> I think, writing tests improve code coverage? As @OmairK already mentioned, duplicated tests that test the same code path won't increase code coverage. In fact it will make future refactoring harder because you will have to change more than one tests whenever you introduce a behavior change. If a code path can be covered by end to end api test, that should be preferred. It's better to test on expected behavior of the system instead of implementation details. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
