以下教程为https://testdriven.io/ https://testdriven.io/,我创建了一个 websocket 测试来测试我的 websocket 连接:
# tests/test_websockets.py
from django.contrib.auth import get_user_model
from django.contrib.auth.models import Group
from django.test import Client
from channels.db import database_sync_to_async
from channels.layers import get_channel_layer
from channels.testing import WebsocketCommunicator
from nose.tools import assert_equal, assert_is_none, assert_is_not_none, assert_true
import pytest
from dc_wb.routing import application
from posts.models import Trip
TEST_CHANNEL_LAYERS = {
'default': {
'BACKEND': 'channels.layers.InMemoryChannelLayer',
},
}
@database_sync_to_async
def create_user(*,username='[email protected] /cdn-cgi/l/email-protection',password='pAssw0rd!',group='rider'):
# Create user.
user = get_user_model().objects.create_user(
username=username,
password=password
)
# Create user group.
user_group, _ = Group.objects.get_or_create(name=group)
user.groups.add(user_group)
user.save()
return user
@pytest.mark.asyncio
@pytest.mark.django_db(transaction=True)
class TestWebsockets:
async def test_authorized_user_can_connect(self, settings):
# Use in-memory channel layers for testing.
settings.CHANNEL_LAYERS = TEST_CHANNEL_LAYERS
print(settings.CHANNEL_LAYERS)
# Force authentication to get session ID.
client = Client()
user = await create_user()
client.force_login(user=user)
# Pass session ID in headers to authenticate.
communicator = WebsocketCommunicator(
application=application,
path='/taxi/',
headers=[(
b'cookie',
f'sessionid={client.cookies["sessionid"].value}'.encode('ascii')
)]
)
connected, _ = await communicator.connect()
assert_true(connected)
await communicator.disconnect()
我创造了pytest.ini
:
[pytest]
DJANGO_SETTINGS_MODULE = dc_wb.settings
python_files = test_websockets.py
但每当我跑步时pytest
,我刚刚收到此错误:

我对测试等都是完全陌生的;我什至不确定它是如何工作的,我尝试过一些研究,但不理解这些概念,也没有什么特别的东西可以解决这个问题。
