XCTestCase

XCTestCase is a component in software development used to write and run tests for code, particularly in Apple's development environment. It helps developers verify that individual parts of their program work correctly by automatically executing test cases and checking for expected outcomes. Think of it as a quality check: it confirms that features behave as intended, identifies bugs early, and ensures code changes don't break existing functionality. By systematically testing code, XCTestCase supports the creation of reliable, maintainable software.
