This is a Playwright wrapper that handles the annoying parts of testing local webapps. It includes a server lifecycle manager that can spin up multiple servers (like a backend on 3000 and frontend on 5173) and tear them down cleanly after your tests run. The docs push a "reconnaissance then action" pattern: navigate, wait for networkidle, screenshot or inspect DOM, then write your selectors based on what actually rendered. It's honest about the main footgun, which is trying to grab selectors before JavaScript finishes executing. The helper scripts are designed to stay out of your context window and work as black boxes you call with flags, which is thoughtful if you're using this with an LLM coding assistant.
