webapp-testing

To verify live UI behavior, you open the target route in a running dev server using Playwright, inspect the rendered DOM state, capture screenshots, and read console or network logs to confirm the visual result.

During browser testing, you capture console logs and network responses by running throwaway scratch scripts with Playwright that observe the live app, allowing you to collect evidence of client-side rendering behavior without modifying committed tests.

Yes, browser testing supports authenticated routes that require real-browser observation. You can reproduce visual regressions by opening the live app, inspecting what renders dynamically, and capturing screenshots to prove whether a UI change worked.

The best way to inspect DOM state without modifying committed tests is to use throwaway scratch scripts that run Playwright against a live dev server, observing rendered output and capturing review evidence without altering your test suite.

Yes, a running dev server is required for visual regression testing. The process checks the running web app in a real browser to confirm what users actually see instead of inferring behavior from source code alone.

Browser testing requires real-browser observation because client-side rendering, dynamic data, and authentication cause UI changes that must be visually verified. Capturing screenshots and network logs proves whether the live result works before escalating a fix.
