Pytest Plugin List
==================
Below is an automated compilation of ``pytest``` plugins available on `PyPI <https://pypi.org>`_.
It includes PyPI projects whose names begin with "pytest-" and a handful of manually selected projects.
Packages classified as inactive are excluded.
For detailed insights into how this list is generated,
please refer to `the update script <https://github.com/pytest-dev/pytest/blob/main/scripts/update-plugin-list.py>`_.
.. warning::
Please be aware that this list is not a curated collection of projects
and does not undergo a systematic review process.
It serves purely as an informational resource to aid in the discovery of ``pytest`` plugins.
Do not presume any endorsement from the ``pytest`` project or its developers,
and always conduct your own quality assessment before incorporating any of these plugins into your own projects.
.. The following conditional uses a different format for this list when
creating a PDF, because otherwise the table gets far too wide for the
page.
