Twelve Years of Go

An automated test suite is table stables. If you can achieve correct, maintainable code better with functional or integration tests than unit tests, you should.

There is no hard technical line between "unit test" and "integration tests", it's a semantic question of how you define your units. Even if do you take a tiny, restrictive definition of your units, you could still use a fake or stub instead of a mock.

To get very specific for Go, we use testify suites, tend to set up fully functional stubs in `SetUp`, and then test cases either use them to verify happy paths, or `s.BreakStep1()` in one test, `s.BreakStep2()` in the next, etc. So in this case we would write a total of five extra lines for the five possible ways to break.

I think that is a fair opinion and my life at work would be better if others shared that opinion. Go however does officially stake out the opposite position: coverage only "counts" if the test is in the same package as the unit under test.
