Example Code

from fastapi import FastAPI, HTTPException
app = FastAPI()

@app.websocket("/process/dummy_ws")
async def websocket_dummy(websocket: WebSocket):
    await websocket.accept()
    data = await websocket.receive_text()
    while True:
        await websocket.send_text(data)
        await asyncio.sleep(0.1)

Description

I'm trying to test the example simple Webscoket using the following pytest test.

from app.main import app  
from fastapi.testclient import TestClient
import pytest

@pytest.fixture()
def client():
    yield TestClient(app)

def test_dummy_ws(client):
    with client.websocket_connect("/process/dummy_ws") as websocket:
        websocket.send_text("test")
        data = websocket.receive_text()
        assert data == "test"

The test hangs forever and never finishes. Is there something missing im not aware of?
