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. Async loading races, missing assets at runtime, memory leaks from unreleased handles, and bundle fragmentation issues are all addressables bugs that only manifest after you've shipped. This
Unity
Running Unity tests locally is fine. Running them automatically on every pull request is how you actually catch regressions before they ship. Setting up Unity CI/CD is notoriously painful because of licensing, but GameCI makes it manageable. This guide covers a production-ready Unity testing pipeline using GitHub Actions
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. It destroys hours of player progress and triggers the most negative reviews your game will ever receive. This guide covers testing
Game Testing
Game AI bugs are among the most entertaining to watch and the most embarrassing to ship. NPCs that walk into walls, enemies that attack through solid geometry, companions that stand idle during combat — these are all AI bugs that escaped testing. Testing game AI is hard because AI behavior is
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. Platform-specific bugs, input differences, certification requirements, and performance constraints mean a test that passes on PC can fail catastrophically on mobile. This guide
Phaser.js
Phaser.js powers thousands of browser games, but testing it is notoriously tricky. The framework depends on browser APIs — WebGL, Canvas, Web Audio, requestAnimationFrame — that don't exist in Node.js. Most teams give up and test manually. This guide shows you a practical approach using Jest with jsdom,
Unreal Engine
Unreal Engine's Automation Testing system is powerful and chronically underdocumented. Most teams know IMPLEMENT_SIMPLE_AUTOMATION_TEST for smoke tests, but UE5's Spec framework — modeled after RSpec/Jasmine — enables the kind of structured, readable test suites that scale to complex game systems without becoming unmaintainable. This
Unity
Unity's Test Framework goes far beyond simple [Test] attributes on edit-mode assertions. Once your game reaches production complexity — async systems, multi-scene architectures, physics-driven gameplay — you need play mode tests that run inside the engine loop, performance benchmarks that catch frame-rate regressions, and a CI
Netcode
Multiplayer game bugs are among the hardest to reproduce — they live in the intersection of network timing, client prediction, and server authority. Testing netcode rigorously requires understanding the three core problems: lag compensation (server rewinds time to validate hit registration), rollback (clients re-simulate when authoritative state arrives), and determinism
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. AR anchors depend on real-world surfaces that don't exist in test environments. Framerate drops in VR cause motion sickness, making performance regression a
