I highly recommend Josh Kerievsky's "Refactoring to Patterns" as it talks a lot about this aspect. I consider that book one of the jewels of the TDD literature. -Corey

I like Hill & Charlie's answers... I figure when I have a pre-conceived idea for the design, it's because at least some situations have pressures that make the "known" designs a good idea. When I have

I'm not Matteo but I would either first test a score, or for tetris a line match, or for pong the angle of a bounce.

I can heartily recommend reading "Growing Object Oriented Software: Guided by Tests". ( http://www.amazon.com/Growing-Object-Oriented-Software-Guided-Tests/dp/0321503627). It walks you through the

Stefan... TL;DR: Don't sweat it either way, start with your pre-TDD notion, pass a test, and refactor until you can't stand it anymore, and it will work out. For me, starting with

The Apache Tika project turns out to be another good example of a Test Driven Code base. I spent only an hour with it and already I have a fair understanding. I will using as an example good code next

Hi Corey, Thank you for sharing this. I played this kata months ago, but your kata is quite inspiring to me and I see some improvements I can make. I can't wait to replay it. J Regarding the TTP part,

Thanks a lot, Alpar!
