What you expected to happen vs. what actually happened

I want to testing the websocket url about testing url in django, you should use reverse() let django url to match the name to route, but django didn,t support not View class url

Here is my routing.py

import logging

from channels.testing import ChannelsLiveServerTestCase, WebsocketCommunicator

from api.consumers.notifyConsumer import NotifyConsumer

logger = logging.getLogger(__name__)

websocket_urlpatterns = [
    path('ws/notify/<str:username>/', NotifyConsumer.as_asgi(), name='notify-consumer'),
    path('ws/chat/<str:username>/', ChatConsumer.as_asgi(), name='chat-consumer'),
]

My Testing test_routing.py

from django.test import TestCase, Client
from django.urls import reverse

class WebSocketRoutingTestCase(TestCase):
    def test_notify_consumer_routing(self):
        client = Client()
        url = reverse('notify-consumer', kwargs={'username': 'testuser'})
        response = client.get(url)
        self.assertEqual(response.status_code, 200)
        self.assertEqual(response.content, b'WebSocket Handshake')

    def test_chat_consumer_routing(self):
        client = Client()
        url = reverse('chat-consumer', kwargs={'username': 'testuser'})
        response = client.get(url)

        self.assertEqual(response.status_code, 200)
        self.assertEqual(response.content, b'WebSocket Handshake')

How you're running Channels (runserver? daphne/runworker? Nginx/Apache in front?)
