What is XCTest?

XCTest is Apple's framework for writing unit tests in Swift and Objective-C. Tests are organized into subclasses of XCTestCase, and individual test methods begin with "test". XCTest integrates with Xcode's Test Navigator for running tests, viewing results, and measuring code coverage against the app's source.
