from __future__ import absolute_import
# Invenio runs tests as standalone modules, instead of from their package
# hierarchy. This means that this test module is executed as if you ran
# 'python celery_unit_tests.py'. This causes the directory of this file to be added
# to the sys.path. This causes the module invenio.celery to be importable
# as just 'celery' since modules/miscutil/lib is now in sys.path. Thus, the real
# celery package is no longer importable, causing an import error in
# invenio.celery. Solutions could be to rename invenio.celery, however then you
# cannot start celery workers with 'celeryd -A invenio' and must use something
# like 'celeryd -A invenio.<new name>.celery' instead.
#
# Below lines removes the directory of this file from the sys.path so modules
# are imported from their proper location.
