Running doctests with unittest

[Thomas Heller]

I'm trying to integrate some doctest tests with unittest. The tests
must be exposed as one or more subclasses of unittest.TestCa se, so I'm
collecting them with a call to doctest.DocTest Suite(), and then add them
to a TestCase class I have created.
The tests seem to run, but they always seem to succeed - I have no idea
why. Any ideas?

I can't explain why all the tests seemed to pass, but I tried a
different approach that works.

Once you have a suite object, you just need to run it. The
TextTestRunner works well for that. I got output errors and failures by
doing the following:

if __name__ == '__main__':
import doctest, unittest
suite = doctest.DocTest Suite()
testRunner = unittest.TextTe stRunner()
testRunner.run( suite)
