As web applications become more dynamic, asynchronous, and user-centric, traditional automation tools often struggle to keep up—resulting in flaky tests, complex configurations, and limited cross-browser support.
Playwright, an open-source framework from Microsoft, is purpose-built to address these modern testing challenges. With a single API, it enables end-to-end testing across Chromium, Firefox, and WebKit, while offering advanced features like auto-waiting, trace analysis, parallel execution, and network mocking—all without third-party dependencies.
What makes Playwright truly powerful isn’t just its feature set—but how seamlessly it integrates into real-world testing pipelines. It empowers QA engineers and developers to build fast, reliable, and maintainable automation at scale.
In this blog, we’ll walk through the most impactful Playwright features—explaining what they are, how to use them, and why they matter for your automation success.
Top Playwright Features
1. Test Code Generator and Inspector Tool in Playwright
What Is Playwright’s Test Generator and Inspector?
The Test Generator is a built-in CLI utility that helps you record user actions in the browser and automatically generates corresponding Playwright test scripts. The Inspector allows you to visually debug and explore test runs with real-time highlighting and step navigation.
How to Use Test Generator?
1. Launch Playwright Codegen:
npx playwright codegen (navigate to the URL in the opened browser)
- A browser window opens. Start interacting with the page (click, type, scroll).
- On the side panel, you’ll see auto-generated code in real-time in your selected language.
- Copy or save the script to reuse or customize it further.
How to Use Playwright Inspector?
- Add PWDEBUG=1 when running your test:
For Windows:
set PWDEBUG=1
npx playwright test
For Linux/macOS
PWDEBUG=1 npx playwright test
- The test execution pauses on each step, highlighting the elements on the browser and giving visual feedback.
Why It’s Useful?
- Kickstarts test writing for new pages or flows.
- Helps developers and testers understand locator strategies.
- Visual debugging makes troubleshooting quick and efficient.
2. Using Fixtures in Playwright for Modular and Scalable Test Setup
Playwright’s powerful fixture system allows you to define reusable components for your tests, making your test setup more modular, scalable, and maintainable.
Playwright also comes with several built-in fixtures out of the box, such as:
- page – A single browser tab (most commonly used fixture).
- context – A browser context (isolated session).
- browser – The actual browser instance.
What Are Fixtures in Playwright?
Fixtures are reusable blocks of setup/teardown logic that run before and after each test. They allow for consistent state management, such as creating test data, launching browsers, or initializing page objects.
How to Use Fixtures?
Here’s a simple fixture that creates a test user before a test and deletes it afterward:
import { test as base } from ‘@playwright/test’;
interface TestFixtures {
user: { id: string; username: string; email: string };
authenticatedPage: Page;
}
const test = base.extend<TestFixtures>({
user: async ({}, use) => {
let user;
try {
user = await createUserAPI({
username: `testuser_${Date.now()}`,
email: `test_${Date.now()}@example.com`
});
await use(user);
} finally {
if (user) {
await deleteUserAPI(user.id);
}
}
},
authenticatedPage: async ({ browser, user }, use) => {
const context = await browser.newContext();
const page = await context.newPage();
// Login with the test user
await page.goto(‘/login’);
await page.fill(‘#username’, user.username);
await page.fill(‘#password’, ‘testpassword’);
await page.click(‘button[type=”submit”]’);
await use(page);
await context.close();
}
});
export { test };
Note: Fixture files typically reside in a separate location (like fixtures.ts) to keep your test suite clean, organized, and maintainable.
3. Retrying Failed Tests in Playwright for Stability in CI/CD
While retries can improve test stability in CI/CD by reducing flaky test failures, excessive retries can hide actual application bugs or unstable tests. Use them wisely to ensure you’re not overlooking deeper issues.
What Are Retries in Playwright?
Retries automatically re-run tests that fail due to flaky conditions like network latency, animation delays, or intermittent API issues.
How to Use Test Retries?
Configure retries in playwright.config.ts:
export default {
retries: process.env.CI ? 2 : 0,
};
Or at the test level:
test(‘unstable test’, async ({ page }) => {
// test logic
}).retries(2);
Why It’s Useful?
- Prevents test suite failures due to one-time glitches.
- Improves CI reliability.
- Reduces manual intervention and reruns.
4. Auto-Waiting in Playwright: No More Manual Sleeps
What Is Auto-Waiting?
Playwright automatically waits for elements to be:
- Attached to the DOM
- Visible
- Enabled
- Stable (not animating)
This eliminates the need for adding waitForTimeout, making tests smarter and cleaner.
However, in cases where auto-waiting doesn’t help—such as with custom animations or loading spinners that aren’t part of standard DOM interactions—you should use explicit waits like page.waitForSelector() or page.waitForLoadState() to ensure reliability.
How to Use Auto-Waiting?
You don’t need to do anything special! Playwright handles it internally:
await page.click(‘button#submit’);
Behind the scenes, Playwright checks readiness conditions before performing actions.
Why It’s Useful?
- Reduces flaky tests caused by timing issues.
- Removes dependency on manual waits.
- Simplifies test scripts.
5. Capturing Screenshots and Videos in Playwright on Test Failures
What Is Screenshot and Video Capture in Playwright?
Playwright can automatically take screenshots or record videos when a test fails, helping you visually analyze what went wrong.
How to Capture Screenshots and Videos?
Update playwright.config.ts:
use: {
screenshot: ‘only-on-failure’,
video: ‘retain-on-failure’,
}
Manual Screenshot:
await page.screenshot({ path: ‘error.png’ });
Why It’s Useful?
- Speeds up debugging.
- Provides visual proof of UI errors.
- Improves bug reporting and communication with developers.
6. Cross-Browser Testing in Playwright: Chromium, Firefox, and WebKit
What Is Cross-Browser Testing in Playwright?
Playwright supports testing in Chromium, Firefox, and WebKit—the core engines behind Chrome, Firefox, and Safari—ensuring broad compatibility.
In addition to desktop browsers, mobile emulation is also available via Playwright, allowing you to simulate devices like iPhones and Android phones for responsive and mobile-specific testing.
How to Run Tests Across Browsers?
Add projects in playwright.config.ts
projects: [
{ name: ‘Chromium’, use: { browserName: ‘chromium’ } },
{ name: ‘Firefox’, use: { browserName: ‘firefox’ } },
{ name: ‘WebKit’, use: { browserName: ‘webkit’ } },
]
Run all:
npx playwright test
Why It’s Useful?
- Ensures UI and functionality consistency across all major browsers.
- Detects browser-specific issues early.
- Improves test coverage.
7. Network Interception and Request Mocking in Playwright
What Is Network Interception?
Playwright allows you to intercept network requests and mock responses to test how your application behaves under different backend scenarios.
How to Use Network Interception?
await page.route(‘**/api/data’, route =>
route.fulfill({
status: 200,
contentType: ‘application/json’,
body: JSON.stringify({ id: 1, name: ‘Test Data’ })
})
);
Why It’s Useful?
- Test UI in isolation from backend.
- Simulate error conditions like 500 or timeouts.
- Perform fast, reliable tests without hitting real APIs.
8. Trace Viewer in Playwright: Deep Debugging Made Easy
What Is the Trace Viewer?
Trace Viewer records all test actions (clicks, navigation, DOM snapshots, network activity) and lets you replay them step-by-step to investigate failures.
How to Use Trace Viewer?
Enable trace capture in config:
trace : ‘on-first-retry’
Run:
npx playwright show-trace trace.zip
Why It’s Useful?
- Comprehensive test replay with UI, logs, and network.
- Saves hours of debugging time.
- Useful for collaboration and sharing test runs.
- Traces can be shared with developers or embedded in CI reports, enhancing collaborative debugging.
- Regularly cleaning old traces is important to avoid excessive storage consumption.
9. Built-In Playwright Reporters
How to Use It
Playwright offers a set of built-in reporters to visualize test results in different formats such as list, dot, line, html, json, junit, and allure. These reports help you track test execution, failures, and trends more efficiently.
You can configure reporters directly in your Playwright config file (playwright.config.ts or .js) like this
import { defineConfig } from ‘@playwright/test’;
export default defineConfig({
reporter: [[‘list’], [‘html’, { outputFolder: ‘playwright-report’, open: ‘never’ }]],
});
To generate and open an HTML report after a test run
npx playwright test –reporter=html
npx playwright show-report
You can also integrate third-party reporters like Allure for detailed visual insights
