Unit Testing Games - TDD/Godot/GUT – Butch Wesley – GodotCon 2025

TDD and game creation don't always go hand in hand, but when they do it can make iterating on your game faster with less bugs. Regardless of your experience with TDD, programming or game development there will be something in this talk for you. We'll cover the basics of TDD, discuss the obvious aspects of a game to write tests for, and more involved examples of integration testing.

Examples will all be using Godot/GDScript/GUT (since I'm the author of the latter and that's what it works with), but most of the talk will apply to any testing framework, language or engine.
