Python3 Unittest:如何使用操作符与MagicMocks进行比较

你应该重写 return_value __lt__ 的属性 MagicMock 对象,并使用 patch 使 f1 和 f2 返回定制的 MagicMock公司 实例:

from unittest.mock import patch, MagicMock
def f1():
    pass
def f2():
    pass
compareable_MagicMock_Instance = MagicMock()
compareable_MagicMock_Instance.__lt__.return_value = True
with patch('__main__.f1', return_value=compareable_MagicMock_Instance), patch('__main__.f2', return_value=compareable_MagicMock_Instance):
    type1_instance1 = f1()
    type1_instance2 = f2()
    compareResult = type1_instance1 < type1_instance2
    if compareResult:
        print('type1_instance1 is less than type1_instance2')

type1_instance1 is less than type1_instance2
