Don't know if you are still looking for examples, but I recently came
across a thread in Python-Dev which had an example using unittest:

As written this example failed because TestCase (from django) was based
on unittest2.TestCase, which was not calling super. I understand,
however, that if the mixins were listed before TestCase that it would work.
Hope this helps.
