Introduction

SikuliXRobotLibrary is a gui recognition testing library for Robot Framework that leverages the SikuliX version 1.1.0 methods.

It is modeled after the Selenium2Library library.

  • More information about this library can be found in the Keyword Documentation_.
  • Installation information is found in the INSTALL.rst file.

Usage

To write tests with Robot Framework and SikuliXRobotLibrary, SikuliXRobotLibrary must be imported into your Robot test suite. See Robot Framework User Guide_ for more information.

Preconditions

SikuliXRobotLibrary supports Jython interpreters supported by the Robot Framework.

SikuliXRobotLibrary depends on a few other Jython libraries, including of course Robot Framework. All dependencies are declared in setup.py.

SikuliX must be installed with the Tesseract based OCR features. When running the sikulixsetup-1.1.0.jar, make sure to select the second and third options.

Installing from source

The source code can be retrieved either as a source distribution or as a clone of the main source repository. The installer requires Jython version 2.7 or newer. Install by running:

jython setup.py install

Note: In most linux systems, you need to have root privileges for installation.

Uninstallation is achieved by deleting the installation directory and its contents from the file system. The default installation directory is [JythonLibraries]/site-packages/robotframework_SikuliXRobotLibrary-1.0.0-py2.7.egg.

Verifying Installation

Once you have installed SikuliXRobotLibrary it is a good idea to verify the installation. To verify installation start jython::

 C:\> jython

and then at the Jython prompt type::

>> import SikuliXRobotLibrary
>>

If the jython command line interpretor returns with another prompt ('>>' as shown above) then your installation was successful.

Troubleshooting Installation

The most common issue with installing SikuliXRobotLibrary is missing dependencies. An error like::

ImportError: No module named sikuli

indicates that you are missing the sikulixapi.jar package. To correct this problem, install the sikulixapi.jar with tesseract then add the following in the environment variables::

  CLASSPATH = <path to sikulixapi.jar>
  JYTHONPATH = <path to sikulixapi.jar>\Lib

Similarly if you receive "No module named ..." error message then you have another missing dependency. To correct, use easy_install to install the missing package.

Running the Demo

The demo directory contains an easily executable demo for Robot Framework using SikuliXRobotLibrary. To run the demo, run::

jybot -d <output directory> -i <tag> <suite directory>

E.g.::

jybot -d C:\SikuliXRobotLibrary\demo\logs -i Demotest C:\SikuliXRobotLibrary\demo\calc_test_suite
Note: C:\SikuliXRobotLibrary\demo\logs will be automatically created upon running the script

ELI5 Installation Instructions (Windows 7 or 8)

  1. Install Java 8.

    Link: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

    i. Run java -version in command prompt, java version should be displayed, otherwise, add C:\Program Files\Java\jre\bin in Environment Variable

  2. Install Jython 2.7:

    Link: http://www.jython.org/downloads.html

    i. Download the installer then make sure to accept the license agreement during installation

    ii. Add 'C:\jython2.7.0\bin' in Environment variables

    iii. Check if jython is installed, run 'jython --version' command in command prompt, if successful, the following will be displayed

      Jython 2.7.0
    
  3. Install Robotframework from the source:

    Link: https://pypi.python.org/pypi/robotframework

    i. Download and extract the rf source (robotframework-2.9.2.tar.gz (md5)) to a local directory

    ii. cd to the extracted directory where setup.py is located

    iii. Open a command prompt and run:

    jython setup.py install
    
    * jybot.bat will be created in C:\jython2.7.0\bin
    * C:\jython2.7.0\Lib\site-packages\robotframework-2.9.2-py2.7.egg will be created
    

    iv. Run jybot --version in command prompt, if successful, the following will be displayed:

    Robot Framework 2.9.2 (Jython 2.7.0 on java1.8.0_60)
    
  4. Install SikuliX v1.1.0.

    Link: https://launchpad.net/sikuli/sikulix/1.1.0

    i. Download sikulixsetup-1.1.0.jar (md5) in a local directory

    • C:\SikuliX1.1.0

    ii. Double-click the sikulixsetup-1.1.0.jar file

    iii. Once the dialog for installation is launched, select options 2 and 3, i.e. Pack 2 and the tesseract (you may opt to install the IDE option 1 later, but backup the sikulixapi.jar first)

    * if sucessful, the sikulixapi.jar will be created (must be 24-25MB in size otherwise, there may be some missing files if a smaller jar file is created)
    
  5. Add CLASSPATH: C:\SikuliX1.1.0\sikulixapi.jar and JYTHONPATH: C:\SikuliX1.1.0\sikulixapi.jar\Lib in Environment Variables.

    i. Right-click > My Computer > Properties > Advanced system settings > Environment Variables

    ii. Click New button. In Variable Name field, type CLASSPATH and in Variable Value, type C:\SikuliX1.1.0\sikulixapi.jar

    iii. Do the same thing for JYTHONPATH

  6. Install SikuliXRobotLibrary from source.

    Link: https://github.com/jaredfin/SikuliXRobotLibrary

    i. Do the following in command prompt:

    cd C:\
    git clone https://github.com/jaredfin/SikuliXRobotLibrary.git
    cd SikuliXRobotLibrary
    jython setup.py install
    
    * see https://github.com/jaredfin/SikuliXRobotLibrary for more installation instructions and troubleshooting
    
  7. Run the demo calculator test suite.

    i. Do the following in command prompt:

    cd C:\SikuliXRobotLibrary
    jybot -d LOGS -i DemoTest demo\calc_test_suite
    
    * if successful, this should run the following test:

RobotFramework Results Log

Additional Notes:

Sikulix's OCR is still not that perfect in recognizing texts yet, the demo test case only includes more than 1 digit on expected results, single digits and repeating digits like 4444 seems to not return any texts when read by the OCR. you may play with the test cases by assigning different values in the arguments of the test cases

SikuliX takes over the mouse pointer and keyboard control, you may opt to setup the scripts in another node in Jenkins then run it remotely.

For capturing, slicing images and calculating the offset values of x, y, w and h, I am using: picpick: http://ngwin.com/picpick

Other similar tools for image capture and offset value calculations respectively are: IrfanView: http://www.irfanview.com/ pixel-ruler online tool: http://www.rapidtables.com/web/tools/pixel-ruler.htm
