FYI: Google will not allow me to post the slides for Jim McMaster's talk yesterday. Jim sent me a few pointers that point to additional material on Test-Driven Design.
First: Dave Astels book: http://www.amazon.com/Test-Driven-Development-Practical-Guide-Coad/dp/0131016490
Second: A talk that Dave Astel gave on something called Behavior-Driven Development:
I hope you enjoyed Jim's talk and thanks to Jude Allred for making the connection and inviting Jim to speak to us!
