I don't take testing advice from anyone who uses generic terms like "test coverage". Test coverage is a complex subject, but without a basic understanding, tests can create a false sense of security. Saying something like "100% coverage" means almost nothing to anyone that understands testing. This is a worthwhile read: https://en.wikipedia.org/wiki/Code_coverage https://en.wikipedia.org/wiki/Code_coverage Without formal methods, software will realistically never be 100% tested. But don't worry, your hardware isn't either!
