Testing
Indie developers ship games with 1-5 person teams, no dedicated QA engineers, and budgets that don't stretch to $40K/year test automation platforms. But shipping without a QA pipeline means bugs reach players — and players leave negative reviews. This guide shows how to build a QA pipeline that
Testing
Emulators are convenient but inadequate for mobile game testing. They don't throttle. They don't have real touch latency. They run on your development machine's GPU. A game that runs at 60 FPS in the emulator can drop to 20 FPS on a 3-year-old Android
Testing
Multiplayer game testing is one of the hardest domains in software QA. You're testing distributed systems with real-time constraints, player-visible latency, determinism requirements, and adversarial users. A bug that's impossible to reproduce on LAN destroys the experience at 200ms latency. This guide covers testing strategies specific
Testing
Performance is a feature in games. A 60 FPS game feels completely different from the same game at 30 FPS. Players notice stutters, long load times, and frame drops — and they stop playing. Performance testing catches regressions before players experience them. This guide covers tools and techniques for profiling game
Testing
Game testing is often manual — play through levels, look for bugs. But most game logic is testable code: inventory systems, physics interactions, AI decisions, save/load functionality. The Unity Test Framework brings standard unit and integration testing to game development. This guide covers how to write meaningful automated tests for
Game Development
Godot uses GUT (third-party, community-maintained), while Unity ships with its own Test Framework (built-in, supported by Unity Technologies). Both enable unit and integration testing of game code, but they differ in setup complexity, CI/CD integration, test isolation, and framework maturity. This comparison helps you understand the testing tradeoffs before
Game Development
Integration tests in Godot verify that multiple nodes, scenes, and autoloads work together correctly. Unlike unit tests that test a single script, integration tests instantiate real scenes, trigger real signals, and assert on the resulting state. GUT supports this with add_child_autoqfree(), scene instantiation helpers, and frame-await utilities. Key
Game Development
Godot 4 runs headlessly with --headless — no display required in CI. Combined with GUT's CLI runner, you can run your full test suite in GitHub Actions on every push. This guide covers setting up the CI pipeline, caching the Godot binary, running GUT tests, and reporting results. Key
Game Development
Beyond basic assertions, GUT provides mock objects, spy capabilities, and signal testing that let you isolate and verify complex game behavior. This guide covers GUT's advanced features: creating doubles (mocks/stubs), asserting method calls, testing signal emissions, and testing scene interactions in GDScript. Key Takeaways GUT doubles (mocks)
Game Development
GUT (Godot Unit Test) is the de facto unit testing framework for Godot games. It integrates directly into the Godot editor, lets you write tests in GDScript alongside your game code, and runs headlessly for CI pipelines. This guide covers installation, writing your first tests, and the assertion API. Key
Testing
Unity XR projects often go untested until a physical headset is involved, but that's unnecessary and slow. This guide covers Unity Test Framework, XR Simulation, controller input mocking, and Play Mode tests for XR rigs — everything you need to validate VR and AR behavior automatically.
