Why Screen Sharing Testing Matters

Screen sharing is a critical feature in many Web apps, enabling users to share their screens with others for presentations, demonstrations, or collaborative work. However, if not properly tested, screen sharing can lead to frustrating user experiences, including poor video quality, audio delays, or complete failures. Common failures in screen sharing include:

• Inability to initiate or join screen sharing sessions
• Poor video or audio quality
• Screen sharing not working across different browsers or devices
• Inability to switch between different screens or windows
• Security issues, such as unauthorized access to shared screens

These failures can have a significant impact on users, leading to wasted time, frustration, and potentially even security breaches.

What to Test

To ensure that screen sharing works correctly, you should test the following scenarios:

• Happy path scenarios:

+ Successful initiation and joining of screen sharing sessions

+ Screen sharing with multiple participants

+ Switching between different screens or windows

+ Sharing specific application windows

• Error scenarios:

+ Attempting to initiate screen sharing without necessary permissions

+ Joining a screen sharing session with an invalid or expired link

+ Screen sharing with a user who does not have the necessary permissions

• Edge cases:

+ Screen sharing with a large number of participants

+ Screen sharing across different time zones or regions

+ Screen sharing with users who have different browser or device configurations

• Accessibility considerations:

+ Screen sharing with users who have disabilities, such as visual or hearing impairments

+ Ensuring that screen sharing controls are accessible via keyboard navigation

+ Providing alternative text for screen sharing elements, such as buttons or icons

Some specific test cases to consider:

• Test that the screen sharing feature works correctly with different browser configurations, such as Chrome, Firefox, and Safari.
• Test that the screen sharing feature works correctly with different device configurations, such as desktops, laptops, and mobile devices.
• Test that the screen sharing feature works correctly with different network configurations, such as Wi-Fi and Ethernet.

Manual Testing Approach

To manually test screen sharing, follow these steps:

1. Setup: Configure your test environment with different browsers, devices, and network configurations.
2. Initiate screen sharing: Use the Web app to initiate a screen sharing session and verify that it works correctly.
3. Join screen sharing: Use a different browser or device to join the screen sharing session and verify that it works correctly.
4. Test screen sharing controls: Verify that screen sharing controls, such as buttons or icons, are accessible and functional.
5. Test error scenarios: Attempt to initiate or join screen sharing sessions with invalid or expired links, or without necessary permissions.
6. Test edge cases: Test screen sharing with a large number of participants, across different time zones or regions, or with users who have different browser or device configurations.

Automated Testing Approach

To automate screen sharing testing, you can use tools and frameworks such as:

• Selenium: An open-source test automation framework for Web applications.
• Playwright: A browser automation framework for Web applications.
• Cypress: A fast, easy, and reliable testing framework for Web applications.

Here is an example of how you can use Playwright to automate screen sharing testing:

const playwright = require('playwright');

// Launch the browser
(async () => {
  const browser = await playwright.chromium.launch();
  const context = await browser.newContext();
  const page = await context.newPage();

  // Navigate to the Web app
  await page.goto('https://example.com');

  // Initiate screen sharing
  await page.click('#initiate-screen-sharing');

  // Join screen sharing
  await page.click('#join-screen-sharing');

  // Verify screen sharing controls
  await page.waitForSelector('#screen-sharing-controls');

  // Close the browser
  await browser.close();
})();

You can also use GitHub Actions to automate your tests and integrate them into your CI/CD pipeline. For example:

name: Screen Sharing Test
on: [push]
jobs:
  build-and-test:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v2
      - name: Install dependencies
        run: npm install
      - name: Run tests
        run: npm run test

How SUSA Tests Screen Sharing Autonomously

SUSA tests screen sharing autonomously using its autonomous QA platform. SUSA uses 10 user personas, including curious, impatient, elderly, adversarial, novice, student, teenager, business, accessibility, and power user, to test screen sharing. These personas catch different types of issues, such as:

• Curious persona: Catches issues related to exploring screen sharing features and controls.
• Impatient persona: Catches issues related to screen sharing performance and latency.
• Elderly persona: Catches issues related to accessibility and usability of screen sharing features.
• Adversarial persona: Catches issues related to security and permissions of screen sharing.

SUSA also uses WCAG 2.1 AA accessibility testing to ensure that screen sharing features are accessible to users with disabilities. Additionally, SUSA uses OWASP Top 10 security testing to ensure that screen sharing features are secure and do not introduce any security vulnerabilities.

By using SUSA's autonomous QA platform, you can ensure that your screen sharing feature is thoroughly tested and works correctly for all users, without having to write any test scripts or maintain a large test infrastructure. You can simply upload your Web app to SUSA and let it do the testing for you.
