Looking at Apple's documentation such as https://developer.apple.com/documentation/xctest/xctestcase/understanding_setup_and_teardown_for_test_methods and many another unit testing with XCTestCase examples, you can see that by convention, in `setUp` and `tearDown` methods, there's always a call to super. Looking at the ObjC version of XCTestCase, these calls are not annotated with the call to `super` being required.When creating a new project with Xcode 10.1, the Unit Test template file doesn't have the call to super. What's the best practice? What's the right thing to do here?
