It's definitely great in theory until you inherit a codebase with no tests, poor documentation, and numerous reported bugs already live in production. Even better if it was written by people hired because they could do other things better than they could code - which looking at some of the unlabeled wiring messes we were left, isn't saying a lot.
Good way to figure out how an unknown code base works is to add unit tests tho
It's also the only way to migrate architecture safely.
