</processName>
            <useSystemProxy>true</useSystemProxy>
            <capacity>1</capacity>
        </browserType>

    </browserTypes>
If needed change the <path> for your own locations of each browser!

Now you can execute test phase and enjoy the successful execution of the test.

HTTPS-Sites

As workaround for issue #131 you can follow the intructions of HTTPS support in Sahi and copy afterwards the files from java-example/target/classes/sahi/userdata/certs to java-example/src/main/resources/sahi/userdata/certs. This will copy the trusted certificates when building the project and allows a clean run.

1.2.3. Containerized Execution

1.2.3.1. Sakuli Docker Images

Docker allows you to run a Sakuli test in an isolated environment, called "container", which is always started off from the same base image. This ensures that tests always run under equal conditions.

Image OS types

The repository’s subfolder ./docker contains all source files Sakuli docker images are made of. Currently we provide images on DockerHub - Sakuli Images for:

Image tags

The build process on DockerHub is triggered by Github hooks; that means that you are always getting the current version for the two branches

  • master -> image tag "latest": contains the latest stable release of Sakuli

  • dev -> image tag "dev": contains the latest snapshot version of Sakuli

Architecture of Sakuli Containers

Each Sakuli docker image is installed with the following components:

  • Desktop environment (Xfce4)

  • VNC-Server (default VNC port 5901)

  • noVNC - HTML5 VNC client (default http port 6901)

  • Java JRE 8

  • Browsers:

    • Mozilla Firefox + Java Plugin

    • Google Chrome (Java-Plugin is no longer supported)

  • Sahi OS 5

  • Sakuli in the latest stable version

Since version 1.1.0 all containers run as non-root user. The running containers are accessible with VNC (default password: sakuli) by:

Get Sakuli Docker Images

The following example command pulls the CentOS7 image from DockerHub:

docker pull consol/sakuli-centos-xfce

Alternatively, you can build this image from the sources:

git clone https://github.com/ConSol/sakuli.git
docker build -t consol/sakuli-centos-xfce docker/sakuli-centos-xfce .
Start/test a Sakuli container

Once you have pulled/built the image, you can start a container on top of it which binds port 5901/tcp and 6901/tcp to localhost (on native docker installations; $DOCKER_IP on boot2docker):

# default tag "latest" = Sakuli stable
docker run -it -p 5901:5901 -p 6901:6901 consol/sakuli-centos-xfce
# tag "dev" = Sakuli Snapshot version of dev branch
docker run -it -p 5901:5901 -p 6901:6901 consol/sakuli-centos-xfce:dev

The container will execute a small headless self-test and exit afterwards. Read on to learn how to execute your own JavaScript or Java based tests within this containers.

Run JavaScript based Test

There are three important lines in the Dockerfile of each Sakuli image which define what has to be done on a container start:

ENV SAKULI_TEST_SUITE $SAKULI_ROOT/test
ENTRYPOINT ["/dockerstartup/startup.sh"]
  • ENTRYPOINT is the command which is executed once the container is started with docker run.

  • ENV SAKULI_TEST_SUITE is set to the path of a test suite which has to run when the container starts. By default, this is set to the built-in folder /headless/sakuli/test which contains already a small example.

There is more than one way to integrate a custom testsuite in a container, discussed in the following.

Assume you want to run a suite called suite_1 located on your host at the path /home/myuser/my-sakuli-testsuites - use one of the following ways:

docker run command

Mount the suite folder on your host into the container and override CMD from Dockerfile (=argument for ENTRYPOINT) with custom parameters for the Sakuli starter sakuli. In this way you can also give further parameters to Sakuli e.g. to use another browser (-browser chrome).

# running tests in chrome
~$ docker run -it -p 5901:5901 -p 6901:6901 consol/sakuli-centos-xfce run /headless/sakuli/test -browser chrome

To get all possible command line parameters call docker run consol/sakuli-ubuntu-xfce -help.

CMD can be overwritten in two ways:

1) Using the command line
~$ docker run -it -p 5901:5901 -p 6901:6901 -v "/home/myuser/my-sakuli-testsuites:/my-sakuli-testsuites" consol/sakuli-centos-xfce 'run /my-sakuli-testsuites/suite_1'

This command will

  • mount the test suites folder to /my-sakuli-testsuites within the container

  • execute the suite suite_1

2) Using docker-compose

See docker run command.

Environment variable SAKULI_TEST_SUITE

Mount a folder on your host into the container and overwrite the environment variable SAKULI_TEST_SUITE.

1) Using the command line
~$ docker run -it -p 5901:5901 -p 6901:6901   \\
     -v "/home/myuser/my-sakuli-testsuites:/my-sakuli-testsuites"   \\
     -e "SAKULI_TEST_SUITE=/my-sakuli-testsuites/suite_1"   \\
     consol/sakuli-ubuntu-xfce
2) Using docker-compose

See Environment variable SAKULI_TEST_SUITE.

Run Java based test

Also for Sakuli test writen in Java and executed through Maven, we provide to preconfigured docker images: consol/sakuli-xxx-xxx-java. For more information about how to write a Java based Sakuli test see Sakuli Java DSL. Now take a look at the important lines in the Dockerfile which define how the container will start:

ENV SAKULI_TEST_SUITE /opt/maven
WORKDIR $SAKULI_TEST_SUITE
ENTRYPOINT ["/root/scripts/start_hook.sh"]
  • ENV SAKULI_TEST_SUITE is set to the path of a test suite which has to run when the container starts. By default, this is set to /opt/maven which contains already a small example.

  • WORKDIR is set to the path, where the maven build will be executed. By default, this is set to the built-in example folder /opt/maven.

  • ENTRYPOINT is the script which is executed once the container is started with docker run. It starts the vnc environment and executes by default mvn clean test.

Assume you want to run the Sakuli end-2-end test from your Maven project located at the path /home/myuser/my-sakuli-maven-project you can executed the Maven build in the inside of the Sakuli container like follow:

1) Using the command line
~$ docker run -it -p 5901:5901 -p 6901:6901 -v /home/myuser/my-sakuli-maven-project:/opt/maven consol/sakuli-ubuntu-xfce-java

This command will

  • mount the test suites folder to /home/myuser/my-sakuli-maven-project within the container

  • execute the maven build with default command mvn clean test

If you want to for example also build youre maven artifacts over mvn install overwrite the default command like follow:

~$ docker run -it -p 5901:5901 -p 6901:6901 -v /home/myuser/my-sakuli-maven-project:/opt/maven consol/sakuli-ubuntu-xfce-java mvn clean install
2) Using docker-compose

See Run Java based test.

Extend a Sakuli Image with your own software

Since 1.1.0 the Sakuli image run as non-root user per default, so that mean, if you want to extend the image and install software, you have to switch in the Dockerfile back to the root user:

## Custom Dockerfile
FROM consol/sakuli-centos-xfce:v1.1.0

MAINTAINER Tobias Schneck "tobias.schneck@consol.de"
ENV REFRESHED_AT 2017-03-17
ENV TZ=Europe/Berlin

## Install a PDF viewer
USER 0
RUN yum install -y libsane-hpaio http://get.code-industry.net/public/master-pdf-editor-4.0.30_qt5.x86_64.rpm \
    && yum clean all
## switch back to default user
USER 1984
Change User of running Sakuli Container

Per default, since version 1.1.0 all container processes will executed with user id 1984. You can chnage the user id like follow:

Using root (user id 0)

Add the --user flag to your docker run command:

docker run -it --user 0 -p 6911:6901 consol/sakuli-ubuntu-xfce
Using user and group id of host system

Add the --user flag to your docker run command:

docker run -it -p 6911:6901 --user $(id -u):$(id -g) consol/sakuli-ubuntu-xfce
Override VNC environment variables

The following VNC environment variables can be overwritten at the docker run phase to customize your desktop environment inside the container:

  • VNC_COL_DEPTH, default: 24

  • VNC_RESOLUTION, default: 1280x1024

  • VNC_PW, default: sakuli

For example, the password for VNC could be set like this:

~$ docker run -it -p 5901:5901 -p 6901:6901 -e "VNC_PW=my-new-password"  \\
     consol/sakuli-ubuntu-xfce
1.2.3.2. Docker Compose
Assume you want to run a suite called suite_1 located on your host at the path /home/myuser/my-sakuli-testsuites.
Like in all docker containers you can overwrite all environment variables in a docker-compose.yml like for example the VNC_PW (Override VNC environment variables).

A more elegant way as using the docker run command to parameterize your container startup, is to pack all into a Docker Compose file. You can create docker-compose.yml to integrate a custom testsuite in a container in the following ways:

Run JavaScript based test
docker run command
To have the correct working directory, place the docker-compose.yml under /home/myuser/my-sakuli-testsuites
sakuli-example-ubuntu:
  image: consol/sakuli-centos-xfce
  ports:
  - 5901:5901
  - 6901:6901
  volumes:
  - .:/my-sakuli-testsuites
  command: run /my-sakuli-testsuites/suite_1

When executed in the same directory as docker-compose.yml, a simple docker-compose up will bring up all containers.

Intentionally, docker-compose is made to bring up environments with multiple containers which are linked together, but even with one container it eases the parameter handling.
docker-compose up --force-recreate removes all currently stopped and running containers before it starts the containers, which defined in the docker-compose.yml. Otherwise, if a normal docker-compose up will called again, the test execution will reattach the instance and the start the test execution again in the same container instance.
Environment variable SAKULI_TEST_SUITE

Similar to docker run command, the file docker-compose.yml would look like this:

sakuli-example-ubuntu:
  image: consol/sakuli-ubuntu-xfce
  ports:
  - 5901:5901
  - 6901:6901
  volumes:
  - .:/my-sakuli-testsuites
  environment:
  - SAKULI_TEST_SUITE=/my-sakuli-testsuites/suite_1
Run Java based test

Similar to the usage of Run Java based test, you can to pack all parameters into a Docker Compose file. Create docker-compose.yml:

sakuli-example-ubuntu:
  image: consol/sakuli-ubuntu-xfce-java
  ports:
  - 5901:5901
  - 6901:6901
  volumes:
  - .:/opt/maven

When executed in the same directory as docker-compose.yml, a simple docker-compose up will bring up all containers.

Intentionally, docker-compose is made to bring up environments with multiple containers which are linked together, but even with one container it eases the parameter handling.
docker-compose up --force-recreate removes all currently stopped and running containers before it starts the containers, which defined in the docker-compose.yml. Otherwise, if a normal docker-compose up will called again, the test execution will reattach the instance and the start the test execution again in the same container instance.

Like above you can for example also override the default mvn command and use a additional persistent volume for caching the maven dependencies:

version: '2'

services:
  sakuli_java_test:
    image: consol/sakuli-ubuntu-xfce-java
    volumes:
    - /home/myuser/my-sakuli-maven-project:/opt/maven
    - data:/root/.m2
    network_mode: "bridge"
    ports:
    - 5911:5901
    - 6911:6901
    command: mvn clean install
    # to keep container running and login via `docker exec -it javaexample_sakuli_java_test_1 bash`
    # command: --tail-log

volumes:
  data:
    driver: local
1.2.3.3. Kubernetes

The following section describes how to use Kubernetes for Sakuli E2E tests and monitoring. First go the folder of the Kubernetes configuration:

cd <project-path>/docker/kubernetes

You will find the kubernetes config example in: docker/kubernetes/kubernetes.sakuli.example.pod.run.yaml

Start execution pod

To execute a Sakuli E2E testing container in the kubernetes cluster create a pod:

kubectl create -f kubernetes.sakuli.example.pod.run.yaml

This creates the following components in the Kubernetes cluster:

  • a new namespace sakuli

  • a pod with the Sakuli container running

  • a service to make the container ports 6901 and 5901 accessible

Now view the running pods on the Kubernetes dashboard:

http://<kubernets-cluster-ip>:30000/#!/pod?namespace=sakuli

kubernetes container details

or get a list of all running pods in the sakuli namespace:

kubectl get pod --namespace=sakuli --show-all

You can also take a look at the log output:

kubectl logs --namespace=sakuli test-sakuli-kub

If you want to watch the test execution you can connect to the container on the external HTTP port 32001 of the service test-sakuli-kub:

http://<kubernetes-cluster-ip>:32001/vnc_auto.html?password=sakuli&view_only=true

kubernetes container via webvnc

Delete execution pod

Delete the Sakuli pod with the following command:

kubectl delete -f kubernetes.sakuli.example.pod.run.yaml
1.2.3.4. OpenShift

The following section describes how to use OpenShift for Sakuli E2E testing and monitoring.

First you have to create your OpenShift project on the command line:

cd openshift
oc new-project my-project

Then you can use the provided templates:

Run image from Dockerhub
cd openshift
oc new-project my-project

As soon as you are logged in to OpenShift and have selected your project, you can simply run the image by using the configuration openshift.sakuli.example.pod.run.yaml:

oc process -f openshift.sakuli.example.pod.run.yaml -v E2E_TEST_NAME=single-pod | oc create -f -

After the deployment you will see the new deployed service on the OpenShift management UI :

https://__YOUR-OS-MANAGEMENT-URL__/console/project/my-project/overview`

openshift management consol run-only service

Watch the test execution within the container with this URL:

http://my-run-only-pod-my-project.__YOUR-OS-URL__/?password=sakuli`

openshift container via webvnc

If you want to use another Sakuli image (here: Ubuntu) just use the IMAGE var:

oc process -f openshift.sakuli.example.pod.run.yaml -v E2E_TEST_NAME=single-pod -v IMAGE=consol/sakuli-ubuntu-icewm | oc create -f -
Build & run your own image

If you want to build the image in your own infrastructure just use the configuration openshift.sakuli.example.image.build.yaml:

oc process -f openshift.sakuli.example.image.build.yaml -v IMAGE=sakuli-oc-image | oc create -f -

Alternatively you can build a custom image in a specific branch:

oc process -f openshift.sakuli.example.image.build.yaml \
    -v IMAGE=sakuli-oc-image-icewm \
    -v SOURCE_REPOSITORY_REF=dev \
    -v SOURCE_DOCKERFILE=Dockerfile.sakuli.ubuntu.icewm \
    | oc create -f -
Use images from oc docker registry

To use an already builded image from the internal OpenShift registry you have to specify the image in the pattern <registry-ip>/<your-project>/<image-name>[:<tag>]:

oc process -f openshift.sakuli.example.pod.run.yaml -v IMAGE=10.0.0.X:5000/my-project/sakuli-oc-image,E2E_TEST_NAME=oc-image-test-2 | oc create -f -
Run git based tests
Git based test definitions on volume mounts

An effective way to execute your own Sakuli tests is that you mount the testsuite into the container. For this you can use the template openshift.sakuli.gitvolume.pod.run.yaml. The template will checkout the git repository and mount it as a read-only volume into the container where Sakuli will execute it:

oc process -f openshift.sakuli.gitvolume.pod.run.yaml \
    -v GIT_TEST_SUITE_REPO=https://github.com/ConSol/sakuli-examples \
    -v GIT_TEST_SUITE_PATH=docker-xfce/part_01/example_xfce \
    | oc create -f -
If something went wrong, you maybe have to enable this volume type in the cluster - see next section.
Enable gitRepo volumes:

Login as administrator:

oc login -u system:admin

Edit the security :

oc edit securitycontextconstraints/restricted

add gitRepo to volumes:

volumes:
- configMap
- downwardAPI
- emptyDir
- persistentVolumeClaim
- secret
- gitRepo
Other useful commands
Delete specific application or E2E test
oc process -f openshift.sakuli.example.pod.run.yaml -v E2E_TEST_NAME=single-job | oc delete --grace-period=5 -f -
Delete all running pods and configs
oc delete dc --all && oc delete routes --all && oc delete pods --all && oc delete services --all && oc delete jobs --all

1.3. Sakuli Testdefinition

1.3.1. Sakuli API

Sakuli provides methods of three different types:

  • JS/Java methods of Sahi, which can be used 100% natively

  • JS/Java methods which encapsulate a subset of the Sikuli Java API

  • JS/Java methods of Sakuli framework itself (testcase stuff, exception handling, …)

All classes and methods are implemented identical for Java and JavaScript

For the detailed documentation see:

Index

Namespaces

1.3.1.2. Sahi-API

All Sahi-API functions are natively usable in Sakuli. For a complete documentation, see Sahi-API.

Members

1.3.1.3. TestCase

TestCase - initializes the Sakuli object and sets the warning and critical time for this test case.

Params

  • warningTime number - threshold in seconds. If the threshold is set to 0, the execution time will never exceed, so the state will be always OK!

  • criticalTime number - threshold in seconds. If the threshold is set to 0, the execution time will never exceed, so the state will be always OK!

  • optImagePathArray Array.<String> - (optional) Path or Array of Paths to the folder containing the image patterns for these test cases.

Returns: - an initialized Sakuli object. Example

var testCase = new TestCase(20,30, "path-to/image-folder-name");

Members

TestCase.addImagePaths(imagePaths)

Adds the additional paths to the current image library of the TestCase. If a relative path is assigned, the current testcase folder will be used as current directory.

Params

  • imagePaths string - one or more path strings

TestCase.endOfStep(stepName, optWarningTime)

A step allows to sub-divide a case to measure logical units, such as "login", "load report" etc. in its particular runtime. When a case starts, Sakuli starts a "step" timer. It gets read out, stored with the step name, and resetted each time endOfStep() is called. If the step runtime exceeds the step threshold (second parameter, optional), the step is saved with state "WARNING" (there is no CRITICAL state).

Params

  • stepName String

  • optWarningTime number - (optional) threshold in seconds, default = 0. If the threshold is set to 0, the execution time will never exceed, so the state will be always OK!

TestCase.handleException(e)

Handles any Exception or Error. The handleException function calls the Java backend and stores the Exception for further processing.

Use it at the end of a catch-block.

Params

  • e Error - any Exception or Error

Example

try {
  ... do something
} catch (e) {
    sakuli.handleException(e);

1.3.2. Additional Topics

This page contains different topics regarding the configuration of both Sakuli and its components: Sahi and Sikuli.

1.3.2.1. Property loading mechanism

Sakuli properties are predefined in SAKULI_HOME/config/sakuli-default.properties; these values should/can be overridden in the following order (last match wins):

  1. as a global testsuite property in test-suites-folder/sakuli.properties -> valid for all test suites within this folder

  2. as a testsuite property in test-suites-folder/test-suite/testsuite.properties -> valid for the test suite itself and all test cases within it

  3. as a Java VM option like -D log.level.sakuli=DEBUG, as option of the Sakuli starter -> valid for only one test run

We do not recommend to change any values in SAKULI_HOME/config/sakuli-default.properties as a new version of Sakuli will have its own default property file and would overwrite the existing one; your changes would not be preserved.

1.3.2.2. Exception handling

Some objects (Region, Application, Environment) allow on their creation to specify the optional boolean argument resumeOnException, which controls whether the script should resume on an exception which is related to the object or one of its method (default: false).

Setting this to true can be useful if you want to raise a custom exception or no exception at all.

Table 3. Property values of sakuli.exception.suppressResumedExceptions
Value Impact

true

the exception will be logged and appear in the test result

false

the exception will NEITHER be logged NOR appear in the test result.

Example:
// create region "foo"
var foo = new Region("bar.png",true);
// if "image" is not found, the script will resume
var baz = foo.find("image");
// throw your "own" exception.
// If you do not, and suppressResumedExceptions=true, the exception will be suppressed.
if (baz == null){
    throw "Sorry, I could not find image 'image'.";
}
1.3.2.3. Logging
Verbosity

The logging verbosity of all compoments Sakuli, Sahi, Sikuli, Spring - and Java in general can be changed individually with properties.

"Verbosity" means one of the levels DEBUG - INFO - WARN - ERROR
Table 4. Log level verbosity properties
Property Description

log.level.sakuli=LEVEL

logging level for Sakuli output

log.level.sikuli=LEVEL

logging level for Sikuli output

log.level.sahi=LEVEL

logging level for Sahi output

log.level.spring=LEVEL

logging level for the Spring framework (only used internally)

log.level.root=LEVEL

logging level for all other Java classes and libraries

Table 5. Log file folder / pattern
Property Description

sakuli.log.pattern=%-5level [%d{YYYY-MM-dd HH:mm:ss.SSS}] - %msg%n

Format string

sakuli.log.folder=${sakuli.testsuite.folder}/_logs

Log folder

In general it is also possible to add your own Logback configuration under SAKULI_HOME/config/sakuli-log-config.xml. For more information about the Logback syntax please refer to the Logback manual.

Log file rotation

Control the age of your log-files in the sakuli.properties, to prevent disk space erros.

Property Description

sakuli.log.maxAge=14

Deletes all files that are older than (default) 14 days in the defined sakuli.log.folder.

On Linux you can additional configure logrotate to tidy up old log files:

vim /etc/logrotate.d/sakuli

__SUITE_FOLDER__/*/_logs/* __SUITE_FOLDER__/*/_logs/_screenshots/* {
    size 1k
    missingok
    maxage 2
}
1.3.2.4. Secret De-/Encryption
Interface selection

Neither Sahi nor Sikuli have a way to prevent sensible data (passwords, PINs, etc.) from being logged and stored in the script in clear text.

That’s the reason why Sakuli is able to encrypt them on the command line, and to decrypt them again on runtime just for the moment when they are needed. There is no (quick) way to decrypt those secrets again on the command line, so this is rather a way to obscure things not everybody should see than high-secure a encryption mechanism.

Among other parameters, Sakuli uses the MAC address of a local network interface card as a encryption salt. Hence no virtual adapters can be choosen.

You can decide whether Sakuli should automatically select an adapter by setting the following properties:

sakuli.encryption.interface.autodetect=true

..or a specific one should be used:

sakuli.encryption.interface.autodetect=false
sakuli.encryption.interface=eth0
Encrypt a secret

To encrypt secrets on the command line, Sakuli uses the MAC address of a NIC on the local machine (Windows/Linux). The following command lets Sakuli decide which NIC will be used:

sakuli encrypt foo
=========== Calling Sakuli JAR: java -classpath C:\Program Files (x86)\sakuli\sakuli-v0.9.3-SNAPSHOT\libs\jav\sakuli.jar;C:\Program Files (x86)\sakuli\sakuli-v0.9.3-SNAPSHOT\libs\java\* org.sakuli.starter.SakuliStarter --sakuli_home C:\Program Files (x86)\sakuli\sakuli-v0.9.3-SNAPSHOT --encrypt foo ===========

String to Encrypt: foo
...
Encrypted secret with interface 'eth3': CKXIAZmO7rSoBVMGgJZPDQ==

... now copy the secret to your testcase!

Add -interface eth0 to select eth0 as salt interface. Add -interface list to get a list of all available adapters.

Decrypt a secret

To decrypt and use a secret in Sakuli test cases, use one of the following methods:

1.3.2.5. Screenshot settings

To set the format and destination folder for screenshots taken by Sakuli change the following properties:

Property Description

sakuli.screenshot.onError=true

take a screenshot in case of an exception

sakuli.screenshot.dir=${sakuli.log.folder}/_screenshots

folder for screenshot files (if activated)

sakuli.screenshot.format=jpg

screenshot file format (Possible values: jpg, png)

sakuli.forwarder.gearman.nagios.template.screenshotDivWidth=640px

Screenshot dimensions for results sent to Gearmand

1.3.2.6. GUI-only tests

If you want to run tests which do not include any web technology, you can use phantomJS instead of firefox/chrome/IE and use the Sahi default start URL:

testsuite.suite
case1/sakuli_demo.js http://sahi.example.com/_s_/dyn/Driver_initialized
Sakuli depends on Sahi running, which in turn needs a running browser instance. Using PhantomJS for this, hides the browser window completely.
1.3.2.7. Sahi Controller
Use the Sahi Controller to identify elements on the page to write and test Sahi methods!

There are two ways to get Sahi instructions into your testcase your-testcase.js:

  • identify, copy & paste from the Sahi Controller

  • record by the Sahi Controller, copy & paste from the file, see Sahi Recorder

Open the Sahi Controller

Add to your testcase the following line, at position where you want to identify your HTML object:

//.... your testcode
env.sleep(9999);

Then start your test suite and the Sakuli test should appear and stop at that position for 9999 seconds. The "sleep" statement is a nice trick when writing long tests; wherever you put a 9999s sleep in, the test will execute until this position and wait. Think of it like a breakpoint when debugging a program.

Now open the Sahi Controller (hold the ALT key on Windows or CTRL + ALT on Linux and doubleclick anywhere on the page) to open this window:

sahi_controller

copy/paste code

First, we want Sahi to check if there is for example the Sakuli Logo on the page. Hold the CTRL key and move the mouse pointer on the logo. Watch the Sahi Controller: it detects the HTML elements below the mouse pointer and generates the accessor method for "image" automatically:

logo_accessor

Click on "Assert" to let Sahi autogenerate assertion methods:

assert

Just copy the second line (which checks the visibility of an element) into the clipboard and paste it into your testcase your-testcase.js before the env.sleep(9999) statement.

Further, we want for example to assure that the contact form of the web page os displayed correctly. Move the mouse pointer down to the "Kontakt" link; Sahi should display the accessor _image("Kontakt zu ConSol")

  1. This time use the "click" button on the controller

  2. To execute a click; this also generates the complete browser action statement

  3. copy/paste also into the test case

click

In the end, Sahi should check that the appeared popup window contains the text "Schreiben Sie uns!". You guessed it - move the mouse pointer over this text and click the "Assert" button again. The fourth assertion is the right one, which we also paste into the test script:

contains_text

Now remove the "sleep" statement from the script file; it should look now like that:

_dynamicInclude($includeFolder);
var testCase = new TestCase(60, 70);
var env = new Environment()

try{
    //your code
    _assert(_isVisible(_image("sakuli.png")));
    _click(_image("Kontakt zu conSol"));
    _assertContainsText("Schreiben Sie uns!", _heading3("Schreiben Sie uns!"));
    //env.sleep(9999);

} catch (e) {
    testCase.handleException(e);
} finally {
    testCase.saveResult();
}
Perhaps you want Sahi to highlight the items it is acting on: just use the _highlight() method from the debug helper API to mark each element with a red border before accessing it: _highlight(_image("sakuli.png"));
1.3.2.8. Sahi Recorder

Another method to copy/paste code is to record all steps into a file. For this, open the Sahi controller (Open the Sahi Controller), enter a filename and click on "record":

sahi_recorder

actions like clicks are written to file automatically. All other actions like assertions can be written to file by clicking the button "Append to Script": sahi_recorder_append_to_script

After you have clicked on "stop", open the recorded file, copy everything and paste the lines in to the Sakuli testcase your-testcase.js file.

1.3.2.9. Sahi settings
Browser selection

You may want to change the browser due to the following reasons:

  • to check if a web test (made with Sahi methods) for browser A is also running properly on browser B

  • to run a headless browser

    • just for curiosity :-)

    • to keep the browser in background while Sakuli tests a non-web application (e.g. fat client)

In addition to the possibilities described property testsuite.browser, see Property loading mechanism, the generic Sakuli starter sakuli/sakuli.exe can also be given the parameter -browser:

sakuli run /path/to/suite -browser chrome
Browser configuration

If the Sahi dashboard does not show any browser or if you want to add another browser to the dashboard …

nobrowser

… you have to edit SAHI_DIR/userdata/config/browser_types.xml. Each browser is defined within a browserType block. Please refer to the Sahi Documentation, "Configure Browsers" to see the browserType Nodes for popular browsers.

For PhantomJS please save sahi.js into the folder SAHI_DIR\phantomjs\ and use this option line:

        <options>--proxy=localhost:9999 __SAHI_DIR__\phantomjs\sahi.js</options>

Attention: PhantomJS 2 is currently unsupported. Use version 1.9.x

Sahi behind a proxy

Set the following properties (globally in sakuli.properties) to define a proxy Sahi should connect to.

### HTTP/HTTPS proxy Settings

HTTPS support in Sahi

This documentation is not complete yet. Any help is appreciated.

Solution 1: accept self-signed certificates

This will work on most systems, especially the ones you have full control over.

  1. Open Sahi Dashboard, start the browser.

  2. On the Sahi start page, navigate to the https site you want Sahi to trust (e.g. https://github.com)

  3. You will be presented a message that this page "connection is not secure/trusted".

  4. On Firefox, click "I understand the risks."

  5. On Chrome, click "Proceed anyway (unsecure)"

  6. On IE, click "Continue to the website (not recommended)".

  7. Once the page has loaded, click "SSL Manager" from the Sahi start page

  8. You should be presented a green check mark right of the https URL, indicating that Chrome accepted the site’s certificate, signed by Sahi:

https_ok

Solution 2: manual certificate import
This is a browser-specific solution and can be different in newer Browser versions or other operating systems!
Google Chrome (Windows)
  1. Open Sahi Dashboard, start Chrome

  2. On the Sahi start page, navigate to the https site you want Sahi to trust (e.g. https://github.com )

  3. You will be presented a message that this page "connection is not secure". Click on the red-crossed locker symbol left of the URL in the address bar and then "Certificate information"

  4. Change to tab "Details" and press "Copy to File…"

  5. In the following export assistent, save the certificate as "Cryptographic Message Syntax Standard PKCS #7 Certificates (.P7B)""

  6. Go to Chrome preferences, "Manage certificates"

  7. "Import…" -> select the exported .p7b certificate (in the "Open" dialogue, chnange the filename extension filter to "PKCS#1" )

  8. Choose "Trusted Root Certification Authorities" as certificate store

  9. Accept the Import confirmation.

  10. Restart Chrome from the Sahi dashboard.

  11. From the Sahi start page (step #2), click "SSL Manager"

  12. You should be presented a green check mark right of the https URL, indicating that Chrome accepted the site’s certificate, signed by Sahi:

https_ok

Mozilla Firefox
  1. Open Sahi Dashboard, start Firefox/Firefox portable

  2. On the Sahi start page, navigate to the https site you want Sahi to trust (e.g. https://github.com )

  3. You will be presented a message that this page "connection is not secure". Click on I understand the risks" and add the certificate exception. Now navigate back to the sahi start page and click on the Link "SSL Manager":

ssl manager

You will be promptet again a security warning for connecting to "sahi.example.com" (a local dummy domain), add the certificate here also as an exception.

The following page contains a list of all so far trusted and untrusted domains and their certificates. To import the red marked into the browser’s certificate store, open the links by clicking them with the middle mouse key. This opens the page within a new tab; only in this way you are allowed to add the certificate exception.

certs

You can close every opened tab when it is displaying "Successfully connected" for the domain:

connected

Now go back to the SSL Manager overview and click the "refresh" button. Every previously untrusted domain should now be marked as OK:

refresh

Internet Explorer

See Sahi description Configure SSL in Sahi.

1.3.2.10. Sikuli settings
Highlighting Regions
Property Description

sakuli.highlight.seconds=1.1f

duration for auto-highlighting and highlight() method

sakuli.autoHighlight.enabled=false

If true, every region gets highlighted automatically for sakuli.highlight.seconds

1.3.3. Troubleshooting

1.3.3.1. Growing Firefox profile folder

If you experience that the Sahi profile folders sahi0-9 of Mozilla Firefox (located in sahi\userdata\browser\ff\profiles) are getting bigger and bigger: this is caused by two bugs:

We do not know any Firefox settings which can prevent the creation of SQLITE writeahead-logs (if you do, please let us know). The only pragmatic solution at the moment is to delete all SQLITE files periodically or before each Sakuli run (e.g. by running as a preHook). %SAKULI_HOME%\bin\helper\ff_purge_profile.bat contains an example for windows.

1.3.3.2. Hanging applications

If you are testing applications which tend to hang/freeze, you can run a "tidy-up"-Script by using the -pre-Hook option of Sakuli:

sakuli run __INST_DIR__/example_test_suites/example_ubuntu/ -preHook 'cscript.exe %SAKULI_HOME%\bin\helper\killproc.vbs -f %SAKULI_HOME%\bin\helper\procs_to_kill.txt'

In procs_to_kill.txt you can define which processes should be killed before Sakuli starts a new check:

# Full path:
C:\Program Files\Mozilla Firefox\firefox.exe
C:\Program Files\Internet Explorer\iexplore.exe
# Using wildcards (%):
java%sakuli.jar
1.3.3.3. Sikuli does not recognize images

If Sikuli does not recognize regions on the screen or does recognize the wrong ones, check the following list of possible reasons:

  • Run the client’s OS on a fixed resolution: Some applications/OS scale window elements slightly depending on the resolution. for example, if you are running Sakuli within Virtualbox, the guest OS changes its resolution as soon as you resize the VM window. The dimensions of window elements can then slightly diverge by 1-2 pixels from the screenshots taken before. This difference is small for human’s eyes, but a big one for Sikuli. Make sure to disable features like "Auto-Adjust Guest Display" and set the Client’s desktop to a common resolution (e.g. 1024x768). Side note: the smaller you set the resolution, the less work has to be done by Sikuli.

  • Disable any image compression algorithms in your screenshot capturing program (Greenshot, Shutter, …). Otherwise Sikuli will compare compressed pattern images with umcompressed image data on the screen, which will fail for sure.

  • Sikuli uses a similarity value of 0.99 by default. That value (range: 0-0.99) determines that more than (X * 100) % of the region pixels have to match. If Sikuli does not recognize anything or the wrong regions, try to slightly decrease the similarity** by changing 'sakuli.region.similarity.default' globally or inside a test e.g. with env.setSimilarity(0.8). This should only be neccessary if the pattern images are of poor quality or the screen always differs slightly from the pattern images (e.g. due to compression of remote sessions like vnc). Please note that a similarity of "1" would mean that "more than 100%" of the region pixels would have to match - which is completely wrong.

1.3.3.4. Missing keystrokes on type or failing paste

Sikuli keyboard events (type()`and `paste()) on a Sahi-controlled browser instance can get lost if they are executed at the same time when Sahi internal status requests are sent from the browser to the Sahi proxy (default: 10x per sec).

For this reason, Sikuli type/paste methods first extend the Sahi status interval to the value of sahi.proxy.onSikuliInput.delayPerKey (in ms) which is long enough to execute one keyboard action. For the method type (which is "press/release character by character""), a multiple if this value is chosen. Before leaving the paste/type method, the interval gets reset by Sakuli to the default Sahi status interval.

This setting is not needed if Sikuli does keyboard actions on GUIs not controlled by Sahi.

1.3.3.5. Application.getRegion() returns NULL

If the execution of new Application("…​").open().getRegion() throws a NullPointerException or retruns null, firstly turn on debug logging, see [logging]. Then you mostly will see at the log output that an OS based library is missing.

On Ubuntu or other Linux based OS check if the packe wmctrl is installed. If not install it via:

sudo apt-get install wmctrl

1.4. Integration in other Tools

Sakuli can hand over test result to "Forwarder", which can be currently feed different tools like Nagios based monitoring systems or continuous integration server. If no forwarder is defined, a result summary is printed out in the end of a suite.

Feel free to develop another forwarder or ask us to do this.

1.4.1. Monitoring integration

1.4.1.1. OMD preparation

This chapter describes all necessary steps to prepare a OMD site with a Nagios compatible monitoring system to receive Sakuli test results with one of the forwarders gearman, database, Check_MK or icinga2-api. For some parts of this documentation, OMD with Thruk as web frontend will be presupposed, but any other Nagios based system will do also (the configuration steps may vary then).

If you want to run OMD-Labs in a container then check out the OMD-Labs on Docker project.
Requirements
  • OMD installed on a Linux operating system

  • a running OMD site

HTML escaping

Sakuli will produce HTML formatted output. HTML escaping in the monitoring core must be turned off:

OMD[sakuli]:~$ vim etc/nagios/cgi.cfg
    escape_html_tags=0

Now choose one of the Sakuli forwarder modules.

1.4.1.2. Gearman forwarder

This page describes how the results of Sakuli tests can be transmitted directly into the Gearman result queue of a monitoring system.

If you do not use a gearman-enabled monitoring system in a OMD environment, the procedure may vary.

sakuli-db-forwarder

OMD Configuration
Enable the site’s mod-gearman server

Stop the OMD site:

OMD[sakuli]:~$ omd stop

Start the OMD configuration menu

OMD[sakuli]:~$ omd config

Select Distributed Monitoring and

  • -> GEARMAND -> ON

  • -> GEARMAND_PORT -> OMD_IP:GEARMAN_PORT (default: 4730)

  • -> GEARMAN_NEB -> ON

  • -> GEARMAN_WORKER -> OFF # only if workers aren’t still used

  • -> MOD_GEARMAN -> ON

As Sakuli only uses the result queue of gearmand, you can disable all other queues unless you are using mod-gearman for regular checks:
OMD[sakuli]:~$ vim ~/etc/mod-gearman/server.cfg
eventhandler=no
services=no
hosts=no
do_hostchecks=no

Restart OMD:

OMD[sakuli]:~$ omd start
Create a Nagios service

Use the Makefile located in $OMD_ROOT/share/sakuli/ to install predefined Nagios/Naemon service templates (optional):

OMD[foo]:~/share/sakuli/setup$ make config
cp ./omd/etc/nagios/conf.d/sakuli_nagios_templates.cfg /omd/sites/foo/etc/core/conf.d/
omd reload core
Reloading naemon configuration (PID: 17405)... OK

Create a service which should receive Sakuli test results. Host/service names derive from the following properties:

  • host: sakuli.forwarder.gearman.nagios.hostname (defined globally or per suite)

  • service: testsuite.id (defined in testsuite.properties)

define service {
  service_description            example_xfce
  host_name                      sakuli_client
  use                            tpl_s_sakuli_gearman
  freshness_threshold            180
}
freshness_threshold should be slightly higher than the interval Sakuli tests are executed

The check is waiting now for check results from a Sakuli client.

Sakuli Client Configuration
Modify Sakuli gearman forwarder parameter

On the Sakuli client you must set the global properties for the gearman receiver. For this, edit sakuli.properties in the folder containing the test suites (you can copy the lines from SAKULI_HOME/conf/sakuli-default.properties):.

__INST_DIR__/example_test_suites/sakuli.properties:

sakuli.forwarder.gearman.enabled=true
sakuli.forwarder.gearman.encryption=false
sakuli.forwarder.gearman.secret.key=secret_password
sakuli.forwarder.gearman.server.host=__GEARMAN_IP__
sakuli.forwarder.gearman.server.port=[Gearman Port defined in "omd config" (default:4730)]
sakuli.forwarder.gearman.server.queue=check_results (1)

# Nagios host where all Sakuli services are defined on. If neccessary, override this value per test suite.
# (Nagios service name is defined by testsuite.properties -> suiteID)
sakuli.forwarder.gearman.nagios.hostname=sakuli_client
sakuli.forwarder.gearman.nagios.check_command=check_sakuli
1 Change this queue name if you use the Sakuli Gearman proxy
Using AES encryption (optional)

The gearman forwarder supports AES encryption when sending checked results to the OMD server. The AES encryption uses a 32 byte (256 bit) secret key that has to be given in the properties.

sakuli.forwarder.gearman.encryption=true
sakuli.forwarder.gearman.secret.key=secret_password

In case you get a java.lang.security.InvalidKeyException with error message "Illegal key size or default parameters" you probably need to enable unlimited strength security policies in your Java JRE. This is done by adding a special security policy JAR to the Java JRE lib directory. For the Java JRE 8, take a look at Oracle - Java Cryptography Extension 8.

On the server side (OMD) you have to enable the encryption feature of mod-gearman. Therefore the following two steps are necessary:

1) Set the server side encryption password:

 OMD[sakuli]:~$ echo "secret_password" > ~/etc/mod-gearman/secret.key

2) Enable the encryption and disable accept_clear_results in the config file:

 OMD[sakuli]:~$ vim ~/etc/mod-gearman/server.cfg

encryption=yes
accept_clear_results=yes
Gearman proxy (optional)

gearman_proxy

Use the Sakuli gearman proxy script if you want to intervene into the communication between Sakuli and Naemon/Nagios.

Possible use cases:

  • Change parts of the messages Sakuki sends to the monitoring system ⇒ there are some examples contained already

  • Getting notified when Sakuli sends results to services which do not exists

  • Auto-create services for incoming results (not yet implemented)

Use the Makefile located in $OMD_ROOT/share/sakuli/ to enable the feature:

OMD[demo]:~/share/sakuli/setup$ make gearman_proxy
cp ./omd/etc/init.d/sakuli_gearman_proxy /omd/sites/demo/etc/init.d/
chmod +x /omd/sites/demo/etc/init.d/sakuli_gearman_proxy
cp ./omd/local/bin/sakuli_gearman_proxy.pl /omd/sites/demo/local/bin/
cp ./omd/etc/mod-gearman/sakuli_gearman_proxy.cfg /omd/sites/demo/etc/mod-gearman/

Edit etc/mod-gearman/sakuli_gearman_proxy.cfg:

$remoteHost="172.17.0.2"; (1)
$remotePort="4730"; (1)
$localHost="172.17.0.2"; (2)
$localPort="4730"; (2)
$queues = {
    "$remoteHost:$remotePort/check_results_sakuli"  => "$localHost:$localPort/check_results",
}; (3) (4)

$err_h = 'error_host'; (5)
$err_s = 'eror_svc';
$err_r = '2'; (6)
1 Gearman IP/Port listening for Sakuli results. Set this to the same values as <2> unless gearman_proxy.pl is running on another system.
2 Gearman IP/Port of the monitoring system
3 check_results_sakuli ⇒ queue name to receive Sakuli results. Make sure this queue name is defined in property sakuli.forwarder.gearman.server.queue on all Sakuli clients (see Sakuli Client Configuration)
4 check_results ⇒ default queue of mod-gearman where gearman workers write back their results. (no need to change that)
5 The proxy does a livestatus query for each incoming package to ensure that the receiving host/service exists. Provide a special "error host/service" pair where the proxy can send a message when there are results coming in for non-existent services.
6 Status of messages for non-existent services (2=CRITICAL)

Start the proxy:

OMD[demo]:~$ omd start sakuli_gearman_proxy
Starting sakuli_gearman_proxy...OK

Check that the queue check_results_sakuli is running in addition to the default queue check_results.

OMD[demo]:~$ gearman_top
2017-06-09 13:37:28  -  localhost:4730  -  v0.33

 Queue Name           | Worker Available | Jobs Waiting | Jobs Running
-----------------------------------------------------------------------
 check_results        |               1  |           0  |           0
 check_results_sakuli |               1  |           0  |           0
-----------------------------------------------------------------------
This change does affect other monitoring checks executed with mod-gearman, because only Sakuli will send results into the queue check_results_sakuli.
1.4.1.3. Database forwarder

This page describes how the results of the Sakuli tests (e.g. example_windows7/ubuntu/opensuse) can be written into a MySQL database which is then checked asynchronously by the monitoring system with check_mysql_health.

If you do not use MySQL in a OMD environment, the procedure may vary.

sakuli-db-forwarder

OMD Configuration
Enabling the site’s MySQL Database

If not already done for other reasons, a site-specific MySQL instance has to be started. That’s the place where all Sakuli clients will store their check results.

Stop the OMD site and start the OMD configuration menu:

OMD[sakuli]:~$ omd stop
 ...
OMD[sakuli]:~$ omd config

Select Addons -> MYSQL -> ON and exit the menu.

Open ~/.my.cnf and set the following values:

OMD[sakuli]:~$ vim .my.cnf
# make sure to choose a free port, e.g. 3007
port = __DB_PORT__
# bind on all interfaces
bind-address = 0.0.0.0
# enable network access
#skip-networking

Create the system tables for the new database and start OMD afterwards. You should see now OMD coming up with a dedicated MySQL instance:

OMD[sakuli]:~$ mysql_install_db
OMD[sakuli]:~$ omd start
Starting dedicated Apache for site sakuli...OK
Starting MySQL... .OK.
Starting rrdcached...OK
Starting npcd...OK
Starting nagios...OK
Initializing Crontab...
create Sakuli DB and user
  1. Create the Sakuli database as described here: Create Sakuli DB

  2. Check the connection with check_mysql_health:

OMD[sakuli]:~$  lib/nagios/plugins/check_mysql_health -H __DB_IP__ --username __DB_USER__ --password __DB_PASSWORD__ --database sakuli --port __DB_PORT__ --mode connection-time
  OK - 0.24 seconds to connect as sakuli | connection_time=0.2366s;1;5
create Nagios check

Nagios fetches Sakuli check results using the plugin check_mysql_health, which is already contained in OMD.

CheckMySQLHealthSakuli.pm

The Perl module CheckMySQLHealthSakuli.pm enhances the functionality of check_mysql_health by introducing the mode --my-sakuli-suite.

Create a config directory for check_mysql_health and copy the module there:

OMD[sakuli]:~$ mkdir etc/check_mysql_health
OMD[sakuli]:~$ cp __TEMP__/setup/nagios/CheckMySQLHealthSakuli.pm etc/check_mysql_health/
resource.cfg

Set USER macros for static vars in resource.cfg, which makes it easy to use them in all nagios checks:

OMD[sakuli]:~$ vim ~/etc/nagios/resource.cfg
  # database name
  $USER10$=sakuli
  # database user
  $USER11$=__DB_USER__
  # database password
  $USER12$=__DB_PASSWORD__
  # database port
  $USER13$=__DB_PORT__
  # check_mysql_health module dir
  $USER15$=/opt/omd/sites/sakuli/etc/check_mysql_health/
  # database IP
  $USER16$=__MySQL_Database_IP__
Nagios configuration

Create a new check_command:

OMD[sakuli]:~$ vim etc/nagios/conf.d/commands.cfg

# check_command for Sakuli
# --name = Suite ID
# --name2 = number of seconds the last result is allowed to be old
define command {
  command_name                   check_sakuli
  command_line                   $USER1$/check_mysql_health \
    --hostname=$USER16$ \
    --database=$USER10$ \
    --username=$USER11$ \
    --password=$USER12$ \
    --mode=my-sakuli-suite \
    --name='$ARG1$' \
    --name2=$ARG2$ \
    --report=html \
    --port=$USER13$ \
    --with-mymodules-dyn-dir=$USER15$
}

Create a host object for Sakuli database checks (the checks are executed on the local machine, but belong logically to sakuli_client):

OMD[sakuli]:~$ vim etc/nagios/conf.d/hosts.cfg

define host {
  host_name                      sakuli_client
  alias                          sakuli_client
  address                        __SAKULI_CLIENT_IP__
  use                            generic-host
}

Create the following service object for the first test case. Note the ARG2 in check_command: the database check will only evaluate the last result if it is max. 180 seconds old. If older, the check will return UNKNOWN. (For comparison: this is equivalent to "freshness_threshold" if you would use the Gearman forwarder. In any case, you should set the RRD heartbeat to the same value to get a gap in the graph if recent client results are missing. )

OMD[sakuli]:~$ vim etc/nagios/conf.d/services.cfg

define service {
  # service_description            example_windows7
  # service_description            example_opensuse
  service_description            example_ubuntu
  host_name                      sakuli_client
  use                            generic-service,srv-pnp
  check_command                  check_sakuli!sakuli_demo!180
}

Reload OMD:

omd reload

Now open Thruk; you should see now the Sakuli host with one service attached:

omd_pending

Re-scheduling this service should display the UNKNOWN message that the requested suite could not be found. For the moment, this is ok:

omd_unknown

Sakuli Client Configuration
Modify Sakuli database forwarder parameter

On the Sakuli client you must set the global properties for the database receiver, as described here: Enable database forwarder

Test result transmission to OMD

Execute one of the example test case:

  • Ubuntu: sakuli run INST_DIR/example_test_suites/example_ubuntu/

  • openSUSE: sakuli run INST_DIR/example_test_suites/example_opensuse/

  • Windows 7: sakuli run INST_DIR\example_test_suites\example_windows7\

  • Windows 8: sakuli run INST_DIR\example_test_suites\example_windows8\

The service should change its status to:

omd_pending2

omd_pending2

Database cleanup (optional)

Sakuli’s database can get very large over time. Use the following database maintenance script to keep only the most recent data.

OMD[sakuli]:~$ cp `__SAKULI_HOME__/bin/helper/mysql_purge.sh local/bin/`

Create a OMD crontab entry for a automatic database cleanup of data older than 90 days:

OMD[sakuli]:~$ vim etc/cron.d/sakuli
00 12 * * * $OMD_ROOT/local/bin/mysql_purge.sh 90 > /dev/null 2>&1

After that, reload the OMD crontab:

OMD[sakuli]:~$ omd reload crontab

Troubleshooting
Apparmor prevention on MySQL

Possible error 1: mysql_install_db fails:

141021 16:40:03 [Warning] Can't create test file /omd/sites/sakuli/var/mysql/omd2.lower-test
ERROR: 1005  Can't create table 'db' (errno: 13)

Possible error 2: MySQL startup fails:

OMD[sakuli]:~$ omd start
Starting gearmand...OK
Starting MySQL... ..........ERROR.
Starting rrdcached...OK

Solution:

Check /var/log/syslog or /var/log/messages for apparmor messages:

…
Oct 21 17:08:21 omd2 kernel: [116300.215520] type=1400 audit(1413904101.323:27): apparmor="DENIED" operation="open" profile="/usr/sbin/mysqld" name="/opt/omd/sites/sakuli/.my.cnf" pid=13136 comm="mysqld" requested_mask="r" denied_mask="r" fsuid=999 ouid=999
…

Apparmor has prevented you from using a non-default config file for MySQL. If you know how to create a apparmor profile for MySQL on OMD, let us know :-)

The quick solution is to completely disable apparmor. Check if unloading apparmor profiles solves the problem:

root@omd:~# service apparmor teardown
 * Unloading AppArmor profiles

If so, execute the following command to uninstall apparmor:

root@omd2:~# apt-get remove apparmor
1.4.1.4. Icinga2 forwarder

This page describes how the results of Sakuli tests can be sent to the REST API of an Icinga2 monitoring instance.

This part of the documentation does not apply to OMD. Some steps may vary for Icinga2 on OMD.

sakuli-icinga2

Icinga2 Configuration
Enable the Icinga2 API

The steps to enable the Icinga2 API are described in the REST API documentation.

Create a Icinga2 service

Create a check_command, which will be executed only if Icinga did not receive a Sakuli result within a certain time. This ensures that you get a notification even if no passive check results arrive in Icinga at all:

vim /etc/icinga2/conf.d/commands.conf

object CheckCommand "check_dummy" {
   import "plugin-check-command"
   command = [
     PluginDir + "/check_dummy","$dummy_state$","$dummy_text$"
   ]
   vars.dummy_state = 0
   vars.dummy_text = "Check was successful."
}

object CheckCommand "check_sakuli" {
   import "check_dummy"
   vars.dummy_state = 3
   vars.dummy_text = "No passive Sakuli check result received."
}

Create a host object for the Sakuli client:

vim /etc/icinga2/conf.d/hosts.conf

object Host "sakuliclient01" {
   import "generic-host"
   address = [IP]
}

Create the following service object for the first test case. freshness_threshold should be slightly higher than the interval Sakuli tests are planned (if you are using PNP4Nagios, see also RRD heartbeat )

object Service "sakuli_demo" {
  import "generic-service"
  host_name = "sakuliclient01"
  check_command = "check_sakuli"
  enable_active_checks = 0
  enable_passive_checks = 1
  enable_flapping = 0
  volatile = 1
  enable_perfdata = 1
}

Reload Icinga2:

service icinga2 reload

Now open Icingaweb2; you should see the Sakuli host with the service "sakuli_demo" attached:

icingaweb2-pending2

The check is waiting now for check results from a Sakuli client.

Sakuli Client Configuration
Sakuli Icinga2 forwarder parameter

On the Sakuli client you must set the global properties for the Icinga2 receiver. For this, edit sakuli.properties in the folder containing the test suites (you can copy the lines from SAKULI_HOME/conf/sakuli-default.properties):

## En-/disable Icinga2 forwarder, default: false
sakuli.forwarder.icinga2.enabled=true
sakuli.forwarder.icinga2.api.host=__ICINGA_IP__
sakuli.forwarder.icinga2.api.port=5665
sakuli.forwarder.icinga2.api.username=icingasakuli
sakuli.forwarder.icinga2.api.password=icingasakuli
sakuli.forwarder.icinga2.hostname=sakuliclient01

For other OPTIONAL gearman parameters you can adjust, see sakuli-default.properties file.

Test result transmission to Icinga2

Execute one of the example test case:

  • Ubuntu: sakuli run INST_DIR/example_test_suites/example_ubuntu/

  • openSUSE: sakuli run INST_DIR/example_test_suites/example_opensuse/

  • Windows 7: sakuli run INST_DIR\example_test_suites\example_windows7\

  • Windows 8: sakuli run INST_DIR\example_test_suites\example_windows8\

The service in Icnga2 should change its status to:

icinga_ok

Graph settings

Icinga2 integration is very new; we did not yet dive into the configuration of Graphite or Grafana graphs. The only supported graphing solution is PNP4Nagios. Nevertheless you are welcome to contribute graph templates for Grafana and/or Graphite!

PNP4Nagios

Set the RRD storage type of PNP to MULTIPLE, which creates one RRD file per perfdata label:

echo "RRD_STORAGE_TYPE = MULTIPLE" > /etc/pnp4nagios/check_commands/check_sakuli.cfg

Copy the PNP graph template check_sakuli.php from %SAKULI_HOME%/setup/nagios/ on the client to /usr/share/nagios/html/pnp4nagios/templates/ on the Icinga2 server.

Grafana

tbd

Graphite

1.4.1.5. Check_MK

This page describes how to setup a Sakuli client to send results to a Check_MK monitoring system.

sakuli-checkmk

Sakuli Client Configuration

It is assumed that the client is already monitored by Check_MK and a agent is installed and running on it.

Spool folder

Create a new folder spool in the installation path of the Check_MK agent. This is the folder where the results will be written to. The user which is used to run Sakuli checks must be given write access to this folder.

Forwarder configuration

Now set the properties for the check_mk receiver. For this, edit sakuli.properties in the folder containing the test suites (you can copy the lines from SAKULI_HOME/conf/sakuli-default.properties):

INST_DIR/example_test_suites/sakuli.properties:

  • sakuli.forwarder.check_mk.enabled=true

  • sakuli.forwarder.check_mk.spooldir=C:\\Program Files (x86)\\check_mk\\spool - Path to the spool folder as defined above. On Windows, the backslashes have to be escaped with \. Check_MK is expecting the result files from Sakuli here. Default value: /var/lib/check_mk_agent/spool (Linux) / (installation_path)\\spool (Windows).

  • sakuli.forwarder.check_mk.freshness - Defines the maximal age in seconds in which the result is still valid. If the last modification of the result file is older than this property, the result file will be ignored. The check_mk service will turn into UNKNOWN. Default value: 600.

  • sakuli.forwarder.check_mk.spoolfile_prefix - Defines the result file prefix. It can be used to change the default naming convention for the Check_MK output files. Default value: sakuli_suite_.

  • sakuli.forwarder.check_mk.service_description - Defines the service description, which is used within the check result. Default value: ${testsuite.id}. If you want to use a PNP graph template, the service name must begin with sakuli_. Only then the generic PNP template of check_mk for local (=passive) checks will be able to determine sakuli.php as a valid template for this check result. For more information see here.

An example configuration could look like:

sakuli.forwarder.check_mk.enabled=true
sakuli.forwarder.check_mk.spooldir=/var/lib/check_mk_agent/spool
sakuli.forwarder.check_mk.freshness=600
sakuli.forwarder.check_mk.spoolfile_prefix=sakuli_suite_
sakuli.forwarder.check_mk.service_description=My_Custom_Service
Output format template

With the implementation of the Check_MK forwarder a new Jtwig templating mechanism has been introduced in Sakuli, which decouples the output format from the Sakuli binary. This which allows format adaptions to fulfill your needs at any time without installing a new version of Sakuli.

In near time, all other forwarder modules of Sakuli will support the templating feature too.

Sakuli comes with default templates, which are placed in $INSTALL_DIR/config/templates. The default Check_MK templates can be found in a subdirectory check_mk.

For further information how the default template directory can be changed or how the forwarder templates can be customized please refer to Forwarder Templates.

1.4.1.6. Screenshot history

INFO: This section applies to OMD-Labs and the web interface Thruk. To use the screenshot history functionality on other platforms/web interfaces, the steps may vary.

Feature description

In case of an exception, Sakuli takes a screenshot of the current screen and embeds this image into the service output (base64 encoded). The user is able to view the screenshot on the monitoring user interface.

The drawback of this method is that the screenshot only resists in the monitoring core’s memory; as soon as the test recovers, the test output changes back to OK and the image is gone. There are the Nagios/Naemon event logs to inspect former exceptions, but they do not contain the screenshots (fortunately).

With the Screenshot history feature, the monitoring core (Nagios/Naemon/Icinga) fires a event handler script each time the check has a CRITICAL result. The script analyzes the service output, parses the image data and stores it on the local file system within a folder structure published by the OMD site apache process. Sakuli services contain a Thruk action menu which allow the user to see all saved screenshots.

Activating the feature

Use the Makefile located in $OMD_ROOT/share/sakuli/ to enable the feature:

OMD[demo]:~/share/sakuli/setup$ make screenshot_history
cp ./omd/local/lib/nagios/plugins/sakuli_screenshot_eventhandler.sh /omd/sites/demo/local/lib/nagios/plugins/
cp ./omd/etc/nagios/conf.d/sakuli_screenshot_eventhandler.cfg /omd/sites/demo/etc/core/conf.d/
cp ./omd/local/bin/sakuli_screenshot_cleanup.sh /omd/sites/demo/local/bin/
cp ./omd/etc/cron.d/sakuli_screenshot_cleanup /omd/sites/demo/etc/cron.d/
cp ./omd/etc/thruk/ssi/*.ssi /omd/sites/demo/etc/thruk/ssi/
cp ./omd/etc/thruk/thruk_local.d/sakuli_action_menu.conf /omd/sites/demo/etc/thruk/thruk_local.d/
cp ./omd/etc/apache/conf.d/sakuli_screenshots.conf /omd/sites/demo/etc/apache/conf.d/
omd reload crontab
Removing Crontab...OK
Initializing Crontab...OK
omd reload apache
Reloading dedicated Apache for site demo
omd reload core
Reloading naemon configuration (PID: 3511)... OK
Event handler

Now assign the command sakuli_screenshot_eventhandler to all Sakuli services:

define service {
  service_description            example_xfce
  host_name                      sakuli_client
  use                            tpl_s_sakuli_gearman_grafana
  event_handler                  sakuli_screenshot_eventhandler
  event_handler_enabled          1
}

Each time a CRITICAL Sakuli result comes in, the eventhandler will log its actions:

OMD[demo]:$ tail -f var/log/sakuli_screenshot_eventhandler.log
...

Thruk action_menu

Open $OMD_ROOT/etc/thruk/thruk_local.d/sakuli_action_menu.conf and adapt the section <action_menu_apply>. The following example applies the action_menu only on services whose host names begin with "sakuli". See the Thruk documentation for more examples.

# Apply the action_menu on all services of hosts starting with "sakuli"
<action_menu_apply>
     sakuli_history_menu = ^sakuli.*;.+$
</action_menu_apply>

After reloading the web server you should see a small dropdown arrow on each Sakuli service, giving you access to the screenshot history lightbox:

screenshot_hist_action_menu

screenshot_hist_lightbox

The lightbox always shows the last/current screenshot and the error message. To navigate forth/back, use the left/right arrow keys or the buttons in the bottom right corner. Press Esc to close the box again.

Grafana integration

Read the Grafana screenshot annotations section if you want to integrate the screnshots as Grafana annotations.

For PNP4Nagios there is no such feature available.
1.4.1.7. Grafana graphs
This section is written for OMD-Labs environments with InfluxDB/Grafana enabled. It may be useful for others too, but the steps may vary then.

grafana

Feature activation

Check the OMD Labs documentation for infos on how to enable Grafana/InfluxDB.

OMD-Labs already contains a graph template check_sakuli for Histou, the Grafana templating system.
Screenshot annotations

Grafana graphs can also show screenshots of the Screenshot history as anotations.

Execute the Sakuli Makefile to patch the influxDB init script. It will restart InfluxDB and create the Sakuli image database:

OMD[demo]:~/share/sakuli/setup$ make grafana
patch -d /omd/sites/demo -p0 < ./omd/etc/init.d/sakuli_influxdb.patch
patching file etc/init.d/influxdb
omd restart influxdb
Stopping influxdb.....OK
Starting influxdb....OK

In case of an exception, the screenshot history event_handler saves the image on the file system and its path into the InfluxDB database "sakuli" (measurement: images).

Violet vertical lines in the Sakuli graph indicate a saved screenshot. Hover the mouse over the bottom of the line to show the thumbnail:

grafana_screenshot

Click the thumbnail to get the image enlarged.

1.4.1.8. PNP4Nagios graphs
RRD Storage Type

In PNP4Nagios RRD Storage type "MULTIPLE" is of great importance for Sakuli checks, because the number of steps can change by time (=if you are adding/deleting some).

Verify RRD_STORAGE_TYPE in process_perfdata.cfg:

OMD[sakuli]:~$ vim ~/etc/pnp4nagios/process_perfdata.cfg
  RRD_STORAGE_TYPE = MULTIPLE

If this value is "SINGLE" on your system and you do not want to change it globally, use the custom check_command cfg file. PNP4Nagios will then use storage type "MULTIPLE" only for this check_command then:

OMD[sakuli]:~$ cp __TEMP__/sakuli-vx.x.x-SNAPSHOT/setup/nagios/check_sakuli.cfg ~/etc/pnp4nagios/check_commands/
RRD heartbeat

Each RRD file contains a heartbeat value, which determines how much time must pass without any new update, before RRDtool writes an UNKNOWN value (nan) into the data slot (the graph will have a gap then). In PNP4nagios heartbeat is defined at approx. 2 1/2 hours. If your Sakuli check runs only every 2 hours, this value will be fine. But for a 5 minute interval, this is way too long. As a consequence, the graph line will be continuously drawed even Sakuli did no check for two hours. Hence, always make sure to adapt the heartbeat to a value which is slightly higher than the interval of Sakuli checks (and indeally the same as [omd-gearman-freshness_threshold], if you use the gearman receiver):

OMD[sakuli]:~$ cd ~/var/pnp4nagios/perfdata/sakulihost/
# Sakuli check interval: 2 minutes --> RRD heartbeat 3 minutes
OMD[sakuli]:~$ for file in sakuli_e2e_webshop*.rrd; do rrdtool tune $file --heartbeat 1:180; done
install PNP graph template

Copy the PNP4nagios graph template into the templates folder:

OMD[sakuli]:~$ cp __TEMP__/sakuli-vx.x.x-SNAPSHOT/setup/nagios/check_sakuli.php ~/etc/pnp4nagios/templates/
CPU/Memory metrics

If Sakuli reports a long check runtime, it is good to know the CPU/Memory metrics on the Sakuli client machine, because CPU/IO bottlenecks affect Sakuli tests, too.

The following optional enhancement displays the CPU/Memory graph lines of the Sakuli test client in the suite/case graph. By setting custom host macros, the graph template knows where to fetch these data from.

Linux client with CPU check, displayed by a yellow line

PNP graph

add CPU load check (for Linux Sakuli clients)

Add this command to commands.cfg:

define command{
    command_name    check_local_load
    command_line    $USER1$/check_load -w $ARG1$ -c $ARG2$
}

Add this service to services.cfg:

define service {
  service_description            CPU_Load
  host_name                 sakuli_client
  use                            generic-service,srv-pnp
  # if Sakuli checks are running on the same machine (as in the demo VM)
  check_command                  check_local_load!2.5,1.5,1!5,3.5,2
  # if Sakuli checks are running on another host than OMD
  check_command                  check_by_ssh!check_load!2.5,1.5,1!5,3.5,2
}

Add this custom host macros to every Sakuli host in hosts.cfg:

define host {
    …
    _E2E_CPU_HOST                  sakuli_client
    _E2E_CPU_SVC                   CPU_Load_load5
}

Now reload OMD:

omd reload

You should see now the following service on sakuli_client:

PNP graph

The value of _E2E_CPU_SVC and _E2E_MEM_SVC refer to the file name of the corresponding RRD file. CPU_Usage_5 for example means to get the the CPU usage data from $OMD_ROOT/var/pnp4nagios/perfdata/[_E2E_CPU_HOST]/CPU_Usage_5.rrd.
add CPU/Memory usage check (for Windows Sakuli clients)

Install NSClient++ on the Windows client. Then add this command check_nrpe_arg:

    vim ~/etc/nagios/conf.d/commands.cfg

    define command {
      command_name                   check_nrpe_arg
      command_line                   $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ -a $ARG2$
    }

Then add these services to Nagios:

    define service {
      service_description          CPU_Usage
      host_name                    win7sakuli
      use                          generic-service,srv-pnp
      check_command                check_nrpe_arg!CheckCPU!warn=80% crit=90% time=15 time=5 time=1 ShowAll
    }

    define service {
      service_description          Mem_Usage
      host_name                    win7sakuli
      use                          generic-service,srv-pnp
      check_command                check_nrpe_arg!CheckMem!MaxWarn=80% MaxCrit=90% ShowAll type=page type=paged type=physical type=virtual
    }

Add these host macros to every Nagios host where Sakuli checks are defined:

    _E2E_CPU_HOST                  win7sakuli
    _E2E_CPU_SVC                   CPU_Usage_5
    _E2E_MEM_HOST                  win7sakuli
    _E2E_MEM_SVC                   Mem_Usage

Now reload OMD:

omd reload
The value of _E2E_CPU_SVC and _E2E_MEM_SVC refer to the file name of the corresponding RRD file. CPU_Usage_5 for example means to get the the CPU usage data from $OMD_ROOT/var/pnp4nagios/perfdata/[_E2E_CPU_HOST]/CPU_Usage_5.rrd.
XML update delay

As soon as the created services produce perfdata for the first time, their XML file created by PNP4Nagios will also contain the host macros created in the step before. If not, check if XML_UPDATE_DELAY in etc/pnp4nagios/process_perfdata.cfg is set too high.

Change PNP working mode

OMD runs PNP by default in Bulk Mode with NPCD and npcdmod.o. In this mode the Nagios broker module npcdmod.o reads the performance directly from the monitoring core and writes them in var/spool/perfdata. This data are not expandable with custom macros - therefore the mode has to be changed to Bulk Mode with NPCD. (the performance of both modes will be equal).

In this mode the monitoring core itself writes perfdata to the spool directory (instead of npcdmod.o). The format of this data can be freely defined by adapting service_perfdata_file_template. In the following code block you can see that the four custom host macros were added to this template string. Perfdata files are then moved to var/spool/perfdata every 15 seconds by the monitoring core.

Make sure to replace the OMD site name placeholder OMD_SITE with your site name! (in vim type :%s/OMD_SITE/yoursitename/g)
vim ~/etc/nagios/nagios.d/pnp4nagios.cfg

}

Restart the OMD site to unload the npcdmod.o module:

omd restart
Test

First reschedule the CPU/Mem check on the sakuli client. It can take several minutes to store the values in the RRD database. As soon as you can see "real" values in the PNP4Nagios graph of "CPU Load" (instead of “-nan”), restart the Sakuli check. The Sakui graph should now contain also CPU/Memory values.

1.4.1.9. Forwarder Templates

With release 1.1 Sakuli introduced the Jtwig template engine, which is used for generating the output of the Sakuli test suite for certain forwarders. (Currently only the Check_MK forwarder supports Jtwig templates.)

Using templates for the forwarder output makes it possible to easily modify the output of Sakuli and adapt it without the need to release a new Sakuli version.

Here we want to describe how Jtwig is working, how to use a customized template and what you have to pay attention to.

JTwig template

Jtwig is a template engine based on Java, which has a simple and understandable syntax und is easy to use. The following snippet shows an example of a Jtwig template used in Sakuli.

    {% for testStep in testCase.stepsAsSortedSet %}
        , step "{{ testStep.name }}"$whitespace$
        {% if (testStep.state.error) %}
            EXCEPTION: {{ errorMessageCreator.exceptionMessage(testStep) }}
        {% else %}
            over runtime ({{ testStep.duration }}s/warn at {{ testStep.warningTime }}s)
        {% endif %}
    {% endfor %}

The input for this template is the testCase object, which has a set ot test steps. The template iterates over all the steps and prints certain step information based on the state of the test step.

The whole Jtwig feature set is supported and can be used within the Sakuli forwarder. For more detailed information about Jtwig templates, please refer to Jtwig.

Customized Jtwig Functions

Jtwig comes with a list of functions like abs, concat etc, which can be used within a template. In addition to the standard functions, Jtwig supports the implementation and injection of custom functions. Sakuli provides following custom functions:

  • abbreviate - The function abbreviates a certain string to a specified length. The implementation is based on the StringUtils.abbreviate method from the Apache commons library.

  • extractScreenshot - The function extracts the screenshot from a specified test data entity, which contains an exception.

  • getOutputDuration - The function returns the formatted duration for a specified test entity.

  • getOutputState - The function returns the OutputState for a specified SakuliState.

  • isBlank - The function checks whether the specified string parameter is blank.

Please refer to the Sakuli default Jtwig templates, to see the custom functions in action.

Handling of white spaces and new lines

The forwarder implementation provides a special handling of white spaces and new lines within the templates. For this feature the jtwig-spaceless-extension has been used, which comes with a SpaceRemover interface. This has been implemented by the LeadingWhitespaceRemover. The LeadingWhitespaceRemover is configured in the twig template engine and removes all leading whitespaces for every line and all line endings within the template. It can be activated by adding the text snippet or the whole template within the following tags {% spaceless %} and {% endspaceless %}. The LeadingWhitespaceRemover has been introduced, to make the implementation and maintaining of the templates easier.

Since the leading white spaces and the new lines are removed, some special placeholder have been introduced, which are replaced by the real characters at the end of the template generation: * $whitespace$ - the placeholder will be replaced by a real white space. * $newline$ - the placeholder will be replaced by a new line '\n'.

Using a customized templates

Sakuli provides a default template set, which is placed within the templates directory under SAKULI_HOME/config/templates within the Sakuli home folder (e.g. the default Check_MK templates can be found in a subdirectory check_mk).

The property sakuli.forwarder.template.folder defines the path to the main.twig template for the respective forwarder. The default value is set to ${sakuli.home.folder}/config/templates.

Before customizing a default template, it is essential to copy the templates to a new location and configure that location as the template location in Sakuli, otherwise installing a new Sakuli release would overwrite the modified templates within the config directory.

Structure of the default main template

Generally the forwarder is expecting to find a certain template file named main.twig within the configured template directory. The default main.twig template doesn’t contain the whole output, but includes further templates to make the single templates more readable. Since the templates are fully customizable, the user can decide how the templates are structured, whether to use nested templates or to define everything within a single file.

The following snippet shows the default main.twig template provided by Sakuli for the Check_MK forwarder. This template is also showing the use of the spaceless extension and the special character for a new line.

    {% spaceless %}
    {% import 'error_message_creator.twig' as errorMessageCreator %}
        <<<local>>>$newline$
        {% include 'performance_data.twig' %}
        {% include 'short_summary.twig' %}
        {% include 'detailed_summary.twig' %}
        $newline$
    {% endspaceless %}
Supported Forwarder

1.4.2. Continuous Integration

1.4.2.1. Jenkins

Sakuli can also be integrated in continuous integration environments like Jenkins. Documentation is coming in the next time (…have one?)

1.4.3. SQL Database

This page describes how the results of Sakuli can be stored into a MySQL database which can be read by other 3rd party systems.

sakuli-db-schema

Create Sakuli DB

Create the Sakuli database and the DB user:

$ mysql < __TEMP__/sakuli-vx.x.x-SNAPSHOT/setup/database/create_sakuli_database.sql

Create the database user:

$ mysql
  grant ALL on sakuli.* to '__DB_USER__'@'%' identified by '__DB_PASSWORD__';
  flush privileges;
  quit

Check the connection with your favorit SQL tool:

Enable database forwarder

On the Sakuli client you must set the properties for the database receiver. For this, edit sakuli.properties in the folder containing the test suites (you can copy the lines from SAKULI_HOME/conf/sakuli-default.properties):

__INST_DIR__/example_test_suites/sakuli.properties:

# DEFAULT: false
sakuli.forwarder.database.enabled=true

#DEFAULT: mysql
sakuli.forwarder.database.jdbc.driverClass=com.mysql.jdbc.Driver
sakuli.forwarder.database.host=__DB_IP__
sakuli.forwarder.database.port=__DB_PORT__
sakuli.forwarder.database=sakuli
sakuli.forwarder.database.user=__DB_USER__
sakuli.forwarder.database.password=__DB_PW__
Test result transmission

Execute the example test case:

  • Ubuntu: sakuli run INST_DIR/example_test_suites/example_ubuntu/

  • openSUSE: sakuli run INST_DIR/example_test_suites/example_opensuse/

  • Windows 7: sakuli run INST_DIR\example_test_suites\example_windows7\

  • Windows 8: sakuli run INST_DIR\example_test_suites\example_windows8\

The database should now contain the results.

Integration in other tools

You can find queries using the Sakuli DB in /setup/nagios/CheckMySQLHealthSakuli.pm in the extracted Sakuli sources folder.

We are looking forward to reading your story of how you integrated the DB results in your toolchain.

Database cleanup (optional)

Sakuli’s database can get very large over time. Use the following database maintenance script to keep only the most recent data.

Create a crontab entry for a automatic database cleanup of data older than 90 days:

~$ crontab -e
00 12 * * * $SAKULI_HOME/bin/helper/mysql_purge.sh 90 > /dev/null 2>&1

After that, the crontab should be active.

1.5. Developer Documentation

In this section you will find a few helpful documentation for developers who want to contribute.

1.5.1. Installation guide for Sakuli-Developers

  • In order to run Sakuli test cases directly from the IDE, you need to build up a run configuration. For IntelliJ see the predefined run configurations under intellij/runConfigurations

  • classpath of module: sakuli-core

  • working directory: $MODULE_DIR$

  • main class: org.sakuli.starter.SakuliStarter

  • program arguments: [[source]

-run <path to your Sakuli test suite folder> --sakuli_home <path to your "main" folder> --sahi_home <path to your sahi folder>

e.g. for the provided Win7 example use:

-run ../sakuli_test_suites/example src/main/_include ../sahi
  • To run the testng tests correctly and prevent wrong file paths, set the default TestNG config like follow: intellij testng config

Startup error: If you run your Sakuli test the first time, you might get a native library error, caused by Sikuli, saying that it could not find the correct native library to work with. At the same time, Sikuli already tried to fix the problem by modyfing PATH. Solution: Just log out and in again, so that the modified PATH-Variable will be read. Sakuli should start now without any error.
Install JavaFX
  1. Ensure that you have installed the latest JDK-8 version with included JavaFX

  2. Ensure that the system variable java.home points to your JDK directory and includes the file ${java.home}/lib/ext/jfxrt.jar

  3. (optional) Download the JavaFX SceneBuilder for development from Oracle

  4. (optional) Install the SceneBuilder to your IDE:

1.5.2. How to create a new release

  • Check if all features are merged in dev

  • Check if changelog.adoc is correct

(Jenkins CI) Perform a new official release
  1. Go to Jenkins - Sakuli_perform_release and execute the job and set the parameters REL_VERSION and DEV_VERSION

  2. Check if maven artifacts have been deployed at https://labs.consol.de/maven/repository/org/sakuli/

  3. Check the new taged verison on DockerHub with same REL_VERSION for the following images: DockerHub - Sakuli

  4. Test the new docker images as long the sakuli-exampels are not in the automated build

  5. Check te latest documentation is updated at http://consol.github.io/sakuli/.

  6. Make a new GitHub Release:

    • Add sakuli-vXXX-installer.jar and sakuli-vXXX.zip from https://labs.consol.de/sakuli/install/ to a new release XXX

    • Copy the latest changelog to the new release page

    • Check and publish new release

(local) Process a new release with maven

1. Dry-run (if needed)

Generate a new relase over jgitflow-maven-plugin (branch: release/xxx):

    mvn jgitflow:release-start -DnoDeploy=true -DpushReleases=false -DlocalOnly=true

Do a dry-run without deploying and pushing any new files:

    mvn jgitflow:release-finish -DnoDeploy=true -DpushReleases=false -DlocalOnly=true

Delete all local git changes and branches

2. Release

Generate a new relase over jgitflow-maven-plugin (branch: release/xxx):

    mvn jgitflow:release-start

Execute the following commands, to update the Dockerfiles to the new release version at the branch release/xxx .

    docker/update_sakuli_version.sh --new-version $REL_VERSION
    git commit -am "update Dockerfiles to REL-Version v$REL_VERS"

Start the release deploying and pushing any new branches and tags if needed:

    mvn jgitflow:release-finish

Go to the dev branch and adjust the version of the Dockerfiles:

    docker/update_sakuli_version.sh --new-version $DEV_VERS
    git commit -am "update Dockerfiles to DEV-Version v$DEV_VERS"

Push your changes:

git push --all

Finally delete the no longer needed remote feature branch and do the manual release steps from above (after Jenkins job):

git branch -d <branchName>
git push origin --delete <branchName>
Troubleshooting

Re-use a tag

To re-use an already set tag, remove it from git (local and remote):

# delete the tag locally:
git tag -d sakuli-X.X.X`
# push to remote:
git push --delete origin sakuli-X.X.X`

General

  • Check your maven settings in ~/.m2/settings.xml:

  • Ensure that your private key has access rights for user sakuli@labs.consol.de

  • Ensure that your private key is added to ssh-agent: ssh-add <path-to-key>

  • Check proxy settings - the server labs.consol.de must be reachable

  • Ensure that the ConSol-Labs server is configured correctly, see SQL Database

1.5.3. Maven aspects

Following default lifecycle actions are currently used:

Complete build process mvn clean deploy
  1. Compiles the sources with the aspectj-maven-plugin to weave the source code and the dependencies

  2. Executes all unit tests

  3. Executes all integration tests (without UI-Tests)

  4. Adds the built maven artifacts to the local workspace

  5. Builds the sakuli-vX.X.X.zip`and `sakuli-vX.X.X-installer.jar file locally

  6. Deploys the maven artifacts to the local repository

Run unit tests mvn test

Runs all steps until step 2.

Run integration tests mvn verify

Runs all steps until step 3

Install locally mvn install

Runs all steps until step 6

Build a new release

See the instruction: How to create a new release

Special maven profiles

Profiles can be added with option -P, followed by a parameter, e.g.

mvn install -P upload-release
  • upload-release Copies the generated sakuli-zipped-release-vX.X.X.zip, sakuli-vX.X.X-installer.jar file and maven artifacts to the ConSol Labs server. Your private key for the ssh connection have to be configured in maven config file .m2/settings.xml:

Example of Maven config file .m2/settings.xml
    <servers>
        <server>
            <id>labs-consol-sakuli-install</id>
            <username>sakuli</username>
            <privateKey>${user.home}/.ssh/id_rsa</privateKey>
        </server>

        <server>
            <id>labs-consol-sakuli-repository</id>
            <username>maven-repository</username>
            <privateKey>${user.home}/.ssh/id_rsa</privateKey>
        </server>
    </servers>
  • ui-tests Enables the UI based test in phase integration-test in the modul integration-test and java-dsl.

  • generate-manual This profile will generate the AsciiDoc documentation in the module docs-manual, see AsciiDoc documentation aspects.

  • generate-markdown This profile will generate Markdown file in the module docs the file Sakuli API.

To use the profile behind a HTTP/HTTPS proxy, be aware that the following things are configured:

1) include in your $M2_HOME/settings.xml the proxy tag (if needed):

  <proxies>
  <proxy>
      <id>my-proxy-config</id>
      <active>true</active>
      <protocol>http</protocol>
      <host>proxy.company.com</host>
      <port>8888</port>
  </proxy>
  </proxies>

2) configure your system HTTP and HTTPS proxy over Environment (for Ubuntu). Set in bash.rc:

  export http_proxy=http://proxy.company.com:8888/
  export https_proxy=http://proxy.company.com:8888/
  export ftp_proxy=http://proxy.company.com:8888/
  • cl (internal use) This profile will be only to build a custom installer for CL.

Add new artifacts to remote repo

for example for the sahi JARs, more information see: guide-3rd-party-jars-remote.

install to local repo

mvn install:install-file -DgroupId=net.sf.sahi -DartifactId=sahi -Dversion=5.1 -Dpackaging=jar -Dfile=sahi-5.1.jar

mvn install:install-file -DgroupId=net.sf.sahi -DartifactId=ant-sahi -Dversion=5.1 -Dpackaging=jar -Dfile=ant-sahi-5.1.jar

mvn install:install-file -DgroupId=net.sf.sahi -DartifactId=sahi-install -Dversion=5.1 -Dpackaging=zip -Dfile=sahi-install-5.1.zip

install to remote repo

mvn deploy:deploy-file -DgroupId=net.sf.sahi -DartifactId=sahi -Dversion=5.1 -Dpackaging jar -Dfile=sahi-5.1.jar -Drepository=labs-consol-sakuli-repository -Durl=scpexe://labs.consol.de/home/maven-repository/www/htdocs/repository

or copy the local artifacts via SCP:

scp -r ~.m2/repository/net/sf/sahi/sahi/5.1 maven-repository@labs.consol.de:/home/maven-repository/www/htdocs/repository/net/sf/sahi/sahi/5.1

1.5.4. AsciiDoc documentation aspects

Generate AsciiDoc documentation

Execute:

mvn install -f src/docs-manual/pom.xml -P generate-manual

The Asciidoctor-maven-plugin now generates a HTML page and the PDF:

 $ ls src/docs-manual/target/generated-docs/
 $ ls src/docs-manual/target/generated-docs/pdf

Then you can open the file src/docs-manual/target/generated-docs/index.html in your favourite browser.

Upload to GitHub Pages

If you want to update the Github Page consol.github.io/sakuli, just add the profile upload-manual:

mvn install -f src/docs-manual/pom.xml -P generate-manual,upload-manual

OR use the Jenkins CI job Sakuli_CI_update_documentation

Live preview in browser

While writing the documentation it is useful to have a live preview. For this you can do the following:

Start the auto-refresh goal of the Asciidoctor-maven-plugin, which re-creates the html pages as soon as there are changes on the file system:

mvn clean install -f src/docs-manual/pom.xml -P generate-manual-watch

Then use one of the following methods to serve the documentation locally with an ad-hoc webserver:

python -m SimpleHTTPServer (1)
live-server src/docs-manual/target/generated-docs (2)
1 Open a small python adhoc web server on http://127.0.0.1:8000 (manual refresh)
2 Install and open the NPM based "live-server" on http://127.0.0.1:8080; will refresh the broewser window on every page recreation.
Sakuli API generation

Currently there is no fully automated way between the documented Sakuli API in docs/manual/testdefinition/sakuli-api.md and the final docs/manual/testdefinition/sakuli-api.adoc .

Following Steps have to be executed:

1) Generate the sakuli-api.md file Run the maven markdown generation build:

mvn install -f src/docs-sakuli-api/pom.xml -P generate-markdown

The markdown file will be generated under: docs/manual/testdefinition/sakuli-api.md

2) Convert to AsciiDoc

pandoc -s -S sakuli-api.md -t asciidoc -o sakuli-api.adoc

3) Copy & paste the changed content to one of matching the files and maybe adjust heading level to .Class.method():

$ ls docs/manual/testdefinition/sakuli-api*.adoc
docs/manual/testdefinition/sakuli-api.adoc
docs/manual/testdefinition/sakuli-api-application.adoc
docs/manual/testdefinition/sakuli-api-environment.adoc
docs/manual/testdefinition/sakuli-api-key.adoc
docs/manual/testdefinition/sakuli-api-logger.adoc
docs/manual/testdefinition/sakuli-api-mouse-button.adoc
docs/manual/testdefinition/sakuli-api-region.adoc
docs/manual/testdefinition/sakuli-api-testcase.adoc
