Can I use this for visual regression testing?

Absolutely. The skill prioritizes visual evidence, requiring screenshots or snapshots for UI changes to prove that feature implementation matches user expectations.

When should I choose Chrome MCP over Playwright?

Use Chrome MCP when you need to debug console errors, inspect network requests, or execute custom JavaScript; use Playwright for headless automation, CI/CD pipelines, and cross-browser testing.

Does this skill support desktop-level automation?

Yes, it includes platform detection logic to route tasks to Hammerspoon for macOS or xdotool/ydotool for Linux systems.

How does this skill integrate with TDD?

The skill automatically loads a TDD enforcement layer that requires you to pass through six mandatory gates, including log reading and test-first implementation, before proceeding.

What is the 'Iron Law of Testing' in this skill?

It is a mandatory requirement to write E2E tests for all user-facing features to prove they work for the end-user, preventing common rationalizations for skipping automated verification.

Security & Testing

Automates end-to-end testing and browser debugging workflows with strict TDD enforcement across multiple platforms.

About

This skill serves as a central hub for navigating complex testing environments, enforcing a 'Test-Driven Development' (TDD) protocol that prioritizes user-facing verification over isolated unit tests. It intelligently routes users to the most appropriate platform-specific tools—including Playwright for CI/CD, Chrome MCP for deep browser debugging of network and console logs, and Hammerspoon or Linux utilities for desktop automation—ensuring every feature change is backed by automated evidence and visual snapshots.

Key Features

Intelligent routing between Chrome MCP, Playwright, and desktop automation tools based on environment.
0 GitHub stars
Cross-platform desktop automation support for macOS and Linux (X11/Wayland).
Strict TDD enforcement via the 'Iron Law of Testing' and mandatory six-gate execution protocol.
Deep browser debugging capabilities including console log inspection and network request monitoring.
Visual verification tools for capturing screenshots, snapshots, and GIF recordings of UI interactions.

Use Cases

Debugging complex JavaScript errors or API race conditions in real-time using Chrome MCP.
Automating cross-browser E2E test suites in headless CI/CD environments with Playwright.
Enforcing high-quality release standards by requiring automated evidence for all user-facing UI changes.
