I use Test-Driven Development (TDD) every day, and find it very helpful. It can be hard to get to grips with, though. I was pleased to read that acceptance-testing pundit Gojko Adzic had fun with some very strict TDD rules.
Gojko Adzic » Thought-provoking TDD exercise at the Software Craftsmanship conference.
My approach to TDD is really quite similar to these strict rules. I’ll admit that I do (sometmes) cut a few corners. The biggest aid to getting the most from TDD is definately good refactoring tools. Without that the whole thing becomes so much more clumsy.
TDD is very comfortable with Java and Eclipse. Recently I have moved out of that comfort zone into some fairly deep JavaScript work, and really miss the ability to automatically extract or move methods etc.
