What is the Unit Test Loop?

It is a specialized Claude Code skill that automates the process of identifying coverage gaps, writing focused tests, and verifying improvements in a systematic, iterative cycle.

Can I set a specific coverage target?

Yes, you can use the --target flag (e.g., /ut --target 80%) to tell the skill exactly what coverage percentage you want to achieve before finishing.

How does it handle React Testing Library?

The skill enforces query priorities, such as favoring getByRole over getByTestId, to ensure your tests validate user-facing behavior and accessibility.

Does it support custom test commands?

Absolutely. You can define your specific test suite command using the --test-command flag, such as 'npm run test:unit' or 'yarn test'.

What are background reviewers in this skill?

The skill integrates with background agents to perform code simplification and quality reviews concurrently while you continue with the next testing iteration.

Security & Testing

Automates the iterative cycle of identifying coverage gaps, writing focused unit tests, and maintaining code quality through integrated reviews.

About

The Unit Test Loop skill streamlines the test-driven development (TDD) process by guiding Claude through a systematic workflow to improve codebase reliability. It identifies missing test coverage, implements targeted tests using React Testing Library best practices, and executes mandatory quality reviews via background agents. By focusing on user-facing behavior and maintaining a strict 'one test per iteration' policy, it ensures high-quality, maintainable test suites with clean git histories and verifiable coverage improvements.
