Does this skill help with test coverage?

Yes, it defines rules for enforcing an 80% line coverage minimum and tracking branch coverage across various testing environments.

Can I use this for end-to-end testing?

While it prioritizes unit tests (70%), it includes guidelines and ratios for integration (20%) and E2E (10%) testing to ensure a balanced test suite.

What languages does the TDD Mastery skill support?

It currently provides specific patterns and best practices for JavaScript/TypeScript (Jest/Vitest), Python (pytest), and Go.

How does it handle mocking and dependencies?

It provides guidelines to mock at boundaries like APIs and databases, recommending fakes over mocks and asserting on behavior rather than implementation details.

What is the core workflow enforced by this skill?

The skill follows the Red-Green-Refactor cycle: write a failing test first (Red), write the minimum code to pass (Green), and then clean up the code (Refactor).

Implements a disciplined Test-Driven Development workflow using the Red-Green-Refactor cycle across multiple programming languages.

TDD Mastery provides a comprehensive framework for implementing Test-Driven Development (TDD) within Claude Code. It guides users through the essential Red-Green-Refactor cycle, ensuring that every line of production code is backed by a failing test first. The skill includes language-specific patterns for JavaScript (Jest/Vitest), Python (pytest), and Go, while enforcing best practices like the Arrange-Act-Assert pattern, healthy test ratios, and 80% coverage thresholds. It is an indispensable tool for developers aiming to improve code quality, reduce regression bugs, and maintain a high velocity of delivery through reliable automated testing.
