Introduction to Video Calls Testing

Testing video calls on Web apps is crucial to ensure a seamless user experience. Video calls are a critical feature in many Web applications, including social media, conferencing, and customer support platforms. When video calls fail, it can lead to frustrated users, lost business, and a damaged reputation. Common failures in video calls include poor video quality, dropped calls, and issues with audio or video synchronization.

Test Cases for Video Calls

The following test cases should be considered when testing video calls on Web apps:

• Happy path scenarios:

+ Successful video call initiation and termination

+ Video and audio streaming without interruptions

+ Screen sharing and annotation functionality

+ Multiple participant video calls

• Error scenarios:

+ Video call failure due to poor network connectivity

+ Audio or video stream interruption

+ Error handling for camera or microphone access denied

+ Call dropping due to server-side issues

• Edge cases:

+ Video call with multiple participants and varying network conditions

+ Video call with participants using different browsers or devices

+ Video call with screen sharing and annotation enabled

• Accessibility considerations:

+ Closed captions and subtitles for audio and video streams

+ High contrast mode and color blindness support

+ Keyboard navigation and screen reader compatibility

+ Audio description for visually impaired users

Manual Testing Approach

To manually test video calls on Web apps, follow these steps:

1. Test environment setup: Ensure a stable and consistent test environment with a reliable internet connection.
2. Test cases execution: Execute the test cases outlined above, using different browsers, devices, and network conditions.
3. Test data collection: Collect test data, including video and audio quality metrics, error logs, and user feedback.
4. Test results analysis: Analyze test results to identify issues and areas for improvement.

Example test case:

### Test Case: Successful Video Call Initiation and Termination
1. Launch the Web app in a browser.
2. Initiate a video call with another user.
3. Verify that the video call is established successfully.
4. Verify that video and audio streams are transmitted without interruptions.
5. Terminate the video call and verify that the call is ended successfully.

Automated Testing Approach

To automate video calls testing on Web apps, use tools and frameworks such as:

• Selenium WebDriver: For automating browser interactions and simulating user actions.
• Playwright: For automating browser interactions and simulating user actions, with a focus on modern web applications.
• WebRTC: For testing WebRTC-based video calls and ensuring compatibility with different browsers and devices.

Example automated test case using Playwright:

// Import required modules
const { test, expect } = require('@playwright/test');

// Define test case
test('Successful video call initiation and termination', async ({ page }) => {
  // Launch Web app in browser
  await page.goto('https://example.com');

  // Initiate video call
  await page.click('text=Start Video Call');

  // Verify video call establishment
  await expect(page.locator('text=Video Call Established')).toBeVisible();

  // Verify video and audio streams
  await expect(page.locator('video')).toBeVisible();
  await expect(page.locator('audio')).toBeVisible();

  // Terminate video call
  await page.click('text=End Video Call');

  // Verify video call termination
  await expect(page.locator('text=Video Call Terminated')).toBeVisible();
});

Autonomous Testing with SUSA

SUSA tests video calls autonomously using its 10 user personas, including:

• Curious: Tests video call initiation and termination, and explores different video call features.
• Impatient: Tests video call performance under poor network conditions, and verifies error handling.
• Elderly: Tests video call accessibility features, including closed captions and high contrast mode.
• Adversarial: Tests video call security, including WebRTC protocol vulnerabilities and cross-site scripting (XSS) attacks.

SUSA's autonomous testing capabilities include:

• Flow tracking: Tracks video call flows, including login, registration, and call initiation.
• Coverage analytics: Provides per-screen element coverage and untapped element lists, ensuring comprehensive testing.
• Cross-session learning: Gets smarter about the Web app with each test run, adapting to changing functionality and features.

Example SUSA test case:

### Test Case: Video Call Accessibility
1. Launch Web app in browser using SUSA's **Elderly** persona.
2. Initiate video call and verify closed captions and high contrast mode.
3. Verify keyboard navigation and screen reader compatibility.
4. Analyze test results and identify areas for improvement.
