Can I test dynamic web applications with this skill?

Yes, it includes a 'reconnaissance-then-action' pattern and networkidle waiting logic specifically designed to handle JavaScript-heavy dynamic applications.

What browser engine does this skill use for testing?

It uses Playwright's Chromium engine in headless mode for efficient and reliable local web application interaction and verification.

Does Claude need to read the entire Playwright script to run tests?

No, the skill is designed to use scripts as 'black boxes' to save context space, relying on --help flags and command-line execution rather than ingesting large source files.

How does this skill handle local development servers?

It uses a built-in with_server.py script to automatically start and manage the lifecycle of local servers, ensuring they are running before tests begin and closed when finished.

Security & Testing

Automates and tests local web applications using Playwright scripts with built-in server lifecycle management.

About

The Web Application Testing skill enables Claude to interact with, debug, and verify local web applications by executing native Python Playwright scripts. It features a robust server management utility that handles complex setups like simultaneous frontend and backend execution, ensuring tests run in a stable environment. By implementing a reconnaissance-then-action pattern, it allows for intelligent DOM inspection, screenshot capture, and precise selector identification, making it ideal for verifying dynamic UI behavior while minimizing context window usage through black-box script execution.
