How do I Hybrid with UTF?

I can test pure ECS with UTF no problem. A minimal example would be to test that a GameObject with Monobehaviour that adds two IComponentData structs does that. Later tests could test the systems etc. run properly. So if I had this monobehaviour.

Code (CSharp):

1. public class TxAutotrophBehaviour : MonoBehaviour, IConvertGameObjectToEntity {
2.        
3.         void IConvertGameObjectToEntity.Convert(Entity entity, EntityManager dstManager, GameObjectConversionSystem conversionSystem)
4.         {
5.             if (enabled) {
6.                 dstManager.AddComponentData(entity, new  TxAutotroph());
7.                 dstManager.AddComponentData(entity, new  EnergyStore());
8.             }
9.  
10.         }
11.     }

How could I make something that runs in Test Runner and checks that I now have an entity with those ComponentData structs on it and check their Values? Ideally, I would like to do this both in straight code and separately with a test scene. Are there any examples out there that do something similar?
