根因分析

pytest 配置了 filterwarnings = error，将 DeprecationWarning 变为测试失败；代码或依赖仍调用 utcnow()。

English

pytest is configured with filterwarnings = error, turning DeprecationWarning into a test failure; the code or a dependency still calls utcnow().

解决方案

  1. 95% 成功率 
    from datetime import datetime, timezone
now = datetime.now(timezone.utc)
  2. 80% 成功率 
    # pytest.ini
# filterwarnings =
#   error
#   ignore:datetime.datetime.utcnow:DeprecationWarning:legacy_lib

无效尝试

常见但无效的做法:

  1. 60% 失败

    Hides all warnings and defeats the purpose; future breakages go unnoticed.

  2. 55% 失败

    Ignores all deprecations including ones from your own code; not targeted.
