Delete tests

One of the most important things you can do is move your tests up the abstraction layers and away from unit tests. For lack of a better term, to move to integration tests. End-to-end tests are often too far from the system to easily understand what's wrong when they break, and can overwhelm a development org. Integration tests (or whatever you want to call them) are often the sweet spot: not tied to a particular implementation, able to survive fairly significant system changes, but also easy enough to debug when they break.

Yes, do this. No unit tests, integration only. Your competitors will thank you for this blunder.

Why is it a blunder? Well, you just slowed down your edit-compile-run cycle by about 10x, and debugging when things go wrong (and it's when, not if) by 100-1000 times depending on the complexity of your environment.

Perhaps the answer is "AI will fix it", but we aren't there yet.
