What is XCUITest?

Swift

Why XCUITest?

Cons

XCTest vs XCUITest

My First XCUITest

import XCTest

class MyFirstTestcase: XCTestCase {
    
    let app = XCUIApplication()

    override func setUp() {
        super.setUp()
        continueAfterFailure = false
        app.launch()
    }

    func testExample() throws {
        app.staticTexts["View Schedule"].tap()
        app.buttons["Finish Game"].tap()
        XCTAssert(app.alerts["You won!"].exists)
        app.alerts["You won!"].buttons["Awesome!"].tap()
    }
    
    override func tearDown() {
        app.terminate()    
    }

}

Demo

XCUITest API's

XCUIApplication
XCUIElement
XCUIElementQuery

Execution Workflow

XCUIApplication

XCUIElementQuery

XCUIElement

XCUIElementQuery

XCUIApplication

Launch App
 Find Elements on Screen
 Interact elements on Screen
Assert expectation
Kill App

API Demo

Waiting Strategy

XCUIElement.waitForExistence(timeout:)

 

XCTestCase.expectation(for:evaluatedWith:handler:) 

XCTestCase.waitForExpectations(timeout:handler:)
Thread.sleep(forTimeInterval:)
expectation(
    for: NSPredicate(format: "exists == true"),
    evaluatedWith: app.buttons["identifier"],
    handler: .none
)

waitForExpectations(timeout: 5)

Gestures

tap()
doubleTap()
twoFingerTap()
tap(withNumberOfTaps:numberOfTouches:)
press(forDuration)
swipeLeft(), swipeRight(), swipeUp(), swipeDown()
pinch(withScale:velocity:)
rotate(_: withVelocity:)
adjust(toPickerWheelValue: 1)



adjust(toNormalizedSliderPosition: 0.5)
