Re: Running doctests with unittest

I'm trying to integrate some doctest tests with unittest.  The tests
must be exposed as one or more subclasses of unittest.TestCase, so I'm
collecting them with a call to doctest.DocTestSuite(), 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.DocTestSuite()
    testRunner = unittest.TextTestRunner()
    testRunner.run(suite)
