Test-Driven Development FAQs

Question 1

What does the Test-Driven Development skill for Claude Code do?

Accepted Answer

This skill enforces a strict Red-Green-Refactor cycle, requiring Claude to write a minimal failing test before any production code is implemented. It ensures that all behavior is verified and that code is built specifically to meet defined requirements.

Question 2

When should I use this Claude Code skill?

Accepted Answer

You should use this skill during new feature development, bug fixing, or refactoring. It is essential whenever you need high confidence in code correctness and want to prevent regressions through automated testing.

Question 3

How does this skill improve my AI-assisted coding workflow?

Accepted Answer

It eliminates over-engineering by focusing on the 'Minimal Code' principle and forces the AI to discover edge cases early. By watching tests fail first, you gain documented proof that the AI-generated solution actually solves the intended problem.

Question 4

What happens if code is written without a test first?

Accepted Answer

This skill follows the 'Iron Law': no production code without a failing test first. If implementation code is written prematurely, the skill mandates deleting it and starting over to ensure the integrity of the TDD process.

Question 5

Can this skill handle complex scenarios like mocking and dependency injection?

Accepted Answer

Yes. The skill provides specific strategies for handling mocks, identifying TDD anti-patterns, and managing complex testing scenarios to ensure the resulting architecture is clean, decoupled, and easy to maintain.
