How does it handle dynamic, JavaScript-heavy applications?

It implements a 'networkidle' wait strategy to ensure all network activity has settled and the DOM is fully rendered before attempting to identify selectors or execute actions.

Can I capture visual evidence of test failures?

Yes, the toolkit includes built-in patterns for capturing full-page screenshots and browser logs, making it easier to diagnose UI issues in headless environments.

Do I need to manually configure Playwright for every test?

No, the skill provides standardized patterns and helper scripts designed to be used as black boxes, minimizing boilerplate and keeping your context window focused on logic.

Is it possible to test static HTML files directly?

Yes, the decision tree includes a path for reading static HTML files directly to identify selectors before writing the Playwright automation script.

How does this skill handle multiple local servers?

The skill utilizes a specialized with_server.py helper script that can orchestrate the lifecycle of multiple servers, such as a backend API and a frontend dev server, simultaneously.

セキュリティとテスト

Enables comprehensive testing and interaction with local web applications using Playwright and automated server management.

概要

This skill provides a specialized framework for testing web applications by combining Python-based Playwright scripts with intelligent server lifecycle management. It streamlines the process of launching local servers—including multi-tier architectures with separate frontends and backends—while performing deep DOM inspections. By utilizing a reconnaissance-then-action pattern, the skill ensures that UI interactions are performed on fully rendered states, making it ideal for debugging visual regressions, verifying user flows, and capturing browser-level logs in a local development environment.
