Why does the skill recommend using helper scripts as black boxes?

This approach prevents the large source code of automation scripts from cluttering your context window, ensuring the AI focuses on your specific logic rather than boilerplate.

Does it support testing dynamic web applications?

Absolutely. The skill follows a pattern that waits for the networkidle state to ensure all JavaScript is loaded and the DOM is fully rendered before interaction.

Can this skill handle both backend and frontend servers at once?

Yes, the included with_server.py helper script supports managing multiple servers concurrently, allowing you to test full-stack applications locally.

What automation engine does this skill use?

This skill utilizes Playwright, a powerful and modern framework for reliable end-to-end browser automation and testing.

Can I see what the browser is doing during a test?

While it runs in headless mode for efficiency, the skill provides commands to capture screenshots and browser logs to help you debug visual or console errors.
