What is XCUItest?

Key Features of XCUItest

1. Integration with Xcode: XCUItest is integrated into Xcode, Apple’s development environment, making it easy to write, run, and manage tests.
2. Accessibility Identification: It uses accessibility identifiers to locate and interact with UI elements, promoting good accessibility practices.
3. Automation: Automates user interactions like taps, swipes, and text entry, enabling thorough and repetitive testing.
4. Parallel Testing: Supports running tests on multiple devices simultaneously, speeding up the testing process.

Setting Up XCUItest

1. Create a New Xcode Project: Open Xcode and create a new iOS project. Choose a template, such as “Single View App,” and configure your project settings.
2. Add a UI Testing Target:
   • Go to your project settings in Xcode.
   • Click the “+” button at the bottom of the target list.
   • Select “iOS UI Testing Bundle” and click “Next.”
   • Name your testing target (e.g., “MyAppUITests”) and finish the setup.
3. Configure the Testing Target:
   • In the newly created testing target, open the MyAppUITests.swift file.
   • Import the XCTest framework and your app’s module.

Writing Your First XCUItest

• Add Accessibility Identifiers: In your main app target, assign accessibility identifiers to the UI elements you want to interact with. For example, in ViewController.swift:

@IBOutlet weak var myLabel: UILabel!
@IBOutlet weak var myButton: UIButton!

override func viewDidLoad() {
    super.viewDidLoad()
    myLabel.accessibilityIdentifier = "myLabel"
    myButton.accessibilityIdentifier = "myButton"
}

• Write the Test: In the MyAppUITests.swift file, write the test method:

import XCTest

class MyAppUITests: XCTestCase {
    
    override func setUpWithError() throws {
        continueAfterFailure = false
        let app = XCUIApplication()
        app.launch()
    }

    override func tearDownWithError() throws {
        // Code to execute after each test method
    }

    func testButtonTapChangesLabelText() throws {
        let app = XCUIApplication()
        let button = app.buttons["myButton"]
        let label = app.staticTexts["myLabel"]
        
        // Ensure the initial state is correct
        XCTAssertEqual(label.label, "Initial Text")
        
        // Perform the button tap
        button.tap()
        
        // Verify the label text changes
        XCTAssertEqual(label.label, "Button Tapped")
    }
}

• 1. Run the Test:
     • Select the MyAppUITests scheme.
     • Press Command-U to run the tests.
     • Xcode will build your app, launch it in the simulator, and execute the test.

  - main
  - test
    - java
      - com
        - yourpackage

Writing Your First Unit Test

public class Calculator {
    public int add(int a, int b) {
        return a + b;
    }
}

import static org.junit.Assert.assertEquals;
import org.junit.Test;

public class CalculatorTest {
    @Test
    public void testAdd() {
        Calculator calculator = new Calculator();
        int result = calculator.add(2, 3);
        assertEquals(5, result);
    }
}

• Explanation:
  • @Test annotation marks the testAdd method as a test case.
  • assertEquals is used to assert that the expected value (5) matches the actual value returned by the add method.

Writing Tests with Mockito

public class UserService {
    private UserRepository userRepository;

    public UserService(UserRepository userRepository) {
        this.userRepository = userRepository;
    }

    public User getUserById(int id) {
        return userRepository.findById(id);
    }
}

import static org.mockito.Mockito.*;
import static org.junit.Assert.*;
import org.junit.Before;
import org.junit.Test;
import org.mockito.Mock;
import org.mockito.MockitoAnnotations;

public class UserServiceTest {

    @Mock
    private UserRepository userRepository;

    private UserService userService;

    @Before
    public void setUp() {
        MockitoAnnotations.initMocks(this);
        userService = new UserService(userRepository);
    }

    @Test
    public void testGetUserById() {
        User mockUser = new User(1, "John Doe");
        when(userRepository.findById(1)).thenReturn(mockUser);

        User user = userService.getUserById(1);
        assertEquals("John Doe", user.getName());
    }
}

• Explanation:
  • @Mock annotation creates a mock instance of UserRepository.
  • MockitoAnnotations.initMocks(this) initializes the mock objects.
  • when(...).thenReturn(...) sets up the behavior of the mock object.
  • assertEquals asserts that the returned user’s name matches the expected value.

Best Practices for Video Recording in Tests

1. Control Recording Duration: Avoid recording excessively long videos to save storage space and make reviewing easier. Use the withTimeLimit option to control the recording duration.
2. Store Videos Effectively: Save the video files with descriptive names, including test case identifiers and timestamps for easy retrieval.
3. Regular Clean-up: Regularly clean up old video files to manage storage space efficiently.
4. Review and Analyze: Frequently review recorded videos to identify and address flaky tests or intermittent issues.

Conclusion

Why Record Test Sessions?

Before diving into the technical details, let’s understand the benefits of recording test sessions:

1. Debugging: Video recordings help identify visual bugs that might not be evident from logs alone.
2. Documentation: Recordings provide a clear documentation of test cases and their outcomes.
3. Collaboration: Sharing recordings with team members or stakeholders facilitates better communication and understanding of issues.
4. Regressions: Video evidence can be used to quickly spot regressions by comparing current test runs with previous ones.

Tools and Prerequisites

To record iOS Appium test sessions, you’ll need the following tools:

1. Appium: The automation framework itself.
2. Xcode: Apple’s integrated development environment for macOS.
3. ffmpeg: A powerful multimedia framework to handle video recording.
4. QuickTime Player: For manual recording (if needed).
5. Node.js: Required for Appium installation.

Ensure you have the following prerequisites:

• A macOS machine with Xcode installed.
• An iOS device or simulator.
• Appium server and client set up on your machine.
• Homebrew (for installing ffmpeg).

Setting Up Video Recording

Step 1: Install ffmpeg

First, install ffmpeg using Homebrew. Open Terminal and run:

brew install ffmpeg

Step 2: Configure Appium

Ensure Appium is installed and configured correctly. If you haven’t installed Appium, use the following command:

npm install -g appium

Start the Appium server with:

appium

Step 3: Start Recording Using ffmpeg

Use ffmpeg to record the iOS simulator screen. Here’s a command to start recording:

ffmpeg -f avfoundation -i "<device_index>" -r 30 -pix_fmt yuv420p -t <duration> output.mp4

• <device_index>: The index of your iOS device. You can find this by running ffmpeg -f avfoundation -list_devices true -i "".
• <duration>: The duration for which you want to record the video (in seconds).

Step 4: Integrate Recording into Appium Test Scripts

You can automate the start and stop of video recording within your Appium test scripts. Below is an example in Java:

import io.appium.java_client.MobileElement;
import io.appium.java_client.ios.IOSDriver;
import io.appium.java_client.remote.MobileCapabilityType;
import org.openqa.selenium.remote.DesiredCapabilities;

import java.net.URL;
import java.io.IOException;

public class AppiumTestWithRecording {
    private static Process ffmpegProcess;

    public static void startRecording() throws IOException {
        String[] command = {"ffmpeg", "-f", "avfoundation", "-i", "<device_index>", "-r", "30", "-pix_fmt", "yuv420p", "-t", "60", "output.mp4"};
        ffmpegProcess = new ProcessBuilder(command).start();
    }

    public static void stopRecording() {
        if (ffmpegProcess != null) {
            ffmpegProcess.destroy();
        }
    }

    public static void main(String[] args) {
        DesiredCapabilities caps = new DesiredCapabilities();
        caps.setCapability(MobileCapabilityType.PLATFORM_NAME, "iOS");
        caps.setCapability(MobileCapabilityType.PLATFORM_VERSION, "14.4");
        caps.setCapability(MobileCapabilityType.DEVICE_NAME, "iPhone 12");
        caps.setCapability(MobileCapabilityType.APP, "/path/to/your/app.app");
        caps.setCapability(MobileCapabilityType.AUTOMATION_NAME, "XCUITest");

        try {
            startRecording();

            IOSDriver<MobileElement> driver = new IOSDriver<>(new URL("http://localhost:4723/wd/hub"), caps);

            // Your test steps here
            MobileElement loginButton = driver.findElementByAccessibilityId("loginButton");
            loginButton.click();

            // Additional test steps...

            driver.quit();
            stopRecording();
        } catch (Exception e) {
            e.printStackTrace();
            stopRecording();
        }
    }
}

Best Practices for Video Recording in Tests

1. Start/Stop Recording Programmatically: Automate the start and stop of recordings within your test scripts to ensure consistent capture.
2. Manage Storage: Regularly clean up old recordings to manage storage space effectively.
3. Use Descriptive File Names: Name your recording files with timestamps or test case identifiers for easy identification.
4. Monitor Performance: Ensure that recording does not significantly impact the performance of your test runs. Adjust frame rate and resolution settings if necessary.
5. Review Recordings: Regularly review recordings to identify flaky tests or intermittent issues that logs alone might not reveal.

Conclusion

Video recording of iOS Appium testing sessions is a powerful feature that enhances the debugging, documentation, and collaboration aspects of mobile test automation. By following the steps outlined in this blog, you can set up and integrate video recording into your Appium test scripts, ensuring a more robust and informative testing process. Whether you are capturing visual evidence of test failures or documenting test runs for stakeholders, video recordings are an invaluable addition to your mobile testing toolkit.
