GdUnit

The GdUnit host is a .NET test executable that runs GDScript suites in a private copy of your game with embedded libgodot. It supports pure GDScript games and scenes containing C# components.

Create a host from the game directory:

dnx 2dog add --gdunit

Or select GdUnit in the interactive host picker. The generated host includes a sample GDScript test and its MTP runner configuration. See the GdUnit configuration guide for customization. Run from the project root:

dotnet test MyGame.gdunit

The root global.json that 2dog creates selects MTP for dotnet test. With a root global.json of your own that does not, run from MyGame.gdunit/.

Use GdUnit's official documentation to write tests. Testing with GdUnit explains the 2dog-specific execution and reporting differences.
