Thats pretty amazing actually! While I certainly have seen a fair amount of code that passes (even good) automated testing but fails on validation, it feels somewhat strange but starts to make sense after a bit to value heavy monitoring more.

Good modularization of code I think makes this more possible - the point of a big test suite is to catch unintended consequences of a change, and the less coupling the less likely this is to happen. Stuff like routers, session object and other stateful/lower level logic I'd imagine is more tricky to change without a test suite

Thanks again for the post and the candid answers!
