根因分析

CI 使用 `-W error`（或配置中的 `filterwarnings = error`）运行 pytest，因此测试执行期间抛出的任何 DeprecationWarning 都会变成失败。这通常在 Python 小版本升级后出现。

English

CI runs pytest with `-W error` (or `filterwarnings = error` in config), so any DeprecationWarning raised during test execution becomes a failure. This often appears after a Python minor upgrade.

解决方案

  1. 90% 成功率 
    Ignore specific known-safe warnings via pytest config:

# pyproject.toml
[tool.pytest.ini_options]
filterwarnings = [
  "error",
  "ignore:datetime.datetime.utcnow\(\) is deprecated:DeprecationWarning",
]
  2. 98% 成功率 
    Fix the deprecated call site:

from datetime import datetime, timezone
datetime.now(timezone.utc)  # replaces utcnow()

无效尝试

常见但无效的做法:

  1. 60% 失败

    Hides all warnings, including ones the team intentionally turned into errors to catch regressions.

  2. 70% 失败

    Only suppresses in that scope; other tests using the same deprecated API still fail.
