 How Do I Perform Cross-Browser Testing with Playwright?

Why Cross-Browser Testing Matters


Modern websites must work consistently across different browsers and devices. In August 2026, Chrome accounted for 69.39% of worldwide browser usage, followed by Safari at 15.83%, Edge at 5.36%, and Firefox at 2.98%. These numbers show why testers should validate applications beyond a single browser.

How Playwright Supports Cross-Browser Testing


Playwright allows students and QA engineers to test applications across Chromium, Firefox, and WebKit, while also supporting branded Chrome and Microsoft Edge configurations and mobile-device emulation.

First, install the required browsers:


npx playwright install

Then configure browser projects in playwright.config.ts:

projects: [
  { name: 'chromium', use: { browserName: 'chromium' } },
  { name: 'firefox', use: { browserName: 'firefox' } },
  { name: 'webkit', use: { browserName: 'webkit' } }
]

Run all browser tests with:

npx playwright test

You can also run a specific browser using --project=firefox.

What Should Students Test?

Educational Students learning automation should practice login forms, navigation, buttons, dropdowns, responsive layouts, pop-ups, file uploads, and critical business workflows across browsers. They should compare failures and understand whether an issue is browser-specific or application-related.
