模块安装M

Question

我试图用以下代码片段模拟类：

import unittest
from mock import Mock

class TestMocking(unittest.TestCase):
   def test_mock_method_returns(self):
       my_mock = Mock()
       my_mock.my_method.return_value = "hello"
       self.assertEquals("hello",my_mock.my_method())


if __name__ == "__main__":
     unittest.main()

运行代码时，出现以下错误：

^{pr2}$

我用以下命令安装了mock： pip安装模拟

我有以下输出：

Answer 1

您使用的是python3.5；mock在该版本中已经是part of the standard library，您不需要安装它。您应该这样导入它：

from unittest.mock import Mock
