python3中的`MagicMock`能和int相比吗？

Question

我正在迁移我的项目的python版本(2->3)。测试适用于python2，但抱怨适用于python3，错误如下

TypeError: '>' not supported between instances of 'MagicMock' and 'int'

下面是一个最小的例子

# test_mock.py
try:
    from mock import MagicMock
except:
    from unittest.mock import MagicMock

def test_mock_func():
    a = MagicMock()
    b = a.value

    if b > 100:
        assert True
    else:
        assert True 

只需运行py.test .

这些黑客技术不起作用

MagicMock.__le__ = some_le_method # just not working

MagicMock.__le__.__func__.__code = some_le_method.__func__.__code__ # wrapper_descriptor does not have attribute __func__

Answer 1

您应该在b或a.value内部分配__gt__

# self is MagicMock itself
b.__gt__ = lambda self, compare: True
# or
a.value.__gt__ = lambda self, compare: True
