I use tests frameworks all the time. Whether I do TDD or try a code sample. It’s the faster way isn’t it ?
I become a “green addict”. I feel unconfortable when I’m not seeing green dots on my test runner - or when I do not see red dots when I change code (which frightens me much more).
Or why people are giving up on TDD by Uncle Bob Martin.
This post is great source of arguments to explain TDD to your team mate. Also it contains a lot of arguments to convince them to use TDD.
