  warnings.warn(PytestConfigWarning(...))

- **Domain:** python
- **Category:** config_error
- **Verification:** ai_generated
- **Fix Rate:** 80%

## Root Cause

An option in pytest.ini/pyproject.toml is not recognized by the installed pytest version, often because it was renamed or moved to a plugin.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| 7.x | active | — | — |
| 8.x | active | — | — |

## Workarounds

1. **** (90% success)
   ```
   Check the current option name with `pytest --help | grep junit` and update pyproject.toml accordingly (e.g. `junit_suite_name` → `junit_suite_name` is valid in 7.x+; for older, use `--junit-suite-name`).
   ```
2. **** (85% success)
   ```
   Move plugin-specific options to their plugin's config section, or install the plugin that provides the option.
   ```

## Dead Ends

- **** — Removes other valid options and breaks test discovery. (60% fail)
- **** — Blocks upgrades and security fixes without addressing the option. (55% fail)
