Overview

Write a 3DSlicer UnitTest with QtTesting

1/ Create your XML script

See QtTesting User

2/ Create a Python script

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

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)
     }

Create custom translator/player

Download this File:TranslatorPlayerTemplate.zip
Unzip the folder
Use the python script TranslatorPlayerWizard.py to create the basic code

 cd path/to/folder/unzip/Scripts
 ./TranslatorPlayerWizard.py yourClassName
 cd ../yourClassName/
