Pining Chris based on previous discussion in issue16997 ... Hope that's okay.

I notice that the language in my initial message also conflates error and failure. My apologies on the carelessness.

Just to clarify:


    @unittest.expectedFailure
    def test(self):
        THIS_VARIABLE_IS_UNDEFINED  # ---> NameError


should give: ERROR (errors=1)
currently gives: OK (expected failures=1)


By fixing this, we can help projects to maintain their tests decorated with expectedFailure so that the tests remaining to be meaningful.
