Your first TDD experience: Learn refactoring & the Red-Green-Refactor Cycle.
Learn TDD the easy way with a TDD Paint by Numbers session, where the tests are already written for you--you fill in the code and keep it in the confines of the tests. Sessions are continually available in numerous programming languages, and I'll be keeping the katas fresh.
Upcoming sessions: Please check back later
