Go Feature Development

Overview

Layer-by-layer TDD workflow for Go/Fiber backends following clean architecture. Build inside-out: domain → application → infrastructure → interfaces.

Core principle: Every layer gets its own test before implementation. Never skip a layer.

When to Use

• Adding a new API endpoint to a Go/Fiber service
• Implementing a new use case or business logic
• Adding CRUD operations with PostgreSQL
• Building domain entities with validation
