SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Reducing bugs and misaligned requirements by enforcing a test-first workflow where tests guide implementation.

Core Features & Use Cases

Red-Green-Refactor cycle: write a failing test, implement minimal code to pass, then refactor with confidence.
Strengthens design and safety during feature development, bug fixes, and refactors by preventing untested production code.
Supports teams adopting TDD as a disciplined approach to software quality and maintainability.

Quick Start

Begin by writing a failing test, then implement only enough code to pass, and refactor.

FAQPage Schema

How does test-driven development reduce bugs in software engineering?▼

Test-driven development reduces bugs by enforcing a test-first workflow where you write a failing test before implementation, ensuring requirements are validated before production code is written.

What is the red-green-refactor cycle in TDD?▼

The red-green-refactor cycle in TDD involves writing a failing test, implementing minimal code to pass the test, and then refactoring the code with confidence while maintaining test validation.

How do I start writing tests before code for feature development?▼

To start test-first feature development, write a failing test that defines the desired behavior, implement only enough minimal viable code to pass that test, and then refactor safely.

Can I apply TDD to bug fixes and refactoring existing code?▼

Yes, TDD applies to bug fixes and refactoring by strengthening design and safety, preventing untested production code through disciplined test validation before changing existing software.

Does test-driven development work for team workflows?▼

Test-driven development supports teams by adopting a disciplined approach to software quality, enforcing red-green-refactor cycles and minimal viable code requirements across team workflows.
