That's right. But coming up with the very tests it tests was an act of representing what happened visually so I could look for problems, categorize them and come up with tests. It took a very long time to feel comfortable that I caught everything. Now if we change it around, I'd have to go through the process again, if you follow my logic.

It certes depends on what we change though. Just changing the directions a bit probably means the tests are sufficient. Changing the logic in any way would possibly be impetus for further examination.
