Sad that you gave zero history of TDD -- it is a fun story

Kent Beck is worth a quick mention in my humble opinion.

Java people will know him as the creator of JUnit. Before JUnit he wrote a similar framework for SmallTalk and honestly didn’t know if it was that ‘great’ or ‘helpful’ for others.

Great chat from Kent. The first 5 minutes are a lot of fun. Kent Beck on creating JUnit - YouTube
