SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Ensures software teams follow a test-first workflow, surfacing requirements early by writing failing tests before production code, reducing defects and guiding clean design.

Core Features & Use Cases

  • Enforce the RED-GREEN-REFACTOR cycle for every feature
  • Promote measurable quality through incremental, test-driven changes
  • Facilitate safer refactoring by maintaining a robust test suite

Quick Start

Write a failing test first, run it to confirm failure, implement the minimal production code to pass, and refactor for readability.

FAQPage Schema
How does test-driven development improve software quality and reduce defects?

Test-driven development enforces a test-first workflow that surfaces requirements early by writing failing tests before production code, reducing defects and guiding clean design.

What are the steps to apply the red-green-refactor cycle for feature development?

The red-green-refactor cycle requires writing a failing test first, running it to confirm failure, implementing minimal production code to pass, and executing a dedicated refactor step for readability.

When should I use test-first development for bug fixes and refactoring tasks?

Test-first development applies to bug fixes and refactoring tasks by requiring explicit failing tests before changes, maintaining a robust test suite that facilitates safer refactoring.

What is the best way to enforce TDD best practices across a software team?

Enforcing TDD best practices requires explicit failing tests, minimal production code to pass, and a dedicated refactor step to complete the cycle for every feature.

Does test-driven development work without external testing frameworks or dependencies?

Test-driven development can be applied without specific external dependencies, as the workflow requires writing explicit failing tests and minimal production code to pass.
