Web Application Testing

About

This skill provides a specialized toolkit for Claude to interact with, debug, and test local web applications through native Python Playwright scripts. It streamlines the testing lifecycle by managing server environments for both frontend and backend processes, capturing visual screenshots, and inspecting the rendered DOM to identify UI elements reliably. By emphasizing a reconnaissance-then-action pattern and offering robust server management utilities, it allows for reliable automation of complex dynamic web apps while preventing context window pollution.

Key Features

• Automated server lifecycle management for concurrent frontend and backend processes
• Pre-built helper scripts for common element discovery and reconnaissance workflows
• Visual debugging capabilities via full-page screenshots and DOM state inspection
• Network state monitoring to ensure dynamic JavaScript content is fully rendered
• Native Playwright integration for robust, scriptable browser-based testing
• 7,895 GitHub stars

Use Cases

• Debugging UI inconsistencies and verifying responsive layouts via screenshots
• Automated end-to-end testing of local React, Vue, or Next.js applications
• Verifying frontend functionality against local backend APIs in a unified environment
