I am trying to use extreme programming for developing Zope application.

However, I have no good idea on how to automate the unit tests for the user interface. There is a Product "ZUnitTest". It is a testing framework based on "PyUnitTest" for Zope.

I have not yet myself experience with it. But the mailing list archives may provide some information... Dieter
