How do I write unit tests with XCTest?

Unit testing in Swift can be efficiently carried out using the XCTest framework. This allows developers to create tests that can validate the behavior of their code, ensuring reliability and catching bugs early in the development process.

Here's a simple example of how to write a unit test in Swift using XCTest:


        import XCTest
        @testable import YourAppModuleName

        class YourTests: XCTestCase {

            func testExample() {
                let result = addNumbers(2, 3)
                XCTAssertEqual(result, 5, "The addNumbers function should return the sum of two numbers.")
            }

            func addNumbers(_ a: Int, _ b: Int) -> Int {
                return a + b
            }
        }
