Game Testing
Game UIs are notoriously undertested. Most teams apply automated testing to gameplay logic and leave menus, HUDs, settings screens, and inventory UIs to manual QA. This is understandable — game UI testing is genuinely harder than web UI testing — but it leaves a class of bugs that consistently escape to players:
Unity
Unity Addressables is one of those systems that works fine in the editor and breaks in surprising ways in production builds.
Unity
Running Unity tests locally is fine. Running them automatically on every pull request is how you actually catch regressions before they ship.
Game Testing
Game save systems are among the most critical — and most under-tested — parts of any game. A bug that corrupts save data doesn't just cause a crash.
Game Testing
Game AI bugs are among the most entertaining to watch and the most embarrassing to ship.
Game Testing
Releasing a game on PC, PlayStation, Xbox, iOS, and Android isn't five releases — it's five completely different QA challenges running in parallel.
Phaser.js
Phaser.js powers thousands of browser games, but testing it is notoriously tricky.
Unreal Engine
Unreal Engine's Automation Testing system is powerful and chronically underdocumented.
Unity
Unity's Test Framework goes far beyond simple [Test] attributes on edit-mode assertions.
Netcode
Multiplayer game bugs are among the hardest to reproduce — they live in the intersection of network timing, client prediction, and server authority.
Godot
GUT (Godot Unit Test) is the de-facto testing framework for Godot projects, and Godot 4 brought significant changes to GDScript that affect how you write and structure tests. If you've gone through the GUT getting-started tutorials and written basic assert_eq tests, this guide covers the
Unity
XR (Extended Reality) applications in Unity present unique testing challenges. You can't run a headset in CI. Controller input is hardware-dependent.
