Gerard’s book based on the material is now out, and I recommend anyone who is serious about TDD picking up a copy, so you can leverage a significant amount of community learning on how to do TDD. Amazon have not shipped me my copy yet, but fortunately for me Safari already have it, so I can plumb its depths electronically until I can get a copy I can read on the train. The web site is a great advert for the wealth of material that is available there.
I mean it. If you are serious about TDD, or if you have tried it but failed due to the lack of experience in your team, pick up this store of collected knowledge. I expect that pattern names here to become as common currency as Fowler’s Enterprise Application Architecture ones, so you’ll want to be conversant with them so that you know what folks are talking about.
