SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Test-driven development ensures software correctness by writing tests before implementation, preventing regressions and guiding design.

Core Features & Use Cases

  • Write failing tests first to capture the expected behavior before coding.
  • Use the RED–GREEN–REFACTOR cycle to drive implementation and refactoring with safety.
  • Reproduce bugs with reproduction tests to validate fixes and guard against regressions.

Quick Start

Write a failing test first to establish the contract, then implement the minimal code to make it pass.

Frequently Asked Questions about test-driven-development

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How does the red-green-refactor cycle work in test-driven development?▼

The red-green-refactor cycle in test-driven development involves writing a failing test first, implementing minimal code to pass it, and then refactoring safely to ensure correct behavior without regressions.

What is the best way to fix bugs using test-driven development?▼

The best way to fix bugs using test-driven development is writing reproduction tests first to validate the issue, then implementing the fix to pass the test and guard against future regressions.

When should I write failing tests before implementation?▼

You should write failing tests before implementation when adding new features, fixing bugs, or refactoring to establish the expected behavior contract and drive software design with safety.

Can I use test-driven development for refactoring existing code?▼

Yes, test-driven development supports refactoring by using the red-green-refactor workflow to drive implementation, ensuring minimal code changes maintain correct behavior and prevent regressions.

What problem does test-first discipline solve in software quality assurance?▼

Test-first discipline in software quality assurance prevents regressions and guides design by ensuring software correctness through writing tests before implementation.
