How does it handle external services?

The skill provides specific patterns for mocking external services, including dict-based states for synchronous APIs and queue-based responses for asynchronous APIs.

Does it follow specific TDD standards?

Yes, it implements methodologies based on Kent Beck and Robert C. Martin (Uncle Bob) principles, including the Three Laws of TDD and FIRST principles.

Can it help with bug reproduction?

Absolutely. It enforces a workflow where you must first write a failing test to reproduce the bug before writing any production code to fix it.

What frameworks does TDD Master support?

It automatically detects and provides specific patterns for Pytest and Django, but the core TDD methodology can be applied to any environment or language supported by Claude Code.

What is the 'test-first' approach in this skill?

It follows the Red-Green-Refactor cycle: write a failing test (Red), write the minimal code to pass (Green), and then clean up the code (Refactor).

Security & Testing

Implements rigorous Test-Driven Development workflows using Red-Green-Refactor cycles and industry-standard testing principles.

TDD Master is a specialized Claude Code skill designed to enforce high-quality software engineering through Test-Driven Development (TDD). Based on the principles of Kent Beck and Uncle Bob, it guides developers through the Red-Green-Refactor cycle, automatically detects project frameworks like Pytest or Django, and ensures that every feature or bug fix is backed by reliable, maintainable tests. By prioritizing the 'test-first' approach, this skill helps eliminate regressions, improves code architecture, and maintains a clean codebase through systematic refactoring and strict adherence to the FIRST principles of testing.
