Not so simple: I have tests that do nothing besides build objects.  If 
building the objects raises no errors the test passed.

Although, for the benefit of empty tests not passing I could add a 
do-nothing assert:

   self.assertTrue(created_obj)

(it's a do-nothing because if the object wasn't created the test would 
have already failed).
