将 moto 从版本 1.3.14 更新到 1.3.15/1.3.16 会中断测试并引发异常。

即使单独使用注释也会引发错误。

我使用这个requiriments.txt文件：

moto==1.3.16

此测试示例适用于 moto 1.3.14，但不适用于较新版本：

from moto import mock_s3
import unittest

@mock_s3
class TestStringMethods(unittest.TestCase):

    def test_upper(self):
        self.assertEqual('foo'.upper(), 'FOO')


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

这是执行时的错误python3 -m unittest mytest.py：

(venv) ~/p/mocotest $ python3 -m unittest mytest.py

    if self.is_local and self.temp_original is not DEFAULT:
AttributeError: '_patch' object has no attribute 'is_local'

版本：

  • 蟒蛇 3.8.5
  • 点 20.0.2

有什么建议吗？

注意 1：为了测试，我使用的是一个干净的新venv环境，安装的唯一库是moto.

注意 2：使用 1.3.14 可以正常工作，但在安装依赖项时会出现警告：

ERROR: python-jose 3.2.0 has requirement ecdsa<0.15, but you'll have ecdsa 0.16.1 which is incompatible

  • moto这是和mock库之间的兼容性问题
  • 使用 moto 版本moto==1.3.16和 mock 版本mock==4.0.2为我解决了这个问题。

同样的问题。moto 模型的补丁功能会影响模拟功能。

（解决方法）：注释行受影响

def __exit__(self, *exc_info):
        """Undo the patch."""
        #if self.is_local and self.temp_original is not DEFAULT:
        #    setattr(self.target, self.attribute, self.temp_original)
        #else:
        #    delattr(self.target, self.attribute)
        #    if not self.create and (not hasattr(self.target, self.attribute) or
        #                self.attribute in ('__doc__', '__module__',
        #                                   '__defaults__', '__annotations__',
        #                                   '__kwdefaults__')):

        #del self.temp_original
        #del self.is_local
        #del self.target
        exit_stack = self._exit_stack
        #del self._exit_stack
        return exit_stack.__exit__(*exc_info)
