What problem does it solve?
Guides developers to consistently apply test-driven development, turning feature ideas into validated, maintainable code through a clear Red-Green-Refactor workflow.
Core Features & Use Cases
- Red-Green-Refactor cycle: write one failing test, implement just enough code to pass, then refactor and verify with tests.
- Plan-driven testing: follow plan.md style test instructions to organize tests and expectations.
- Quality-focused workflow: commit small, explainable changes after each stage to maintain traceability and reduce risk.
- Principles in practice: enforce one test per RED, keep methods small, and perform structured refactors to preserve behavior while improving structure.
- Use cases: ideal for introducing new features in a codebase or replacing brittle implementations with test-driven replacements.
Quick Start
Start by writing one failing test for your feature, implement just enough code to pass, then refactor and commit after each step.
