GD.Print Output Not Visible in Tests

GD.Print output may appear to be missing during tests.

Why This Happens

GD.Print writes to stdout through Godot's native OS::print(). dotnet test hides test-host stdout by default. The stream is global, so output also mixes with engine and fixture logs rather than belonging to a specific test.

Making GD.Print Visible

Enable detailed console logging:

dotnet test --logger "console;verbosity=detailed"

Your messages will appear mixed into the test-host stream.

Recommendation: Use ITestOutputHelper

For test logging, prefer xUnit's ITestOutputHelper over GD.Print:

[Collection<HeadlessCollection>]
public class MyTests(HeadlessFixture godot, ITestOutputHelper output)
{
    [Fact]
    public void MyTest()
    {
        var node = godot.Tree.Root;

        // Instead of: GD.Print(node.GetPath());
        output.WriteLine(node.GetPath());
    }
}

ITestOutputHelper associates output with the test, includes it in failure results, and works with IDE test explorers without mixing in engine logs. Keep GD.Print for runtime debugging rather than test logging.
