在django-channels测试模块中有一种非常方便的发送消息并等待向后消息的方法：
from channels.testing import WebsocketCommunicator
communicator = WebsocketCommunicator(app, url)
connected, subprotocol = await communicator.connect()
await communicator.send_json_to(data=my_data)
resp = await communicator.receive_json_from(timeout=my_timeout)
是否可以用相同的样式编写真实消费者的代码？我的意思是这样的：
class MyConsumer(AsyncJsonWebsocketConsumer):
async def some_method():
await self.send_json(some_json)
response = await self.receive_json(timeout=some_timeout)
# do something with response
