Webapp Testing

If you need to test web apps with Playwright but don't want to manually wrangle server startup and shutdown, this handles the lifecycle for you. The with_server.py helper spins up one or more servers, waits for them to be ready, runs your automation script, then tears everything down cleanly. Works for both static HTML and dynamic apps. The decision tree is handy: it pushes you to wait for networkidle before inspecting the DOM, which saves you from chasing phantom elements that haven't rendered yet. The main value is treating common workflows as black box scripts instead of copying boilerplate into your context window every time.
