Question

我有一个关于使用Python 3.8模拟修补异步对象的新手问题。我只想模拟post（）以便测试错误处理逻辑，但到目前为止我还没有运气。你能告诉我我做错了什么吗？非常感谢。

main.py

import httpx


test_data = {"id": "123"}

class DebugClass:
    def post(self):
        try:
            async with httpx.AsyncClient() as client:
                res = await client.post(url='http://localhost:8080', data=test_data)
            return "OK"
        except Exception as e:
            return "NOK"

test_main.py

from unittest import mock
from unittest.mock import patch, AsyncMock


from main import DebugClass

class TestClass:
    @mock.patch('httpx.AsyncClient.post', new_callable=AsyncMock)
    def test_post(self, mock_client_post):
        mock_client_post = AsyncMock(side_effect=TimeoutError)
        debug_class = DebugClass()
        res = debug_class.post()
        assert res == "NOK"

要安装：pytest。

以下是基于您的代码的示例：

pip install pytest-asyncio asynctest
