小编Mic*_*Liu的帖子

我的代码如下：

import pytest
import requests
from unittest import mock

@mock.patch('requests.get')
def test_verify(mock_request):
    mock_resp = mock.Mock()
    mock_resp.status_code = 404

    mock_request.return_value = mock_resp
    r = requests.get()

    with pytest.raises(requests.exceptions.HTTPError) as err_msg:
        r.raise_for_status()
    print(err_msg)

由于响应的状态代码设置为 404，我预计会引发 HTTPError。但是，有一个错误说明

Failed: DID NOT RAISE <class 'requests.exceptions.HTTPError'>

输出如下：

模拟请求 =

@mock.patch('requests.get')
def test_verify(mock_request):
    mock_resp = mock.Mock()
    mock_resp.status_code = 404

    mock_request.return_value = mock_resp
