Executing the same test suite across several browsers in one run to validate consistent behavior everywhere.

What is Multi-Browser Run?
A multi-browser run executes your tests across Chromium, Firefox, and WebKit—and often multiple viewport sizes—within a single configured run, so one authoring effort validates behavior everywhere your users are. It efficiently surfaces engine-specific rendering and behavior bugs that would otherwise only appear for a subset of users. Playwright's project configuration makes multi-browser runs straightforward, and because QI exports standard Playwright code, a single recorded flow can be replayed across every target browser without rewriting the test.
