# Our test suite should cover:
# - all supported databases against current Python and Django
# - at least one test run for each older supported version of Python and Django
# - at least one test run for each supported Elasticsearch version
# - a test run against Django's git main and active stable branch (allowing failures)
# - test runs with USE_EMAIL_USER_MODEL=yes and DISABLE_TIMEZONE=yes

# Current configuration:
# - django 3.2, python 3.8, postgres, parallel
# - django 3.2, python 3.8, mysql
# - django 4.1, python 3.9, sqlite
# - django 4.2, python 3.10, mysql, parallel
# - django 4.1, python 3.10, postgres, parallel, USE_EMAIL_USER_MODEL=yes
# - django 4.2, python 3.11, postgres, parallel, DISABLE_TIMEZONE=yes
# - django stable/4.2.x, python 3.10, postgres (allow failures)
# - django main, python 3.10, postgres, parallel (allow failures)
# - elasticsearch 5, django 3.2, python 3.8, sqlite
# - elasticsearch 6, django 3.2, python 3.8, postgres
# - elasticsearch 7, django 4.1, python 3.8, postgres
# - elasticsearch 8, django 4.2, python 3.10, sqlite, USE_EMAIL_USER_MODEL=yes

# Some tests are run in parallel by passing --parallel to runtests.py.
# When running tests in parallel, some errors cannot be pickled and result in
# non-helpful tracebacks (see https://code.djangoproject.com/ticket/29023).
# Thus, we keep one test run without --parallel for each supported database.
# ElasticSearch tests are not run in parallel as the test suite is not thread-safe.
