What is Cross-Browser Testing?
Cross-browser testing verifies that an application behaves and renders correctly across the browser engines your users actually run—Chromium, Firefox, and WebKit—since layout, JavaScript behavior, and CSS support can differ subtly between them. Catching engine-specific bugs before release prevents the frustrating class of defects that only appear for a fraction of users. Playwright makes this efficient by driving all three engines with one API, so a single recorded flow can be replayed everywhere without rewriting the test for each browser.
