SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

Manually testing local web applications is slow and inconsistent, especially when verifying UI functionality, capturing screenshots, debugging frontend behavior, or managing multiple local development servers during testing.

Core Features & Use Cases

  • Playwright-Powered Automation: Write native Python scripts to interact with web apps, validate UI elements, capture screenshots, and inspect browser logs for debugging.
  • Automatic Server Management: Use the bundled with_server.py script to automatically start, wait for readiness, and clean up one or more local development servers before running test scripts.
  • Use Case Example: Test a full-stack local app by automatically launching both backend and frontend servers, navigating to the app, validating login functionality, and capturing screenshots of key UI states without manual server management.

Quick Start

Use the webapp-testing skill to validate the user registration flow of your local web app by navigating to the running server, filling out the registration form with test data, and capturing a screenshot of the confirmation page after successful submission.
