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.

Integration tests and Unit tests are different tools; and each has their place and purpose. Using one "instead" of the other is a mistake.

Wow I hate this dogmatism. It is indeed better to use one instead of the other. Let’s stop pretending all are equally good and we need every type of test.

Sometimes you just don’t need unit tests and it’s okay to admit it and work accordingly.

If you don't write unit tests, how do you know something works? Just manual QA? How long does that take you relative to unit tests? How do you know if something broke due to an indirect change? Just more manual QA? Do you really think this is saving you time?
