Since I was doing nothing else on Monday, after the blog post below I spent a couple of hours going through the work in Visual Studio.

While I am still not sold on the concept of the tests driving the development process, it does make you consider your class design from the point of view of it's consumers.  Also the screencast did help bring some clarity to practical test design with NUnit, which is something I strugled with earlier.

My next problem with it:  How do we manage the problem that arises from programmers testing their own input validation for example?

Also the MVP pattern was easier to implement than it looked on DNR TV.  I look forward to watching the episode dedicated to it.
