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.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?
