Test-First Copilot (Greenfield Edition)

Craft provably high quality software using GitHub Copilot

By Vivek Ganesan, Kiran Kashyap, Kamal Raj Sekar

AI-assisted code needs more testing discipline than hand-written code, because the assistant will produce plausible mistakes with confidence. This book builds a complex application from an empty repository with test-driven development and GitHub Copilot, using the test suite to keep the AI pair programmer honest at every step.

You will learn how to structure prompts, write specifications Copilot can build against safely, and use the red-green-refactor loop to catch AI-generated mistakes before they ship. The examples target .NET and React developers.
