Mastering Playwright Screenshot on Failure for Reliable UI Testing

Visual artifacts like screenshots and videos serve as living documentation of your test sessions. They allow developers and testers to see what the browser was rendering at the time a failure occurred. When a Playwright test fails, particularly in asynchronous or animation-heavy applications, debugging through logs alone is often insufficient. A Playwright screenshot on failure reveals exact DOM states, rendering glitches, missing elements, or unexpected overlays that caused the test to fail.
