# SHAPER unit test system
# How to use:
# INCLUDE(UnitTest)

# ADD_UNIT_TESTS(TestUndoRedo.py
#                TestResultBody.py)
# or
# SET(PROJECT_UNIT_TESTS
#     TestUndoRedo.py
#     TestWhatever.py  
#    )
# ADD_UNIT_TESTS(${PROJECT_UNIT_TESTS})
#
# Where "TestUndoRedo.py" and "TestResultBody.py" are names 
# of python test scripts in the "./Test" directory.
# This macro will add "Subproject_" as prefix and 
# remove ".py" for the test name automaticaly. 
# 
# Start building of the "RUN_TESTS" project in the Visual studio
# or run "make test" on linux stations to start the testing procedure.
