test-driven-development

Test-driven development (TDD) improves code quality by writing failing tests first, then implementing minimal code to pass them, and refactoring for clarity. This Red-Green-Refactor cycle catches defects early and reduces feedback loops across your team.

Red-Green-Refactor is TDD's core cycle: write a failing test (red), implement the smallest code to pass it (green), then refactor for maintainability (refactor). This disciplined approach ensures tests drive design and prevents over-engineering.

Yes, TDD works with Ruby. This skill guides Red-Green-Refactor cycles and enforces test-first discipline with clear steps and documentation, helping Ruby teams adopt consistent TDD practice and ship reliable software.

Establish consistent TDD practice by following guided workflows with clear steps, roles, and checkpoints. When a task is requested, outline a concrete plan: write failing tests first, implement minimal code, validate with tests, then refactor.

Writing tests first clarifies requirements, prevents over-design, and catches bugs early. TDD reduces defects in the development lifecycle, shortens feedback loops, and creates living documentation of your code's expected behavior.

No. This skill provides guided Red-Green-Refactor workflows with clear documentation and process steps, making it accessible for teams new to TDD. Start by drafting a failing test for a new feature and follow the outlined cycle.
