> They have more code that has tests than their actually running code. I'd say that's very common and not exclusive to some specific project. I made a change of about 30 lines of code recently, and it had 140 lines of tests (and I, by far, do not cover every situation). I think I've rarely encountered well tested pieces of code that were not way smaller than the tests that came with them.
