SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill helps developers adopt a disciplined test-first workflow to reduce late-stage debugging and improve code reliability.

Core Features & Use Cases

Test-list driven planning: start with a prioritized list of tests before coding.
Red-Green-Refactor cycles: execute cycles to progressively implement functionality while ensuring tests pass.
T-Wada guidelines: apply the t-wada style methods for structured, incremental development.
Documentation & progress tracking: maintain a running record of test coverage and refactor decisions.

Quick Start

Draft a test list for the feature, then start the Red-Green-Refactor cycle following the t-wada rules.

FAQPage Schema

What is test-driven development and how does the red-green-refactor cycle work?▼

Test-driven development is a test-first workflow where you write a failing test, implement code to make it pass, and then refactor. This cycle, known as red-green-refactor, progressively builds functionality while ensuring tests pass at each step.

How do I start implementing a new feature using a test-first workflow?▼

To start test-driven development, draft a prioritized test list for the feature before coding. Then, execute red-green-refactor cycles to incrementally implement the functionality while maintaining test coverage and documenting your decisions.

Can I use this test-driven development workflow for bug fixes in large codebases?▼

Yes, test-driven development applies to both new feature work and bug fixes in large codebases. It helps implement disciplined testing incrementally, reducing late-stage debugging and improving code reliability across small to large projects.

What is the t-wada approach to test-driven development?▼

The t-wada approach is a structured, incremental test-driven development method. It enforces creating a comprehensive test list before coding and following strict red-green-refactor cycles to ensure code reliability and systematic progress.

Why should I create a test list before writing code?▼

Creating a test list before writing code enforces test-list driven planning, ensuring you define prioritized test cases upfront. This structured approach prevents scope creep and guides the red-green-refactor cycles for reliable feature implementation.
