In your own code, there's nothing to stop you from creating your own interface classes to use in your own tests. But when it comes to interoperating with other people's code, you can't rely on them having inherited from all the classes you want to test for, so the testing approach isn't much use. Unless you require everyone to inherit from a standard set of base classes, and then we're back in Java-land. Anyhow, I've yet to see a case where you really *need* that sort of testing. Whenever someone asks something like "how do I tell whether I've got a sequence or not", usually it's a symptom of poor API design, IMO. -- Greg _______________________________________________ Python-3000 mailing list Python-3000@python.org http://mail.python.org/mailman/listinfo/python-3000 Unsubscribe: http://mail.python.org/mailman/options/python-3000/archive%40mail-archive.com
