Hello, I'm setting up an auctions application using channels and websockets. When I'm running the server the code works just fine, troubles arise when I'm trying to test my app.
asgiref==2.1.3 daphne==2.0.2 Django==2.0.2 channels==2.0.1 channels-redis==2.0.2 pytest==3.4.0 pytest-asyncio==0.8.0 a bunch of other stuff, but I think that's it for relevant libraries. Here is my consumer: class AuctionConsumer(WebsocketConsumer): @property @lru_cache(maxsize=None) def group_name(self): auction_id = self.scope['url_route']['kwargs']['auction_id'] return 'auction_{}'.format(auction_id) def connect(self): AsyncToSync(self.channel_layer.group_add)(self.group_name, self.channel_name) self.accept() Here is my routing: application = ProtocolTypeRouter({ 'websocket': URLRouter([ path("auctions/<auction_id>/", AuctionConsumer), ]), }) And here is my test: @pytest.mark.asyncio async def test_auction_consumer(mocker): communicator = WebsocketCommunicator(AuctionConsumer, 'auctions/1/') connected, subprotocol = await communicator.connect() assert connected # Test sending text await communicator.send_to(text_data='1') response = await communicator.receive_from() assert response == '1' # Close await communicator.disconnect() I'm running into the following problem; @property @lru_cache(maxsize=None) def group_name(self): > auction_id = self.scope['url_route']['kwargs']['auction_id'] E KeyError: 'url_route' I tried mocking at the top of my test: group_name = mocker.patch('auctions.consumers.AuctionConsumer.group_name') group_name.return_value = 'auction' But then I run into: def valid_group_name(self, name): if self.match_type_and_length(name): if bool(self.group_name_regex.match(name)): return True raise TypeError( "Group name must be a valid unicode string containing only ASCII " + > "alphanumerics, hyphens, or periods." ) E TypeError: Group name must be a valid unicode string containing only ASCII alphanumerics, hyphens, or periods. I also tried: scope = mocker.patch('auctions.consumers.AuctionConsumer.scope') scope.return_value = {'url_route': {}} But that got me: if not self.create and original is DEFAULT: raise AttributeError( > "%s does not have the attribute %r" % (target, name) ) E AttributeError: <class 'auctions.consumers.AuctionConsumer'> does not have the attribute 'scope' At this point I'm out of ideas. Anything I should try? Thanks in advance. -- You received this message because you are subscribed to the Google Groups "Django users" group.
