Test-driven development guidance to keep tests focused on observable behavior rather than implementation details, preventing fragile tests that break during refactors and ensuring development proceeds in small, verifiable steps.
Use the tdd skill to guide a red-green-refactor cycle by writing one failing integration-style test for the next behavior, implementing the minimal code to pass, and then refactoring.

To practice test-driven development, write one failing integration test for the next behavior, implement the minimal code to make it pass, and then refactor. This red-green-refactor workflow proceeds in small, verifiable steps to ensure reliable feature delivery.
Vertical slicing in test-driven development means iterating one behavior at a time to build vertical tracer-bullet cycles. This approach avoids horizontal slicing and speculative work by ensuring each cycle limits scope to one failing integration test.
You should use mocking in test-driven development only at system boundaries. Mocking rules prefer integration-style tests through public interfaces to ensure tests remain focused on observable behavior and prevent breaks during refactoring.
Test-driven development improves interface and module design by promoting deep modules, dependency injection, and small surface areas. It includes refactor candidate checklists to guide structural improvements after passing the minimal implementation code.
To avoid horizontal slicing when implementing new features, apply a test-driven development tracer-bullet approach that drives vertical slices. Iterate one behavior at a time using public interfaces to ensure development proceeds in small, verifiable steps.
