Joe White has done a great job posting session notes from TechEd US.

One post that I found interesting was his notes from Roy Osherove's talk "How not to write a unit test".

There was quite a few suggestions in here that resonated with me, such as removing 'new' calls from within your tests into helper methods that create or initialise objects, and some of his thoughts on stubs vs mocks.

An interesting read, easy to skim through. Thanks Joe, and thanks Roy!

(Wish I was there!)
