Testing / Playwright Interview questions

What are the supported browsers in Playwright?

Playwright ships with three browser engines, which together cover almost every major browser a user might have installed.

Engine	Represents
Chromium	Google Chrome, Microsoft Edge
Firefox	Mozilla Firefox
WebKit	Apple Safari

Playwright also supports launching the actual branded builds of Google Chrome and Microsoft Edge (not just the open-source Chromium build) via the channel launch option, which is useful when a test needs to match exactly what end users run in production.

All three engines run consistently across Windows, macOS, and Linux, and Playwright downloads matching pinned binaries for each one so a test behaves the same locally and on CI, rather than depending on whatever browser version happens to be installed on a given machine.
