如何使用原生Django的测试框架而不是pytest来测试Django频道？

import unittest
from channels.testing import WebsocketCommunicator
from myapp.consumers import MyConsumer

class MyConsumerTestCase(unittest.TestCase):
    def setUp(self):
        # 设置测试环境
        self.communicator = WebsocketCommunicator(MyConsumer.as_asgi(), "/ws/")

    def tearDown(self):
        # 清理测试环境
        self.communicator = None

    def test_channel_connection(self):
        # 测试频道连接
        connected, _ = await self.communicator.connect()
        self.assertTrue(connected)

    def test_channel_receive(self):
        # 测试频道接收消息
        await self.communicator.send_json_to({"type": "websocket.receive", "text": "Hello"})
        response = await self.communicator.receive_json_from()
        self.assertEqual(response["text"], "Hello")

    def test_channel_disconnect(self):
        # 测试频道断开连接
        await self.communicator.connect()
        await self.communicator.disconnect()
        self.assertFalse(self.communicator.connected)

python manage.py test myapp.tests.MyConsumerTestCase
