I don't think unit tests are that helpfull in this case. Unit tests help you in finding out there is a bug, they don't help that much in tracking down a bug. I for some reason a person is reading over the difference between sumLongName and someLongName and doesn't notice the different spelling in his source a unit test won't be of much help. -- Antoon Pardon -- http://mail.python.org/mailman/listinfo/python-list
