I agree, and I think there is an arrogance by those with the view that 'coverage testing is useless' which blinds them to the real purpose of code coverage testing: to tell you what you haven't tested yet. Coverage isn't supposed to tell you anything about the quality of the tests beyond what code simply has never been tested yet. And yet, people seem to think "code coverage testing" means something else entirely. The only purpose for paying attention to coverage metrics, as a manager, is to understand how much more work there is to be done on the tests - or, to determine code paths which never get executed and are therefore dead weight on the project.
