As I've been learning the Rust programming language and the Godot game engine (streaming at http://www.twitch.tv/paytonrules) I've been increasing the amount of testing I've been doing. I started by doing..well none.. and have been moving more and more into a TDD flow as I become more comfortable with the language and environment. One of the real challenges with TDD in Rust was figuring out how to use mock objects or substitutes.

Recently I started streaming my adventures with godot-rust over at https://www.twitch.tv/paytonrules. Come visit, while I'm still small enough to let you backseat code. The first completed project is a Blackjack game, where the code is entirely written in Rust using the Godot game engine. I wrote the code bottom-ish up, where I test-drove a command-line version of the app first, and then attached a mostly test-free Godot UI on top.
