  I'd say it's a tradeoff. If you are entirely driven by tests that include your deps, they will be slow. Unit tests are good at catching basic behavior issues that would show up with an integration test, but it's easier to see the cause. I'm of the opinion that both are needed, but don't put all your eggs in unit tests (they don't need to be perfect). That extra time being spent on integration tests tend to be better for maintaining system health.

    Google's massive distributed build system also runs tests and so most projects run their dependent tests in parallel on thousands of machines.
