In order to get hooked by TDD it sometimes seems too much effort to setup things, but that should not be the barrier. Along came Google Spreadsheets and I had a no-setup environment, at least for doing katas and showing of the magic of being rewarded with a red box switching to green once I implemented the right thing. I will tell you the story of how I tried to make TDD as simple as possible and how I ended up with Google Spreadsheets and also how this inspired me to build tddbin.com for use at our JSCodeRetreats. I believe it's the red-green cycle that got them hooked. I did it with students and also kids even a manager asked me "why does not everyone program like that?".
