SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

TDD enforces a discipline that ensures your codebase evolves from verified behavior, reducing bugs and enabling safer refactors by driving implementation with tests.

Core Features & Use Cases

Enforces the Red-Green-Refactor cycle to guide implementation with failing tests first.
Improves code quality and maintainability through incremental, test-backed changes.
Use cases include feature development, bug fixes, and safe refactoring across typical software projects.

Quick Start

Write a failing test first, then implement the minimal code to pass that test.

FAQPage Schema

How do I implement test-driven development for feature development?▼

Test-driven development for feature development requires writing a failing test first, then implementing the minimal code to pass that test, and finally refactoring progressively to ensure verifiable, maintainable software.

What is the Red-Green-Refactor cycle in unit testing?▼

The Red-Green-Refactor cycle in unit testing is a workflow that guides implementation by first writing a failing test (Red), writing minimal code to pass the test (Green), and then progressively refactoring the codebase.

How do I use TDD for safe refactoring and bug fixes?▼

TDD for safe refactoring and bug fixes enforces discipline by requiring a failing test before coding changes, validating those changes with a green pass to ensure your codebase evolves from verified behavior and reduces bugs.

Does test-driven development work across typical software projects and languages?▼

Yes, test-driven development works across typical software projects and languages by enforcing disciplined unit testing practices, clear naming, and progressive refactoring to drive implementation with tests.

What's the best way to start a tests-first development workflow?▼

The best way to start a tests-first development workflow is to write a failing test first, then implement the minimal code required to pass that test, ensuring incremental, test-backed changes for maintainability.
