Fine-grained TDD cycles map each test to an immediate minimal implementation, reducing feedback latency. This enforces a concrete workflow with a clear RED→GREEN cycle, file naming conventions, and documentation-driven planning to ensure traceability for unit development.

The red-green-refactor workflow involves writing a failing RED test, implementing the minimal code to pass it in the GREEN phase, and refactoring. This iterative cycle expands test coverage with small, verifiable steps until all feature tests pass.

Maintain traceability in TDD by applying consistent file naming conventions for tests and implementations. This documentation-driven planning approach ensures each test is explicitly mapped to its corresponding code throughout the development cycle.

This TDD workflow suits unit and feature development where developers iteratively expand coverage. It handles scale by enforcing small, verifiable red-green refactors with explicit file naming, ensuring traceability across multiple fine-grained cycles.

Avoid fine-grained TDD cycles when immediate iterative feedback or traceable unit coverage is unnecessary. If a feature requires broad architectural changes rather than small, verifiable steps, this strict RED→GREEN workflow may introduce unnecessary latency.
