100% coverage?

What's the goal for test coverage?

Test coverage goal cannot be measured by a numeric quantifier. You may have 100% test coverage but yet your code could be broken. Our goal is to cover as much as good tests for the sake of maintainability. So, when writing tests, think of what the future maintainer could do wrong and try to cover them as well as you are covering your existing feature set.
