根因分析

skipIf 条件中的拼写错误：`version_info` 拼写错误或访问不正确，导致在测试发现期间出现 AttributeError。

English

A typo in the skipIf condition: `version_info` is misspelled or accessed incorrectly, causing an AttributeError during test discovery.

解决方案

  1. 95% 成功率 
    Correct the attribute name: `@unittest.skipIf(sys.version_info < (3, 7), 'requires Python 3.7+')`
  2. 90% 成功率 
    Use pytest markers instead: `@pytest.mark.skipif(sys.version_info < (3,7))`

无效尝试

常见但无效的做法:

  1. 80% 失败

    This defeats the purpose of conditional skipping and may cause failures in unsupported environments.

  2. 90% 失败

    Decorators cannot be wrapped in try-except in that way; it will still raise an error at import time.
