Usually the customer signs off on a functional specification but that has nothing to do with the coding style. Jacob makes a very good point that TDD influences coding style, for example by giving a strong motivation to separate computational code from I/O. But that is independent of the external behavior that the customer cares about. -- http://mail.python.org/mailman/listinfo/python-list
