SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve? Verifying frontend behavior of local web applications requires manually starting servers, opening browsers, and inspecting rendered pages, which is slow and error-prone. This Skill automates browser interaction, UI debugging, screenshot capture, and console log collection using Playwright. ## Core Features & Use Cases - Automated Browser Testing: Write native Python Playwright scripts to navigate pages, click elements, fill forms, and verify frontend functionality. - Server Lifecycle Management: The scripts/with_server.py helper starts one or more servers (backend plus frontend), waits for port readiness, runs your automation, and cleans up. - Reconnaissance-Then-Action Pattern: Inspect the rendered DOM after networkidle, discover selectors from buttons, links, and inputs, then execute actions against the live state. - Use Case: You are debugging a booking form on a local dev server. Launch the server with the helper, capture a full-page screenshot, dump console logs, and confirm the form submits correctly. ## Quick Start Ask the AI to test your local web app at localhost:5173 by taking a screenshot and listing all buttons and form fields on the page.

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

Write a Python script using sync_playwright, launch Chromium in headless mode, navigate to your localhost URL, and wait for networkidle before interacting. Use the with_server.py helper to start your dev server automatically before the script runs.

How to run Playwright tests against a dev server that is not running?▼

Use the with_server.py helper script with --server and --port flags to start your server, wait for the port to respond, then execute your automation script. It supports multiple servers, such as a backend on port 3000 and a frontend on port 5173.

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 exactly as you would against a hosted page.

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

Element lookups fail when the DOM is inspected before JavaScript finishes rendering. Always call page.wait_for_load_state('networkidle') after navigation, then take a screenshot or dump page content to discover the actual rendered selectors.

How do I capture browser console logs during Playwright automation?▼

Register a handler with page.on('console', handler) before navigating, and append each message to a list. After the session, write the collected messages to a log file for debugging frontend errors.
