Will it help me test private methods?

The skill generally redirects testing toward the public interface. If a private method is complex enough to require its own tests, it will suggest extracting that logic into a new, testable unit.

What happens if I ask to write tests after I've already written code?

The skill will identify that the RED phase was skipped, write tests to capture the current behavior, and then guide you through refactoring opportunities to improve the design.

Does this skill support BDD (Behavior-Driven Development)?

Yes, it maps BDD's Given-When-Then vocabulary to TDD's Arrange-Act-Assert structure, maintaining the same core discipline of testing behavior rather than implementation.

How does this skill handle slow integration tests?

It analyzes the test suite for I/O-heavy unit tests and recommends moving them to the integration layer or using in-memory fakes and test containers to remove non-determinism.

Guides developers through the Red-Green-Refactor discipline to build robust, behavior-driven software with optimal test coverage.

The TDD Master skill transforms Claude into an expert practitioner of Test-Driven Development, enforcing a strict workflow that prioritizes behavioral specifications over implementation details. It guides you through the full lifecycle of writing a failing test, implementing minimal code to pass, and performing structural refactoring. By leveraging the testing pyramid and Arrange-Act-Assert patterns, this skill ensures your test suites remain fast, maintainable, and decoupled from internal logic, ultimately leading to cleaner architecture and fewer regressions.
