根因分析

测试套件以 -W error 或 filterwarnings=error 运行，将应用或第三方代码的 DeprecationWarning 升级为测试失败。

English

The test suite runs with -W error or filterwarnings=error, promoting a DeprecationWarning from application or third-party code into a test failure.

解决方案

  1. 95% 成功率 
    from datetime import datetime, timezone
dt = datetime.now(timezone.utc)
  2. 88% 成功率 
    # pyproject.toml
[tool.pytest.ini_options]
filterwarnings = [
  "error",
  "ignore::DeprecationWarning:legacy_lib.*",
  "ignore:datetime.datetime.utcnow:DeprecationWarning",
]

无效尝试

常见但无效的做法:

  1. 85% 失败

    noqa is for linters; pytest's warning filter isn't affected by inline noqa comments.

  2. 70% 失败

    Doesn't fix the deprecated call; the warning still fires elsewhere in the codebase.
