SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Test-driven development (TDD) reduces regressions by driving design with tests, ensuring that code behavior is verified from the start and guiding safer evolution of the codebase.

Core Features & Use Cases

  • Red-Green-Refactor cycle: write a failing test first, implement the minimal production code to pass, then clean up and improve design.
  • Clear applicability: ideal for new features, bug fixes, and refactors where behavior is critical and quick feedback is valuable.
  • Discipline and safety: enforces testing before production changes, helping catch issues early and document intended behavior.

Quick Start

Write a failing test, then implement the smallest amount of production 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
What is the red-green-refactor cycle in test-driven development?▼

Test-driven development uses the red-green-refactor cycle by first writing a failing test, implementing the minimal production code to make it pass, and then refactoring safely to improve the design.

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

Test-driven development guides bug fixes and refactoring by enforcing the addition of failing tests first to validate the issue, then implementing minimal production code to achieve green tests before refactoring safely.

When should I apply test-driven development workflows?▼

Test-driven development workflows are ideal for new feature development, bug fixes, and refactors where code behavior is critical, quick feedback is valuable, and catching regressions early is required.

Why does test-driven development improve software quality?▼

Test-driven development improves software quality by driving design with tests, ensuring code behavior is verified from the start, enforcing testing before production changes, and reducing regressions through early issue detection.

What is the best way to start writing minimal production code with TDD?▼

Test-driven development starts by writing a failing test that defines the intended behavior, then implementing the smallest amount of production code required to make that test pass before cleaning up the design.

Does test-driven development require external testing frameworks to run?▼

Test-driven development workflows are applied directly within the development process and do not list any external dependencies, meaning no specific testing frameworks are required to enforce the red-green-refactor cycle.
