Use Case: Simplified UI Testing

Imagine you want to write UI tests for your application. With XCUITestHelper, you can easily streamline your test code and make it more readable.

import XCTest
import XCUITestHelper

final class MyAppUITests: XCTestCase {
    override func setUpWithError() throws {
        continueAfterFailure = false
    }

    func testExample() throws {
        // UI tests must launch the application that they test.
        let app = XCUIApplication()

        // * Set the app language to English.
        app.setLanguage(to: .english)
        // Do this before launching the app.
        app.launch()

        // * `Wait` for 1 second to continue
        app.wait(for: 1)

        // * Tap a `random` cell in a collection view.
        // Random works with any kind of element, not just buttons.
        app.collectionViews.buttons.random.tap()

        // * Go back to previous screen (NavigationView)
        app.navigateBack()

        // * Tap on the last button
        app.buttons.lastMatch.tap()

        // * Tap on the second button
        app.buttons[1].tap()

        // * Type something, and then clear it.
        let textfield = app.searchFields.firstMatch
        app.type(in: textfield, text: "a", action: .clear)
    }
}

Caveats

• Make sure to handle errors when accessing UI elements.

• Be aware of potential race conditions when waiting for elements to appear.
