I just took a peice of code with quite good test coverage, and stopped running main a couple of times during the "unit" test run. Coverage plumetted, and I realised how much of the code is still untested. (The code was actually already structured for testing, I just hadn't written them because of that coverage number....) I am still running main, by the way, but that's a different invocation called "system tests" which runs if unit tests pass (and after the coverage report).
