Write a 3DSlicer UnitTest with QtTesting

1/ Create your XML script

See QtTesting user Wiki

2/ Create a Python script

This Python test will start 3DSlicer and run the previously recorded xml script

Create a file with the following code

   import slicer
   import slicer.testing
   import slicer.util
   filepath = os.environ['SLICER_HOME'] + 'path/to/your/script.xml'
   testUtility = slicer.app.testingUtility()
   success = testUtility.playTests(filepath)
   if success :
       slicer.util.exit(EXIT_SUCCESS)
   else:
       slicer.util.exit(EXIT_FAILURE)

Save to the directory ${Slicer_SOURCE_DIR}/Applications/SlicerApp/Testing/Python/

3/ Add the test in CMake

Edit the file Slicer4/Applications/SlicerApp/Testing/Python/CMakeLists.txt

Add your test at the end of the Slicer_USE_QTTESTING condition:

   if(Slicer_USE_QTTESTING)
     {   
     ...
     slicer_add_python_test(
       SCRIPT pythonScriptName.py
       SLICER_ARGS --launcher-no-splash --qt-testing)
     }

You just wrote a Slicer Unit Test using QtTesting framework !

Create custom translator/player

QTTesting provides us basic translator and player template.
You can use the following command to create those basic files.

Linux	Mac	Windows
You need to open a terminal and go to the Slicer4 source directory. Then type in the terminal: $ cd path/to/Slicer4-Superbuild/CTK-build/QtTesting/Utilities/Scripts $ python TranslatorPlayerWizard.py MY_MODULE_NAME $ cd ../yourClassName/	You need to open a terminal and go to the Slicer4 source directory. Start -> Microsoft Visual Studio 2008 -> Visual Studio Tools -> Visual Studio 2008 Command Prompt Then type in the terminal: $ cd path\to\Slicer4-Superbuild $ python-build\PCBuild\python.exe CTK-build\QtTesting\Utilities\Scripts\ModuleWizard.py MY_MODULE_NAME $ cd ../yourClassName

4 files should have been created !
