IME, if the tests don't fail the first time you run the code, it says that the tests aren't actually hitting the new behavior. (Maaaaybe 1 in 100 times the code is actually right the first time.)
Likewise, if there's no comments on a pull request, it hasn't been read...
I'd have agreed once, but at some point in my life I realized most of my code really was working right the first time, even messy javascript. Anyone else have this experience?
