Could you provide more background? How do you avoid that test_base()
runs in TestD1 or TestD2?

To me it sounds like test_base() is actually no test. Hence, I would
rather give it a catchy name like _build_base_cls().  If a method name
does not start with 'test' it is not considered a test to run
automatically.

Does this help?
