SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Tackle the pain of unclear requirements and brittle code by guiding you through test-driven development, ensuring behavior is captured by tests before implementation.

Core Features & Use Cases

  • Red-Green-Refactor Loop: Write a failing test, implement just enough to pass, and refactor with confidence.
  • Integration-Test Focus: Emphasize tests that validate public interfaces and real usage rather than internal details.
  • Safe, Incremental Delivery: Supports vertical slices and quick feedback cycles to reduce regression risk.

Quick Start

Write a failing spec for a new feature, then implement the minimal code to pass while keeping tests green.

FAQPage Schema
How do I practice test-driven development to build reliable software features?

Test-driven development builds reliable features by guiding you through red-green-refactor cycles, where you write a failing spec, implement minimal code to pass, and refactor with confidence. This captures behavior before implementation.

What is the red-green-refactor loop and how does it reduce regression risk?

The red-green-refactor loop is a test-first discipline where you write a failing test, implement just enough code to pass it, and then refactor. It reduces regression risk by validating public interfaces incrementally.

How do I write integration tests that validate public interfaces instead of internal details?

Integration testing focused on public interfaces validates real usage by specifying external behavior rather than internal implementation. You write meaningful specs for public contracts before writing the code that fulfills them.

Do I need prior TDD experience to apply test-first development to bug fixes?

Applying test-first development to bug fixes requires familiarity with TDD concepts, integration testing, and disciplined incremental design. You need to understand how to write meaningful specs before fixing code.

What's the best way to deliver software features incrementally without breaking existing tests?

Deliver features incrementally using vertical slices within red-green-refactor cycles. Write a failing spec for a new feature, implement the minimal code to pass, and keep tests green throughout the process for safe delivery.

When should I not use test-driven development for my software project?

Test-driven development is less suitable when public interfaces cannot be validated by tests or when refactoring is not routine. It requires clear requirements and environments where writing meaningful specs before code is feasible.
