如何将数据模拟为请求。响应键入python

Question

我想写一些测试用例来练习isinstance（obj）中的object_check，请求。响应)逻辑。在我创建模拟数据作为请求.post. 模拟数据的类型始终是模拟类。这样，我如何重写模拟数据以便模拟数据可以是请求。回应？所以我可以练习d = obj.json()？在

from unittest.mock import patch, Mock
import unittest
import requests
from requests.exceptions import HTTPError
import pytest
def object_check(obj):
    if isinstance(obj, bytes):
        d = ujson.decode(obj.decode())
    elif isinstance(obj, requests.Response):
        d = obj.json()
    else:
        raise ValueError('invalid type')
    return d

def service_post(params):
    """
    trivial function that does a GET request
    against google, checks the status of the
    result and returns the raw content
    """
    url = "https://www.iamdomain.com"
    params = {'number': 1234, 'user_id': 1, 'name': 'john'}
    resp = requests.post(url, data=params)
    return object_check(resp)

@patch.object(requests, 'post')
def test_service_post(mock_request_post):
    data = {'number': 0000, 'user_id': 0, 'name': 'john'}
    def res():
        r = Mock()
        r.status_code.return_value = 200
        r.json.return_value = data
        return r
    mock_request_post.return_value = res()
    assert data == service_post(data)

如果要模拟text或content@属性值，请在text周围使用PropertyMock

@patch.object(requests, 'post')
def test_service_post(mock_request_post):
    data = {'number': 0000, 'user_id': 0, 'name': 'john'}
    def res():
        r = requests.Response()
        r.status_code = 200
        type(r).text = mock.PropertyMock(return_value=my_text)  # property mock
        def json_func():
            return data
        r.json = json_func
        return r
    mock_request_post.return_value = res()
    assert data == service_post(data)
