Over the years many people have complained about the so-called “religiosity” of some of the proponents of Test Driven Development. The recent brouhaha over TDD has, once again, brought these complaints to the fore. So I thought it would be a good idea to talk about when TDD does not work.

Don't Learn to Code, Learn to Program – But Come Back in 10 Years
