--- name: xcuitest-skill description: > Generates XCUITest UI tests for iOS/iPadOS apps in Swift. Apple's native testing framework for reliable, fast UI automation. Supports local simulators and TestMu AI cloud real devices. Use when user mentions "XCUITest", "XCTest", "iOS UI test", "Swift test", "XCUIApplication". Triggers on: "XCUITest", "XCTest UI", "iOS UI test", "Swift UI test", "XCUIApplication", "TestMu". languages: - Swift - Objective-C category: mobile-testing license: MIT metadata: author: TestMu AI version: "1.0" --- # XCUITest Automation Skill You are a senior iOS QA engineer specializing in XCUITest. ## Step 1 — Execution Target ``` ├─ Mentions "cloud", "TestMu", "LambdaTest", "device farm"? │ └─ TestMu AI cloud (upload IPA + test runner) │ ├─ Mentions "simulator", "local", "Xcode"? │ └─ Local: Xcode Test Navigator or xcodebuild │ └─ Default → Local simulator ``` ## Core Patterns — Swift ### Basic Test ```swift import XCTest class LoginTests: XCTestCase { let app = XCUIApplication() override func setUpWithError() throws { continueAfterFailure = false app.launch() } func testLoginWithValidCredentials() { let emailField = app.textFields["emailInput"] XCTAssertTrue(emailField.waitForExistence(timeout: 5)) emailField.tap() emailField.typeText("user@test.com") let passwordField = app.secureTextFields["passwordInput"] passwordField.tap() passwordField.typeText("password123") app.buttons["loginButton"].tap() let dashboard = app.staticTexts["Welcome"] XCTAssertTrue(dashboard.waitForExistence(timeout: 10)) } func testLoginWithInvalidCredentials() { app.textFields["emailInput"].tap() app.textFields["emailInput"].typeText("wrong@test.com") app.secureTextFields["passwordInput"].tap() app.secureTextFields["passwordInput"].typeText("wrong") app.buttons["loginButton"].tap() let error = app.staticTexts["Invalid credentials"] XCTAssertTrue(error.waitForExistence(timeout: 5)) } } ``` ### Element Queries ```swift // By accessibility identifier (best) app.buttons["loginButton"] app.textFields["emailInput"] // By label text app.staticTexts["Welcome back"] app.buttons["Submit"] // By predicate app.buttons.matching(NSPredicate(format: "label CONTAINS 'Login'")).firstMatch // By index app.cells.element(boundBy: 0) // Existence check let element = app.buttons["submit"] XCTAssertTrue(element.waitForExistence(timeout: 10)) ``` ### Actions ```swift element.tap() // Tap element.doubleTap() // Double tap element.press(forDuration: 2) // Long press element.typeText("hello") // Type (field must be focused) element.swipeUp() // Swipe element.swipeDown() element.swipeLeft() element.swipeRight() element.pinch(withScale: 2, velocity: 1) // Zoom in element.rotate(CGFloat.pi, withVelocity: 1) // Rotate ``` ### Assertions ```swift XCTAssertTrue(element.exists) XCTAssertTrue(element.isHittable) XCTAssertTrue(element.isEnabled) XCTAssertEqual(element.label, "Expected Label") XCTAssertEqual(element.value as? String, "Expected Value") XCTAssertTrue(element.waitForExistence(timeout: 10)) ``` ### Handling System Alerts ```swift // Auto-handle permission dialogs addUIInterruptionMonitor(withDescription: "Permission Alert") { alert in if alert.buttons["Allow"].exists { alert.buttons["Allow"].tap() return true } return false } app.tap() // Trigger the monitor ``` ### Page Object Pattern ```swift protocol Page { var app: XCUIApplication { get } } class LoginPage: Page { let app: XCUIApplication init(app: XCUIApplication) { self.app = app } var emailField: XCUIElement { app.textFields["emailInput"] } var passwordField: XCUIElement { app.secureTextFields["passwordInput"] } var loginButton: XCUIElement { app.buttons["loginButton"] } var errorLabel: XCUIElement { app.staticTexts["errorMessage"] } func login(email: String, password: String) -> DashboardPage { emailField.tap() emailField.typeText(email) passwordField.tap() passwordField.typeText(password) loginButton.tap() return DashboardPage(app: app) } } ``` ### Anti-Patterns | Bad | Good | Why | |-----|------|-----| | `sleep(5)` | `waitForExistence(timeout:)` | Unreliable | | Element queries without wait | Always `waitForExistence` first | Race conditions | | Hard-coded tap coordinates | Accessibility identifiers | Screen sizes vary | | Testing in one massive method | Small focused test methods | Better isolation | ### TestMu AI Cloud ```bash # 1.
