Django Testing Using AsyncClient and Authentication - django

Question

I have a basic Asynchronous Class Based View:
class AsyncAuthenticationView(View):
async def post(self, request, *args, **kwargs):
authenticated: bool = await sync_to_async(lambda: request.user.is_authenticated)()
if not authenticated:
return HttpResponse('Unauthorized', status=401)
return HttpResponse('Success', status=200)
And two simple tests:
#pytest.fixture
def authenticated_async_client(user) -> AsyncClient:
client = AsyncClient()
client.force_login(user)
return client
class TestAsyncAuthenticationView:
#pytest.mark.asyncio
async def test_with_async_client(self, authenticated_async_client: AsyncClient):
"""This test fails, with response code 401 instead of 200"""
response = await authenticated_async_client.post(
reverse('auth-test'),
'abc',
content_type="text/html",
)
assert 200 == response.status_code # fails with 401
#pytest.mark.asyncio
async def test_with_async_request_factory(self, async_rf: AsyncRequestFactory, user):
"""This test succeeds correctly with response code 200"""
r = async_rf.post('/fake-url', 'abc', content_type='text/html')
r.user = user
r.session = {}
response = await AsyncAuthenticationView().post(r)
assert 200 == response.status_code
The first test which uses the AsyncClient always fails to authenticate returning status code 401 while the second test is passing just fine with status code 200.
Based on the docs the AsyncClient has all the same methods, so I am not not why the test is failing. Perhaps there is a different authentication method that needs to be used?
The AsyncRequestFactory that is being used in the second test is from the pytest-django package.
Any help would be much appreciated. Thank you.
