This use case is what mixins are for. You don't have to include TestCase in your ancestry until you get to a class which you actually want to run tests. The current rule of loading anything that subclasses TestCase is simple and straightforward. Complicating it to provide a feature which is already available through a widely used standard Python idiom doesn't seem worth while.
