Root Cause

A custom marker such as @pytest.mark.slow is used without being registered in pytest.ini, pyproject.toml, or conftest.py, so pytest treats it as a typo.

generic

中文

使用了如 @pytest.mark.slow 的自定义标记，但未在 pytest.ini、pyproject.toml 或 conftest.py 中注册，pytest 将其视为拼写错误。

Workarounds

  1. 98% success 
    # pytest.ini
[pytest]
markers =
    slow: marks tests as slow
    integration: needs external services
  2. 98% success 
    # pyproject.toml
[tool.pytest.ini_options]
markers = [
  'slow: marks tests as slow',
]

Dead Ends

Common approaches that don't work:

  1. 70% fail

    Silences the warning but --strict-markers will still fail the run, and the marker remains unregistered.

  2. 80% fail

    Changes test semantics; skip is not the same as a user-defined tag used for selection.
