SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

TDD helps teams reduce bugs and rework by forcing test definitions before implementing production code, leading to clearer designs and safer releases.

Core Features & Use Cases

  • Red-Green-Refactor workflow: write a failing test, make it pass, and refactor with confidence.
  • Guardrails for feature development: ensures every change is driven by tests and measurable outcomes.
  • Use Case: when adding a new feature or fixing a bug, define the expected behavior with tests first, then implement only what passes those tests.

Quick Start

Write a failing test for the feature you plan to implement, then run the tests to see the failure and start minimal production code to make them pass.

FAQPage Schema
What is the Red-Green-Refactor cycle in test-driven development?

The Red-Green-Refactor cycle in test-driven development involves writing a failing test, implementing minimal production code to pass it, and refactoring with preserved test results to ensure software quality.

How do I start test-driven development for a new feature?

To start test-driven development for a new feature, write a failing test defining the expected behavior, run it to validate the failure, then implement just enough production code to pass.

Does test-driven development work for fixing software bugs?

Yes, test-driven development works for bug fixes by defining the expected behavior with tests first, then implementing only the production code changes needed to pass those tests.

What is the best way to ensure software quality during feature development?

The best way to ensure software quality during feature development is applying test-driven development guardrails, ensuring every change is driven by tests and measurable outcomes.

Why use test-first development instead of writing tests after implementation?

Test-first development forces you to define expected behavior before writing production code, which prevents over-engineering and ensures every feature has measurable test coverage from the start.
