"you don’t know the exact answer up front" is misleading in the sense that there is no exact answer to know. In fact, you know and test the exact invariants of the problem which is precisely what testing is all about. So, in that sense the approach is perfectly in line with everything else. It is just that the exact invariants are inconvenient statistical quantities in this case.
