FULL DISCUSSION
 

I prefer to just think of tests as tests. I also don't often mock classes.

I write tests first to prove what I'm about to code is correct (or occasionally that my mental model in testing doesn't match reality, or the class API sucks).

Typically software is built in layers, so for higher levels, I can write tests assuming the lower levels are tested (because they have tests) and work (because the code runs and does something sensible also).

Not usually important to mock because that's a lot of work that provides little benefit and slows progress. I do mock if it's easy to do (abstract base classes) or very important to hide some super complex/fragile system.

I try to balance forward progress, rather than testing everything, especially important because half the code gets rewritten so much that I'd have to rewrite half the tests. "Just enough tests" is actually therefore better than "everything is tested", which is better than "Not enough or no tests".
