Hi,

First, my congratulations. This book is very helpfull! :D

I have a question about unit test. For example, in chapter 2, where is made a pong game, there's several unit tests. After my game is completed, this units tests will not work any more right? For example, If I want to test the Menu again, I will not be able because I've implemented some game logics in Update method that handles menu selection so, it will not only display my menu but make a selection too. Is that right or I did not understand this?

Thanks a lot!
