What is End-to-End Testing?
End-to-end (E2E) testing validates entire user journeys from start to finish—front end, back end, APIs, databases, and integrations all exercised together as a real user would trigger them. It catches the class of defects that unit and integration tests miss: the ones that only appear when components interact. E2E tests give the highest-fidelity confidence that the product actually works, which is exactly why they map so well to recorded user flows. QI turns those flows into clean, self-healing Playwright E2E specs you fully own.
