Why we write unit test cases?

Developers write unit tests for their code to make sure that the code works correctly. This helps to detect and protect against bugs in the future. Sometimes developers write unit tests first, then write the code. This approach is also known as test-driven development (TDD).

What is the difference between XCTest and XCUITest?

XCUITest is a User Interface (UI) testing framework launched by Apple in 2015 as a major update to enhance testing capabilities. It is built on top of XCTest – a test framework that is integrated within Apple’s Xcode IDE.

What is XCTAssert in unit testing?

XCTAssert is one of a family of asserts for unit testing from the XCTest framework, and should only be present in Unit Test Targets (i.e. not in your application code). If the assert fails, it does not terminate the execution of the test harness or hosting application, but records and reports the failure.
