SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Test-driven development (TDD) ensures you write failing tests before implementing production code, reducing bugs by design.

Core Features & Use Cases

  • Red-Green-Refactor cycle: write a failing test, implement the minimal code, then refactor.
  • Early defect detection: catches issues at the moment of change.
  • Behavior-driven development alignment: tests serve as living documentation aligning with requirements.

Quick Start

Write a failing test for a small feature, then implement just enough code to make it pass, and repeat.

FAQPage Schema
How does the red-green-refactor cycle work in test-driven development?

Test-driven development reduces bugs by enforcing a failing-first test cycle before writing production code. It catches issues at the moment of change and aligns behavior-driven tests with living documentation, ensuring higher code quality during feature implementation and bug fixes.

How do I apply test-driven development to fix bugs and implement features?

To apply test-driven development, write a failing test for the specific bug or small feature, implement just enough code to make it pass, and repeat. This enforces mandatory test execution before coding across all behavior-heavy software changes.

When should I use test-driven development for refactoring?

Test-driven development is used during feature development, bug fixes, refactoring, and behavior-heavy changes. It enforces failing-first tests and minimal production code, ensuring early defect detection whenever software behavior is modified.

What is the best way to write unit tests before coding?

The best way to write unit tests before coding is following the red-green-refactor cycle: write a failing test for a small feature, implement minimal code to pass, then refactor. This enforces mandatory test execution before production code changes.

Does test-driven development align with behavior-driven development requirements?

Yes, test-driven development aligns with behavior-driven development by using tests as living documentation that matches software requirements. This behavior-driven approach ensures feature implementation directly enforces expected system behavior through failing-first tests.
