The dict returned by your fixture will then be used as parameters when instantiating Celery.

celery.contrib.pytest.celery_session_app(request, celery_config, celery_parameters, celery_enable_logging, use_celery_app_trap)[source]

Session Fixture: Return app for session fixtures.

celery.contrib.pytest.celery_session_worker(request, celery_session_app, celery_includes, celery_worker_pool, celery_worker_parameters)[source]

Fixture: Start worker in a thread, stop it when the test returns.

celery.contrib.pytest.celery_worker_parameters()[source]

Redefine this fixture to change the init parameters of Celery workers.

This can be used e. g. to define queues the worker will consume tasks from.

The dict returned by your fixture will then be used as parameters when instantiating WorkController.
