UI testing with XCUITest in iOS Swift - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is XCUITest in iOS development?

XCUITest is a framework by Apple used to write UI tests for iOS apps. It simulates user interactions to check if the app behaves correctly.

beginner

How do you launch the app in an XCUITest case?

You create an XCUIApplication instance and call its launch() method to start the app before testing UI elements.

What is the role of XCUIElement in XCUITest?

XCUIElement represents UI elements like buttons, labels, or text fields. You use it to interact with or verify UI components in tests.

intermediate

How can you check if a button exists and is hittable in XCUITest?

Use the exists property to check if the button is present and the isHittable property to check if it can be tapped.

beginner

Why is it important to use accessibility identifiers in UI testing?

Accessibility identifiers uniquely identify UI elements, making tests reliable and less likely to break if the UI layout changes.

Which class do you use to represent the app in XCUITest?

A UIViewController

B XCUIApplication

C XCTestCase

D UIWindow

XCUIApplication represents the app and is used to launch and interact with it in UI tests.

How do you simulate a tap on a button in XCUITest?

A button.press()

B button.select()

C button.click()

D button.tap()

The tap() method simulates a user tapping the button.

What property would you check to verify if a UI element is visible and interactive?

A exists

B isEnabled

C isHittable

D isHidden

isHittable means the element is visible and can be tapped or interacted with.

Why should you assign accessibility identifiers to UI elements?

A To help UI tests find elements reliably

B To disable user interaction

C To change the element's color

D To improve app performance

Accessibility identifiers help tests locate UI elements even if the layout changes.

Which method starts the app in an XCUITest?

A launch()

B run()

C start()

D open()

launch() starts the app so tests can interact with it.

Explain how to write a simple XCUITest that taps a button and verifies a label changes.

Think about the steps a user would do and how to check the result.

Describe why accessibility identifiers are crucial for UI testing and how to set them in your app.

Consider how tests find buttons or labels to tap or check.
