The point about coverage results is an important one to understand. Something that I like to say when discussing this with other folks is that while high code coverage does not tell you that you have a good test suite, low code coverage does tell you that you have a poor one. It's one metric amongst many that should be used to measure your code quality, it's not the end-all-be-all.
code coverage is a bad metric either way. soon as it gets mentioned anywhere, an mba manager wants it as close to 100 as possible and goodhart's law kicks in.
it's synonymous with LOC. don't bring it up anywhere.
