What problem does it solve? Manually verifying frontend behavior in local web applications is slow and error-prone, and debugging UI issues without browser automation makes it hard to capture screenshots, console logs, and network responses consistently. ## Core Features & Use Cases - Browser Automation Testing: Write and run Playwright tests covering navigation, clicking, form input, waiting strategies, and assertions against local dev servers. - Debugging & Inspection: Capture full-page or element screenshots, listen to console messages and page errors, and intercept network requests with mocked responses. - Use Case: While developing a podcast player web app, use this Skill to write a Playwright test that loads the local dev server, clicks through the UI, asserts the episode list renders, and captures a screenshot to verify the layout. ## Quick Start Use the webapp-testing skill to write and run a Playwright test that opens my local app at localhost:3000 and verifies the homepage title.
