> "Striving for 100% test coverage is nonsense"

100% coverage of what exactly? Tests that go through all your lines of code without testing any of the logic, is useless. If you want to be thorough, you need to do mutation testing, which is a system that tests the quality your unit tests by mutating your logic (changing a > for >=, a + for -, etc) and then expects at least one test to fail. If no test fails, that piece of logic wasn't tested.

Without that, it's entirely possible your high code coverage doesn't actually test anything meaningful. Also, this sort of logic is exactly the kind of stuff you want to unit test. All the standard plumbing boilerplate code is not something that needs to be unit tested. The logic does.
