How do I debug visual issues or failing tests with this skill?

The toolkit allows Claude to capture full-page screenshots and browser console logs, which can be used to identify layout shifts, CSS errors, or JavaScript exceptions.

Can I use this for dynamic Single Page Applications (SPAs)?

Yes, the skill is designed for dynamic apps and follows a specific pattern of waiting for the 'networkidle' state to ensure all JavaScript has executed before interacting with the page.

Does it support testing both frontend and backend simultaneously?

Yes, it can manage multiple servers at once, such as a Python-based API backend and a Node.js frontend, allowing for true integration testing.

How does this skill handle applications that require a running server?

It includes a with_server.py helper script that automatically starts and stops your local development servers (like npm run dev) before and after running tests.

Is Playwright launched in a visible window?

No, for compatibility with terminal-based environments, Playwright is configured to launch in headless mode (chromium) by default.

Seguridad y Pruebas

Automates and tests local web applications using Playwright with integrated server lifecycle management.

Acerca de

This skill provides a comprehensive framework for Claude to perform end-to-end testing and debugging of local web applications. It leverages Playwright for browser automation and includes specialized helper scripts to manage application server lifecycles, whether dealing with simple static sites or complex multi-tier architectures (e.g., separate backend and frontend). By following a structured reconnaissance-then-action pattern, it ensures accurate element discovery and reliable interaction, making it an essential tool for verifying UI behavior, capturing diagnostic screenshots, and analyzing browser logs in a headless environment.
