By the way, Dave Hoover and I proposed a workshop for Agile 2009 titled: TDD Ping Pong Match!
It's a new and improved version of the same workshop conducted in Toronto last year at Agile 2008.
Attendees will be entered into a competition where they will pair-program on implementing small software application features following the TDD Ping Pong game rules. Each game will last for a few minutes, and the programmer with the least time driving (i.e. doing the simplest thing that works and coming up with the most tests) will be declared winner. This game is a great opportunity to learn TDD and Pair-Programming effectively and pragmatically. Winners will receive prizes, so sharpen your TDD Ping Pong skills and get ready for Andy and Dave’s challenge!
