Introduction to Keyboard Navigation Testing

Keyboard navigation testing is crucial to ensure that Android apps are accessible and usable for all users, including those with disabilities. Inaccessible keyboard navigation can lead to frustration and abandonment of an app. Common failures in keyboard navigation testing include inability to navigate through form fields, inaccessible buttons, and inconsistent navigation order.

What to Test

The following test cases should be included in a comprehensive keyboard navigation testing strategy:

• Happy path scenarios:

+ Successful login using keyboard navigation

+ Completing a registration form using keyboard navigation

+ Navigating through a multi-step checkout process using keyboard navigation

• Error scenarios:

+ Handling invalid input in form fields

+ Recovering from a crashed or unresponsive app during keyboard navigation

+ Dealing with a keyboard navigation loop (e.g., getting stuck in a particular section)

• Edge cases:

+ Navigating through a long list of items using keyboard navigation

+ Handling keyboard navigation in a nested menu or dialog

+ Using keyboard navigation with a physical keyboard connected to the device

• Accessibility considerations for keyboard navigation:

+ Ensuring that all interactive elements are reachable using keyboard navigation

+ Providing a clear and consistent navigation order

+ Implementing accessibility features such as screen reader support and high contrast mode

Manual Testing Approach

To manually test keyboard navigation on an Android app, follow these steps:

1. Connect a physical keyboard to the device: Use a USB or Bluetooth keyboard to simulate keyboard navigation.
2. Launch the app: Start the app and navigate to the desired screen or feature.
3. Use the keyboard to navigate: Use the keyboard to navigate through the app, focusing on the test cases outlined above.
4. Verify the navigation order: Ensure that the navigation order is consistent and logical.
5. Test error handling: Intentionally enter invalid input or simulate a crash to test the app's error handling.
6. Use the app's accessibility features: Enable screen reader support and high contrast mode to test the app's accessibility features.

Automated Testing Approach

Automated testing can be used to supplement manual testing and ensure that keyboard navigation is thoroughly tested. The following tools and frameworks can be used for automated keyboard navigation testing on Android:

• Appium: A popular test automation framework for Android and iOS. Use the sendKeys method to simulate keyboard input.
• Android UI Automator: A framework for automating Android UI interactions. Use the UiDevice class to simulate keyboard input.
• JUnit: A unit testing framework for Java. Use JUnit to write test cases for keyboard navigation.

Example Appium code snippet:

WebElement usernameField = driver.findElement(By.id("username"));
usernameField.sendKeys("username");

Example Android UI Automator code snippet:

UiDevice device = UiDevice.getInstance(getInstrumentation());
device.pressKeyCode(KeyEvent.KEYCODE_DPAD_DOWN);

How SUSA Tests Keyboard Navigation Autonomously

SUSA, an autonomous QA platform, tests keyboard navigation using its 10 user personas, including the accessibility persona and the power user persona. These personas simulate real-world user interactions, including keyboard navigation, to identify issues such as inaccessible buttons and inconsistent navigation order.

The accessibility persona catches issues related to accessibility, such as:

• Inaccessible form fields
• Inconsistent navigation order
• Lack of screen reader support

The power user persona catches issues related to power user interactions, such as:

• Inability to navigate through a long list of items using keyboard navigation
• Handling keyboard navigation in a nested menu or dialog

SUSA's autonomous testing approach ensures that keyboard navigation is thoroughly tested, providing a comprehensive report of issues and recommendations for improvement. By integrating SUSA into the CI/CD pipeline using GitHub Actions or the CLI tool, developers can ensure that keyboard navigation is tested automatically with each build, reducing the risk of inaccessible or unusable apps.
