This blog and some of the comments below are just crap. If you haven't TDDed before (for a non trivial project) you simply don't know what you are talking about, and it's apparent in your ignorant opinions.

Sorry if that's a bit harsh but I'm tired of seeing these posts by people who don't get it.

I don't get quantum physics, that doesn't mean I'm going to write an blog "when quantum physics fails"

If you don't understand something... Learn about it, practice it, then criticize its actual flaws.

Don't just get frustrated at something and claim its crap. Because its clear to those of us that do understand it, that you are talking crap
