These days, test___all__ checks that everything in __all__ exists in
standard library modules. It is also possible for individual module
tests to include a check that goes the other way along the lines of:

def test_all_is_complete():
  known_private = {"known", "unexported", "names"}
  expected_public = (k for k in mod.__dict__ if k not in known_private
and not k.startswith("_"))
  self.assertEqual(set(mod.__all__), expected_public)

Cheers,
Nick.
