SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Test-driven development (TDD) helps teams avoid unclear requirements and brittle code by requiring tests before implementation, guiding design and preventing regressions.

Core Features & Use Cases

  • Enforces a test-first workflow for new features, bug fixes, and refactors.
  • Provides rapid feedback by failing tests first, driving minimal, correct implementations.
  • Supports safe refactoring with a comprehensive test suite across projects.

Quick Start

Write a failing test for the intended behavior, implement the smallest amount of code to pass, and then refactor for clarity.

FAQPage Schema
What is test-driven development and how does it help avoid brittle code?▼

Test-driven development is an approach enforcing a test-first workflow that requires writing failing tests before implementation, helping teams avoid unclear requirements and brittle code while preventing regressions.

How do I apply the red-green-refactor cycle for feature development?▼

Apply the red-green-refactor cycle by writing a failing test for intended behavior, implementing minimal code to pass the test, then refactoring for clean design and safe regression prevention.

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

Yes, test-driven development enforces a test-first workflow suitable for bug fixes and refactors across projects, providing rapid feedback and supporting safe refactoring with a comprehensive test suite.

Why write failing unit tests first instead of writing tests after implementation?▼

Writing failing unit tests first provides rapid feedback that drives minimal, correct implementations, ensuring clear requirements and preventing regressions before code is written.

What's the best way to start unit tests for reliable software engineering?▼

The best way to start unit tests for reliable software is to write a failing test for the intended behavior, implement the smallest amount of code to pass, and then refactor for clarity.
