## What it is
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

## Facets
- artifact type: framework
- maturity: active
- function: testing, mocking, e2e-testing
- domain: testing, developer-tools
- platform: cross-platform, game-engine
