Root Cause

A custom marker is used in tests but not registered in pytest configuration, causing a warning during collection.

generic

中文

测试中使用了自定义标记，但未在 pytest 配置中注册，导致收集期间出现警告。

Workarounds

  1. 95% success 
    Register the marker in pytest.ini: `[pytest]
markers =
    slow: marks tests as slow`
  2. 90% success 
    Use `pytest --markers` to list all registered markers and ensure the custom one is defined.

Dead Ends

Common approaches that don't work:

  1. 80% fail

    This removes useful metadata for test selection and organization.

  2. 60% fail

    The warning may escalate to an error in future pytest versions, and it hides potential typos.
