Some information about software testing is just wrong.
I'm not talking about opinions. I have lots of opinions and they differ from other peoples opinions. I'm talking about misinformation and old information that is no longer applicable.

I've ran across a few lateley that I want to address.

All of the following are wrong:


Integrated tests can't work. I can prove it with wacky math.
Tests have to be blazing fast or they won't get run.
TDD is about design, not about testing.
