How does this skill prevent skipping tests?

It forces the loading of a TDD skill which contains six mandatory execution gates, including log reading and test-first protocols, that must be satisfied before proceeding.

Does this skill support Linux and macOS desktop testing?

Yes. It features platform detection that routes to Hammerspoon for macOS and either ydotool (Wayland) or xdotool (X11) for Linux desktop automation.

What is the 'Iron Law of Testing' enforced by this skill?

The Iron Law is a non-negotiable requirement to write and pass E2E tests for any user-facing feature. It ensures that components aren't just unit-tested in isolation but actually work for the end-user.

When should I choose Chrome MCP over Playwright?

Use Chrome MCP when you need to debug console errors, inspect API network requests, or record GIFs of interactions. Use Playwright for headless CI/CD execution and cross-browser testing (Firefox/WebKit).

Can I use this for visual regression testing?

Yes, the skill specifically requires documenting visual changes with screenshots or snapshots and provides tools for visual diffing to prove UI integrity.

Security & Testing

Enforces rigorous end-to-end testing protocols and routes tasks to specialized web and desktop automation tools using a TDD-first approach.

The dev-test skill acts as a high-integrity gateway for software quality assurance within Claude Code. It implements the 'Iron Law of Testing,' which mandates automated E2E verification for all user-facing features to prevent regressions that unit tests often miss. The skill dynamically routes developers to the optimal toolset based on the environment: Chrome MCP for deep browser debugging (network/console), Playwright for headless CI/CD and cross-browser suites, or platform-specific utilities like Hammerspoon and xdotool for desktop automation. By integrating mandatory TDD gates, it ensures that tests are written before features and that no critical verification steps are skipped.
