If a Swift module is compiled with “testing enabled” it allows us to import that module using the @testable annotation to alter the visibility of our code. Classes and their methods that are marked as internal or public become open , which allows subclassing and overriding in tests.

What is the difference between XCTest and XCUITest?

While XCTest is designed for white-box testing, XCUITest is for black-box testing that doesn’t have access to API and data of the app being tested. You can write test codes using Swift or Objective-C. With the XCode 7 version, this testing framework comes fully integrated with IDE.

What is the benefit of using xctest?

XCTest facilitates your ability to write tests at different levels of abstraction. A good testing strategy combines multiple types of tests, to maximize the benefits of each. Aim for a “pyramid” distribution of tests, as shown in the figure below.

What are test assertions in the xctest framework?

Use the Test Assertions in the XCTest framework to compare the behavior of the code you exercise in the Act phase with your expectations of what should happen. Any assertion whose condition is false causes a test to fail. The resulting test method looks like this example:
