Demultiplexer testing with enforcing order

Channels 1.1.1

I’m tryign to do a test with a Demultiplexer, and it complains about enforcing ordering. I have the flag set, but do I have to add an order value to every message I send?

class ROSChannelTestCase(ChannelTestCase):
    """
    ROS Channel Test Case
    Test if we can do things
    """

    def test_ros_channel(self):
        client = HttpClient()
        # user = User.objects.create_user(username='test', email='[e-mail]', password='123456')
        # client.login(username='test', password='123456')
        with apply_routes([Demultiplexer.as_route(path='/new/')]):
            client.send_and_consume(u'websocket.connect', path='/new/')
            self.assertIsNone(client.receive())

@andrewgodwin maybe HttpClient has bad naming, but it designed to test WebSocket consumers. I can make PR to rename it… @cjds if you test consumers with enforce_ordering you need to add order at message manually:

client.send_and_consume(u'websocket.connect', {'order': 0}, path='/new/')
client.send_and_consume(u'websocket.receive', {'order': 1}, path='/new/')

A lot of the testing examples seem wrong, if this is not the way it works. I’ll see if I can edit it and improve it.
