SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It guides teams to adopt test-driven development, ensuring that code is driven by failing tests and minimal implementations.

Core Features & Use Cases

  • Red-Green-Refactor workflow: write failing tests, implement just enough code, and refactor to improve design.
  • Guardrails for production code: prevent adding production code without a failing test, promote test naming and scope discipline.
  • Guidance for various scenarios: feature development, bug fixes, and refactoring across languages and projects.

Quick Start

Write a failing test for the desired behavior, implement the minimal code to make it pass, and then refactor for quality

FAQPage Schema
How does test-driven development improve software quality assurance?▼

The red-green-refactor cycle enforces writing a failing test first, implementing minimal production code to pass it, then refactoring for design quality, preventing production code without failing tests.

How do I apply test-driven development for bug fixes and refactoring?▼

Apply test-driven development for bug fixes and refactoring by writing a failing test that reproduces the bug or validates refactored behavior, then iterating minimal code changes until tests pass.

Can I use this test-first workflow across different programming languages?▼

Yes, this test-first workflow guides teams to write tests, run them, observe failures, and iterate across languages and codebases, enforcing test naming and scope discipline regardless of platform.

What is the best way to prevent adding production code without failing tests?▼

The best way to prevent adding production code without failing tests is adopting a strict red-green-refactor workflow, which enforces guardrails against writing implementation before defining expected behavior through tests.

What are the limitations of enforcing a strict red-green-refactor cycle?▼

A limitation of enforcing the strict red-green-refactor cycle is the required discipline to avoid writing production code without failing tests, which may slow initial feature development but ensures long-term quality assurance.
