What problem does it solve? Manually verifying frontend behavior of local web applications is slow and error-prone, especially when servers must be started, pages must finish rendering, and selectors must be discovered before any interaction can happen. ## Core Features & Use Cases - Server Lifecycle Management: The scripts/with_server.py helper starts one or more servers (e.g., backend plus frontend), waits for each port to be ready, runs your automation, and cleans up afterward. - Reconnaissance-Then-Action Pattern: Navigate to a page, wait for networkidle, inspect the rendered DOM or take screenshots, then act on discovered selectors. - Ready-Made Examples: Example scripts cover element discovery, static HTML automation via file:// URLs, and console log capture. - Use Case: You are debugging a React app on port 5173. Use the helper to launch the dev server, run a Playwright script that screenshots the dashboard, captures console errors, and clicks through key buttons to verify behavior. ## Quick Start Use the webapp-testing skill to start my local dev server and write a Playwright script that screenshots the homepage and lists all buttons.
