Author here. I agree with DHH that people have created bad designs in the name of testability. I disagree with his conclusion that TDD should be thrown out, or that slow end-to-end tests are an adequate replacement. By "stop," I meant, "stop programming for a bit and think about a better way to design," not "stop using TDD." (I might agree that TDD is a bad choice for typical Rails apps, though. That's a pretty narrow case, and it says more about Rails than TDD.)
