Hello. I have a question for fastapi testing with pytest and if someone could help me it would be very much appreciated!

Essentially, what I need to do within my test is to simulate a server restart. But I do not understand how the server is actually started in pytest.

We are running our API with hypercorn. Hypercorns serv() function in our main.py takes the app as a parameter and from my understanding runs the server like you normally would with "hypercorn main:app" by just running the main.py. I just don't understand how the server is actually started with pytest. All we do in pytest (same as in this video) is to define the TestClient, but from my understanding the TestClient is only the one ACCESSING the server that is already running. Therfore I don't know how I could simulate a restart of the server in pytest (like stopping and restarting the execution of "hypercorn main:app" in cmd).
Could anyone help me out here and tell me what I am misunderstanding?
