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.

Web Application Testing

Catalog modification: source-review-first and state-based waits; server helper bounds/cleanup updated.

To test local web applications, write native Python Playwright scripts.

Helper Scripts Available:

scripts/with_server.py - Manages server lifecycle (supports multiple servers)

Inspect helper source, project scripts and lifecycle hooks before execution. Use --help only after review; even help is code execution. These helpers are convenience scaffolds, not an execution sandbox.
