> That said, I generally prefer test harnesses to unit tests[0]. That's a strange redefinition of harness. The larger-scoped tests are more often called integration or even system tests. And while I'm here, those are slow tests that are harder to debug and require more maintenance (often maintenance of an entire environment to run them in!). Unit tests are closer to what they test, fast, and aren't tied to an environment - they can be run on every push.
