根因分析

项目配置了 filterwarnings = error，将警告转为失败。第三方库或被测代码发出未在忽略列表中的 DeprecationWarning。

English

The project configures filterwarnings = error, turning warnings into failures. A third-party library or the code under test emits a DeprecationWarning that is not in the ignore list.

解决方案

  1. 90% 成功率 
    [tool.pytest.ini_options]
filterwarnings = [

  "ignore:datetime.datetime.utcnow:DeprecationWarning",
  "ignore:.*is deprecated:DeprecationWarning:thirdparty.module",
]

    # before:
from datetime import datetime
datetime.utcnow()

# after:
from datetime import datetime, timezone
datetime.now(timezone.utc)

无效尝试

常见但无效的做法:

  1. 40% 失败

    Reintroduces noisy warnings and hides genuine deprecations you wanted to catch.

  2. 70% 失败

    Not applied in CI where the config is used; local passes but CI fails.
