We already have code that does this on top of unittest.
It is part of the logilab.common library. The command is named pytest
and the extension to TestCase is logilab.common.testlib.TestCase. We
have been writing our tests with this since before the nose project
started and never had the time to see what could be merged or if
replacing our stuff with nose would be a better option.
If you want (parts of) it, it is yours. Since we had no contribution
to this code, if you tell us that your aim is to put the code in the
standard library and ask us, we may even change its license (at the
moment, this is GPL).
Hope this helps,
