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.

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.
