SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires playwright, and includes scripts (resource) components.

What problem does it solve? Testing local web applications manually is slow and error-prone, especially when verifying frontend behavior, debugging UI issues, or capturing browser state. This Skill automates browser interactions with Playwright so you can validate functionality, inspect rendered DOMs, and capture screenshots or console logs programmatically. ## Core Features & Use Cases - Server Lifecycle Management: The with_server.py helper starts one or more servers (e.g., backend plus frontend), waits for readiness, runs your automation, and cleans up automatically. - Reconnaissance-Then-Action Pattern: Navigate pages, wait for networkidle, inspect the rendered DOM, and discover selectors before executing actions on dynamic apps. - Browser Evidence Capture: Take full-page screenshots and record console logs for debugging UI behavior. - Use Case: You have a React frontend on port 5173 and a Python backend on port 3000. Use the helper to launch both servers, then run a Playwright script that logs in, clicks through the dashboard, and screenshots the result. ## Quick Start Ask the AI to test your local web app at localhost:5173 by writing a Playwright script that navigates to the page, waits for it to load, and captures a screenshot.

FAQPage Schema
How do I test a local web application with Playwright in Python?

Write a Python script using sync_playwright, launch Chromium in headless mode, navigate to your local server URL, and wait for the networkidle load state before interacting with elements. Use the with_server.py helper if your server is not already running.

How do I run Playwright tests that need multiple servers?

Use the with_server.py helper with repeated --server and --port flags for each server, followed by your automation command. It starts each server, waits for its port to accept connections, runs your script, then terminates all servers.

Why does my Playwright script fail to find elements on dynamic pages?

Dynamic apps render content asynchronously, so inspecting the DOM too early returns incomplete results. Always call page.wait_for_load_state('networkidle') after navigation before querying selectors or taking screenshots.

Can Playwright automate static HTML files without a server?

Yes, Playwright can open local HTML files directly using file:// URLs built from absolute paths. You can then click elements, fill forms, and capture screenshots without starting any web server.

How do I capture browser console logs during Playwright automation?

Register a handler with page.on('console', handler) before navigating. Each console message is passed to your callback, where you can print or collect the message type and text for later analysis.
