The unit testing section is interesting because I feel like this may not be the perfect approach to them, but it is not a bad method. Too many times I see unit testing being used as the holy grail of debugging and then half of them get ignored because "Oh that's a known issue."

Higher level functional tests are nice for that reason. Yes, they won’t pinpoint a bug instantly but they survive refactors nicely.

If you use micro services properly, unit tests can still call APIs and survive refactors.
