SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill guides teams to adopt a test-driven development workflow, ensuring tests drive design and prevent regressions.

Core Features & Use Cases

Enforces writing tests before implementation to capture expected behavior
Provides living documentation through test suites that describe product behavior
Supports fail-fast feedback loops and incremental refactoring across unit and integration tests

Quick Start

Start by writing a failing test for the target behavior, then implement the minimal code to make it pass.

FAQPage Schema

What is test-driven development and how does it improve software quality?▼

Test-driven development is a workflow where you write failing tests before implementation to capture expected behavior. It improves software quality by using tests to drive design, provide living documentation, and prevent regressions through fail-fast feedback loops.

How do I start writing unit tests before implementation?▼

To start writing unit tests first, write a failing test for the target behavior, then implement the minimal code required to make that test pass. This test-first design approach ensures incremental refactoring and clear behavioral verification.

Does test-driven development work for integration testing and iterative projects?▼

Test-driven development works for integration testing and iterative projects by supporting incremental refactoring across test suites. It provides fail-fast feedback loops and living documentation that describe product behavior throughout the development workflow.

What are the red flags and modification guidelines when using a test-first workflow?▼

Red flags in a test-first workflow indicate deviations from expected test-first design practices. The workflow includes clear modification guidelines and checks to ensure tests drive design, maintain behavioral verification, and prevent regressions during incremental refactoring.

Best way to use behavioral testing for living documentation in development?▼

The best way to use behavioral testing for living documentation is to enforce writing tests before implementation. These test suites describe product behavior clearly, providing fail-fast feedback and ensuring expected behavior is captured throughout iterative development.
