Hi all,
I am switching to using the python unittest module for SMTK's python tests. One reason to do this is that test classes can be imported into interactive sessions and debugged.
As a side effect, there is now a new smtk submodule named smtk.testing that contains a function named process_arguments() and a variable named DATA_DIR, to handle fetching command-line arguments before the unittest framework sees them and complains. Use it like so:
import smtk
import smtk.testing
from smtk.simple import *
import unitttest, os
class AnSMTKUnitTest(unittest.TestCase):
def test(self):
# do stuff like:
model = Read(os.path.join(smtk.testing.DATA_DIR, 'foo.brep'))
self.assertTrue(stuff, "Stuff was false")
if __name__ == '__main__':
smtk.testing.process_arguments()
# Now sys.argv is empty and smtk.testing.DATA_DIR is set.
unittest.main()
A full example is in smtk/model/testing/python/integrationMultiSessionDescriptivePhrase.py .
