XCTest basics (targets, fixtures)

Set up XCTest targets in Swift packages or Xcode projects, write test cases, and manage fixtures with setUp / tearDown .

XCTest intro

Swift uses XCTest for unit testing. Create a test target, subclass XCTestCase, and write methods starting with test.

A test case is a subclass of XCTestCase. Each test method must start with test and use assertions.

import XCTest

final class MathTests: XCTestCase {
    func testAdd() {
        XCTAssertEqual(2 + 2, 4)
    }
}
