Pair Programming is often talked about, but probably not put into practice as much as it could be. Why? It's a difficult skill to master, and often tedious because both members of the pair want to have the keyboard more than half of the time.<br/><br/> Test Driven Development (TDD) is also a difficult skill to acquire, perhaps because it seems easier to "just go ahead and write the code."<br/><br/> This session illustrates the basics of both Pair Programming and TDD by demonstrating the development of a sample application from the ground up, following the rules of the Pair Programming TDD Game, originally developed by Brad Wilson and Peter Provost of Microsoft Corporation.<br/><br/> The game goes beyond the more well-known "ping-pong", and is a fun way to keep both members of a pair engaged. After this session, you'll want to play the game with your own team.
