GdUnit4 is an embedded unit testing framework for the Godot 4 game engine, supporting tests written in both GDScript and C#. It integrates directly into the Godot editor with a test inspector, test discovery, extensive fluent assertions, mocking, argument matchers, fuzzing, and scene testing.

Use cases

• write unit tests for gdscript code in godot 4
• test c# scripts in a godot project
• run test-driven development in godot
• mock dependencies in godot game tests
• test godot scenes and node behavior
• fuzz test functions with random inputs
• run godot tests from the editor or CI

When to choose

• you develop games or tools with Godot 4.x and need automated testing
• you want tests embedded in the Godot editor with an inspector UI
• you need both GDScript and C# test support
• you want TDD workflows, mocking, and scene testing in one framework

When to avoid

• you use Godot 3.x or a non-Godot engine
• you need standalone testing outside the Godot editor/runtime
• your project requires a testing framework for non-game applications
