subclassing from unittest

[Charles Smith]

Hi,

I'd like to subclass from unittest.TestCase.  I observed something
interesting and wonder if anyone can explain what's going on... some
subclasses create  null tests.

I can create this subclass and the test works:

  class StdTestCase (unittest.TestCase):
      blahblah

and I can create this subsubclass and the test works:

  class aaaTestCase (StdTestCase):
      moreblahblah

but if I create this subsubclass (or any where the first letter is
capital):

  class AaaTestCase (StdTestCase):
      differentblahblah

the test completes immediately without any work being done.

I suspect that the answer is in the prefix printed out by the test.  I
have diffed both the long output (tests works, on the left) and the
short output (null test, on the right):

I see an empty test somehow gets sorted to the beginning of the list.
How could that be a result of whether the first letter of the class is
capitalized or not?

Thanks in advance...
