SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Tests are required to prevent unverified production code and ensure behavior is validated through failing tests before implementation.

Core Features & Use Cases

Red-Green-Refactor workflow with strict test-first discipline.
Applies to new features, bug fixes, and refactors, guiding engineers toward reliable development practices.

Quick Start

Write a failing test for the desired behavior, then implement the minimal production code to make the test pass.

FAQPage Schema

How do I implement test-driven development for new software features?▼

Test-driven development for new features starts by writing a failing test for the desired behavior, then implementing minimal production code to pass it. This enforces strict test-first discipline through the Red-Green-Refactor workflow.

What is the Red-Green-Refactor workflow in software testing?▼

The Red-Green-Refactor workflow is a test-driven development cycle where you write a failing test, implement minimal code to make it pass, and then refactor while keeping the codebase green. It ensures production code is always driven by failing tests.

Can I use test-first development for bug fixes and refactoring existing code?▼

Yes, test-first development applies to bug fixes and refactors across typical software projects. It guides engineers through structured Red-Green-Refactor steps to ensure behavior is validated through failing tests before implementation.

What's the best way to prevent unverified production code from being deployed?▼

The best way to prevent unverified production code is enforcing test-first development. By requiring behavior to be validated through failing tests before implementation, you ensure reliable development practices and guard features with tests.

Do I need specific testing frameworks to follow a strict TDD workflow?▼

No specific testing frameworks are required. The workflow applies across typical software projects by providing structured steps and guardrails to keep development aligned with TDD principles, regardless of your chosen tools.

Why does test-driven development require writing failing tests before implementation?▼

Test-driven development requires failing tests first to ensure production code is driven by actual requirements. This prevents unverified code and validates behavior through the Red-Green-Refactor cycle until the codebase stays green.
