1. CI/CD Integration

Run tests in headless mode using npx playwright test --headless.

Configure retries (retries: 2) and sharding (--shard=1/3) to speed up parallel execution in pipelines like Jenkins, GitHub Actions.


2. Test Reporting

Generate beautiful HTML reports automatically with Playwright built-in reporter.

After execution, open the report using npx playwright show-report.


3. Trace Viewer for Debugging

Enable trace recording (trace: 'on-first-retry') in Playwright config.

After a failure, view the detailed trace with npx playwright show-trace trace.zip.


4. Visual Regression Testing

Take UI snapshots and compare automatically using:

expect(await page.screenshot()).toMatchSnapshot('expected.png');

Great for detecting UI bugs during development.


5. Performance Measuring

Measure Time to First Byte (TTFB) and Resource Load Times using:

const response = await page.goto('url');
console.log(response.timing());

Or use the browser’s performance API inside page.evaluate.


6. Network Request Mocking

Intercept and mock API responses with page.route().

Useful for testing error conditions, delayed responses, or offline behaviors.


7. Session Management (Authentication Reuse)

Save authentication state (cookies, tokens) to a file (state.json) and load it for other tests.

Avoids repeating login steps in every test case.


8. Handling Multiple Tabs and Contexts

Create isolated browser contexts with browser.newContext().

Handle new tabs/windows by listening to the page event.


9. API Testing with Playwright

Playwright has a built-in APIRequestContext for API testing.

Send API calls, assert responses without opening a browser.


10. Resilient Frameworks (POM + Helpers)

Build frameworks using Page Object Model (POM) + modular helper utilities.

Makes the test code scalable, clean, and easy to maintain.


11. Advanced Locators and Selectors

Use combinations of text, role, ARIA, regex locators to find tricky or dynamic UI elements reliably.


12. Playwright with Java / Other Languages

Playwright supports Java, Python, C#.

Java requires explicit resource management (browser.close()), different from NodeJS’s auto-handling.
