What are some disadvantages of code coverage as a measure for how well a system or product is tested? (three answers)

It does not ensure that the most important or highest risk areas of the code are being exercised by tests

It could create incentives to write tests that simply increase code coverage, rather than tests that find bugs without increasing code coverage
