I gave a follow-up talk on unit testing a couple weeks ago, it was really fun because it was my first time participating in mob programming. There were about twenty participants with really diverse backgrounds and programming language experiences. The goal was to output the lyrics for Twelve Days of Christmas by using TDD.

We made a lot of decisions, some by committee and some by praying to the RNG gods. The solution we came to as a group can be seen here. Unfortunately we did not have time for a critical step in TDD: refactoring. I’ll see if I can bring it up for a future talk.
