||We are lucky to have a preview of a chapter that explains writing customer tests using this framework. I like the chapter because it uses dialogs to give us a feel for the division of responsibilities between developers and customers. It also shows off how the framework's exception handling makes test-first programming easy.
The final book will be available from Prentice-Hall this summer and will be called Extreme Software Engineering, A Hands-On Approach by Daniel H Steinberg and Daniel W Palmer.
DanielSteinberg has also written a great piece on the framework for O'Reiley which is cited in FitInTheNews.
