How can I see what the browser is seeing during a test?

The skill includes patterns for taking full-page screenshots and inspecting the rendered DOM state, which are essential for debugging headless sessions.

Can this skill manage multiple servers at once?

Yes, the included server helper script supports launching multiple services, such as a separate frontend and backend, to facilitate full-stack testing.

How does it handle dynamic apps that load content via JavaScript?

The skill implements a best practice of waiting for the 'networkidle' state, ensuring that the DOM is fully rendered before attempting to interact with elements.

Does it support testing static HTML files?

Yes, it can directly read HTML files to identify selectors or use file URLs within Playwright for quick verification without a running server.

Are the browser tests visible while they run?

By default, the skill uses Chromium in headless mode to ensure high performance and compatibility with automated developer workflows.
