Set django-q logging level to ERROR for tests
hyperkitty/tests/settings_test.py:
When using django-q with the "sync": True
configuration option, while
setting its logging level to "WARNING"
the test suite generates large
output (several Mb!) with the following message:
Preserving django database connections because sync=True. Beware that
tasks are now injected in the calling context/transactions which may
result in unexpected bahaviour.
As this behavior makes CI pipelines fail (due to logs being to large)
and is heavy on downstreams packaging hyperkitty and running tests, the
logging level is set to "ERROR"
in this commit.
Fixes #330 (closed)
