Creating a game object for Test Runner

I have spent a lot of time looking and experimenting and so far it seems like the answer is that it can't be done but maybe someone knows something I do not.

I have a couple of Monobehavoir child classes that have utility methods, like save to persistent file, get internal state, etc. I would like to be able to set up unit tests for some of these in Test Runner. But I am not finding any way to create a GameObject without a scene. My editor menu test would create on in the currently active scene but they still did to allow me to make calls to the object or really get a solid reference to it.

Is it just a basic fact that Monobehavor children cannot be tested with unit tests with TesrRunner?

 

You can definitely test MonoBehaviours with Unity's Test runner. Here's an example:

The tutorial is using Resources.Load with a prefab but you can just as easily do something like this:

Code (CSharp):

1. var testObj = new GameObject();
2. var myComponent = testObj.AddComponent(typeof(ComponentTypeToTest)) as ComponentTypeToTest;
3.  
4. // test stuff

Does this answer your question or am I misunderstanding?
