Comments by "Immudzen" (@Immudzen) on "Add APPROVAL TESTING To Your Bag Of Tricks" video.

Approval testing has been extremely useful for me. We took code that had no testing and added approval tests to the system. Once we did that we refactored piece by piece and added unit tests as we broke things up. As we went we found real bugs and would then discuss fixing them and what impact that would have on usage of the system. We could then fix that bug, update the approval tests, and repeat the process. It worked well and I don't know of any other method that would have worked as well to deal with the spaghetti mess of code.
