Yeah, debugging tests is an important part of test driven development.
You also have to be careful. Some tests are for me to debug my code and aren’t part of the ‘contract’.
But on the other hand, it’s really nice. If I spend a couple of hours debugging actual code and come out of the process with internal tests, the next time it breaks, the new tests make it much easier to identify what broke. Previously, that would have been almost wasted effort, you fix it and just hope it never breaks again.
