SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill guides developers to implement backend APIs by using test code and OpenAPI specs, reducing guesswork and aligning implementations with required behavior.

Core Features & Use Cases

TDD-driven API implementation: write code that passes tests derived from test suites and OpenAPI specs.
Framework-agnostic guidance: applies to Node.js, Python, Go, Java, and other stacks with consistent architecture (controllers/services/repositories/models).
OpenAPI-driven scaffolding: translates API contracts into concrete code structure and data models for maintainable code.

Quick Start

Start by running the test suite and implementing the minimal API code to satisfy the OpenAPI spec.

FAQPage Schema

How do I implement backend APIs from OpenAPI specs using TDD?▼

Backend API implementation from OpenAPI specs using TDD involves deriving endpoint code, data models, and validation logic directly from test suites to ensure behavior matches required contracts, reducing guesswork and aligning implementations with expected behavior.

Can I use this TDD API workflow with Python or Go frameworks?▼

Yes, this TDD API workflow applies to Python, Go, Java, and Node.js. It provides framework-agnostic guidance that maps OpenAPI contracts into a consistent project structure of controllers, services, repositories, and models across diverse tech stacks.

What is OpenAPI-driven scaffolding for backend development?▼

OpenAPI-driven scaffolding translates API contracts into concrete code structures and data models. It establishes a maintainable architecture by defining controllers, services, and repositories that directly satisfy the documented endpoints and validation rules.

How do I structure a backend project for test-driven API development?▼

Structuring a backend project for test-driven API development requires separating concerns into controllers, services, repositories, and models. This consistent architecture ensures reliable, maintainable code that can be systematically validated against test suites and OpenAPI specifications.

Does this approach require an existing OpenAPI specification to build APIs?▼

Yes, an OpenAPI specification is required to build APIs with this approach. The specification acts as the source of truth for scaffolding data models, endpoints, and validation rules, while the test suite validates the minimal implementation needed to satisfy the contract.
