SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Test-driven development helps ensure code correctness by requiring tests to fail first and guiding implementation through a failing test, then minimal code, and refactoring.

Core Features & Use Cases

  • Red-Green-Refactor cycle to evolve features with confidence.
  • Test-first discipline to prevent regression and clarify requirements.
  • Safe refactoring by keeping tests green after changes.

Quick Start

Write a failing test, then implement the minimal code to pass it, and refactor.

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

Test-driven development ensures code correctness by writing a failing test, implementing minimal code to pass it, and refactoring safely. The red-green-refactor cycle evolves features with confidence by enforcing a test-first discipline that prevents regressions.

How do I start writing tests before coding for a new feature?▼

To start writing tests before coding, write a failing test that defines the desired behavior, then implement the minimal code required to pass that test, and finally refactor while keeping the tests green.

Does test-driven development help with safe refactoring of existing code?▼

Yes, test-driven development enables safe refactoring by keeping tests green after changes. The test-first discipline validates that new code behaves correctly and prevents regressions across software projects during feature evolution.

When should I use a test-first workflow for bug fixes and feature development?▼

You should use a test-first workflow for bug fixes and feature development when you need to ensure correct behavior and prevent regression. Forcing tests to fail before coding clarifies requirements and validates new code deterministically.
