Godot Runtime Required for Test Method

Id	Category	Severity	Enabled
GdUnit0501	Attribute Usage	Error	True

Problem Description

Test methods that use Godot functionality (such as Node, Scene, or other Godot types) must be annotated with [RequireGodotRuntime]. This ensures proper test execution in the Godot engine environment.

Add [RequireGodotRuntime] to either test method or class level.

Error example:

    [TestCase] // ❌ GdUnit0501: Test method 'TestWithGodot' uses Godot functionality but is not annotated with '[RequireGodotRuntime]'.
    public void TestWithGodot() 
    {
        var instance = new Node2D()
        AssertThat(instance).IsNotNull();
    }

How to fix:

Add [RequireGodotRuntime] to method or class level when testing Godot functionality:

    [RequireGodotRuntime] // ✅ Correct: Method level annotation
    [TestCase]
    public void TestWithGodot() 
    {
        var instance = new Node2D();
        AssertThat(instance).IsNotNull();
    }

    // OR

    [RequireGodotRuntime] // ✅ Correct: Class level annotation
    public class MyTestClass
    {
        [TestCase]
        public void TestWithGodot() 
        {
            var instance = new Node2D();
            AssertThat(instance).IsNotNull();
        }
    }
