Load scene/prefab when running a test through the test runner

I am trying to write tests for my motor controller to make sure it works. However I want to load test stages that are either stored in prefabs or in a scene.

I am totally lost on how to load the scene that has all the prefabs OR somehow load the prefabs

I have found this way to do it: Unity - Scripting API: Resources.Load . I have seen some guys using it.
But I don’t know if it is the recommended way for loading assets for tests.
