根因分析

使用了自定义标记（例如 @pytest.mark.slow）但未注册，因此 pytest 发出警告，并且 -m 'slow' 过滤可能无法按预期工作。

English

A custom marker (e.g., @pytest.mark.slow) is used but not registered, so pytest emits a warning and -m 'slow' filtering may not behave as expected.

解决方案

  1. 98% 成功率 
    # pytest.ini
[pytest]
markers =
    slow: marks tests as slow
    integration: requires external services
  2. 95% 成功率 
    # pyproject.toml
[tool.pytest.ini_options]
markers = [
  "slow: marks tests as slow",
  "integration: requires external services",
]

无效尝试

常见但无效的做法:

  1. 80% 失败

    Silences the warning but -m filtering still doesn't recognize the mark.

  2. 70% 失败

    -k matches names, not markers; results differ.

  3. 30% 失败

    Works but duplicates config; pytest.ini is simpler and canonical.
