I'm giving up on this. I spent a bunch of time trying to get it to work and couldn't.

My final attempt was inspired by https://github.com/encode/uvicorn/blob/e821fd1ff5653f989d500d41fa6ba070858f6843/tests/test_main.py#L10-L32

Here's the code that didn't work: ``` def test_asgi_app(app_client): from uvicorn.config import Config from uvicorn.main import Server

class CustomServer(Server):
    def install_signal_handlers(self):
        pass

def run_server():
    asyncio.set_event_loop(asyncio.new_event_loop())
    print("ooh new loop")
    config = Config(app=app_client.asgi_app, limit_max_requests=1, port=8642)
    config.load()
    server = CustomServer(config=config)
    server.run()

with concurrent.futures.ThreadPoolExecutor(max_workers=1) as executor:
    future = executor.submit(run_server)
    future.result()
    while not server.started:
        print(server.__dict__)
        time.sleep(0.01)
    assert 200 == urllib.request.urlopen("http://localhost:8642/").status
    # This line will raise if there's an exception:
    future.result()

`` I gotRuntimeError: There is no current event loop in thread 'ThreadPoolExecutor-1_0'`
