Testing with Celery is divided into two parts:

* Unit & Integration: Using ``celery.contrib.pytest``.

* Smoke / Production: Using :pypi:`pytest-celery <pytest-celery>` >= 1.0.0

Installing the pytest-celery plugin will install the ``celery.contrib.pytest`` infrastructure as well,

alongside the pytest plugin infrastructure. The difference is how you use it.

.. warning::

Both APIs are NOT compatible with each other. The pytest-celery plugin is Docker based

and the ``celery.contrib.pytest`` is mock based.

To use the ``celery.contrib.pytest`` infrastructure, follow the instructions below.

The pytest-celery plugin has its `own documentation <https://pytest-celery.readthedocs.io/>`_.
