I'm a fan of PHPUnit code coverage reports. And with this sentence I can
see a lot of the developers out there shiver, because they are of the
opinion, that code coverage reports for unit tests are nonsense and cannot
give you any hint on the quality of a test suite. I see it a bit
differently. Surely, a high code coverage rate of a test suite does never
indicate, that code is well tested (if you have not written the code and
tests yourself). But the other way around works: A small code coverage
rate definitly means, that the test suite is not sufficient. But let me
dig a bit deeper into code coverage and what it gives you.
