升级到最新 moto 版本（1.3.15 和 1.3.16）后测试中断

Question

将 moto 从版本 1.3.14 更新到 1.3.15/1.3.16 会破坏测试并引发异常。

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，但不适用于较新的版本：

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

版本：

• Python 3.8.5
• 点 20.0.2

有什么建议吗？

注 1：为了进行测试，我使用了一个全新的venv环境，并且安装的唯一库是moto.

注2：使用1.3.14工作正常，但在安装依赖项时出现警告：

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

Answer 1

• moto这是和mock库之间的兼容性问题
• 使用摩托版本moto==1.3.16和模拟版本mock==4.0.2为我解决了这个问题。
