Pytest-django

-------------------

Improvements
^^^^^^^^^^^^

* Add support for :ref:`rollback emulation/serialized rollback
<test-case-serialized-rollback>`. The :func:`pytest.mark.django_db` marker
has a new ``serialized_rollback`` option, and a
:fixture:`django_db_serialized_rollback` fixture is added.

* Official Python 3.10 support.

* Official Django 4.0 support (tested against 4.0rc1 at the time of release).

* Drop official Django 3.0 support. Django 2.2 is still supported, and 3.0
will likely keep working until 2.2 is dropped, but it's not tested.

* Added pyproject.toml file.

* Skip Django's `setUpTestData` mechanism in pytest-django tests. It is not
used for those, and interferes with some planned features. Note that this
does not affect ``setUpTestData`` in unittest tests (test classes which
inherit from Django's `TestCase`).

Bugfixes
^^^^^^^^

* Fix :fixture:`live_server` when using an in-memory SQLite database.

* Fix typing of ``assertTemplateUsed`` and ``assertTemplateNotUsed``.

-------------------

Improvements
^^^^^^^^^^^^

* Add a fixture :fixture:`django_capture_on_commit_callbacks` to capture
:func:`transaction.on_commit() <django.db.transaction.on_commit>` callbacks
in tests.

-------------------

Improvements
^^^^^^^^^^^^

* Add experimental :ref:`multiple databases <multi-db>` (multi db) support.

* Add type annotations. If you previously excluded ``pytest_django`` from
your type-checker, you can remove the exclusion.

* Documentation improvements.

-------------------

Improvements
^^^^^^^^^^^^

* Official Django 3.2 support.

* Documentation improvements.

Bugfixes
^^^^^^^^

* Disable atomic durability check on non-transactional tests (910).

-------------------

Improvements
^^^^^^^^^^^^

* Add the :fixture:`async_client` and :fixture:`async_rf` fixtures (864).

* Add :ref:`django_debug_mode <usage>` to configure how ``DEBUG`` is set in tests (228).

* Documentation improvements.

Bugfixes
^^^^^^^^

* Make :fixture:`admin_user` work for custom user models without an ``email`` field.

-------------------

Compatibility
^^^^^^^^^^^^^

This release contains no breaking changes, except dropping compatibility
with some older/unsupported versions.

* Drop support for Python versions before 3.5 (868).

Previously 2.7 and 3.4 were supported. Running ``pip install pytest-django``
on Python 2.7 or 3.4 would continue to install the compatible 3.x series.

* Drop support for Django versions before 2.2 (868).

Previously Django>=1.8 was supported.

* Drop support for pytest versions before 5.4 (868).

Previously pytest>=3.6 was supported.

Improvements
^^^^^^^^^^^^

* Officially support Python 3.9.

* Add ``pytest_django.__version__`` (880).

* Minor documentation improvements (882).

Bugfixes
^^^^^^^^

* Make the ``admin_user`` and ``admin_client`` fixtures compatible with custom
user models which don't have a ``username`` field (457).

* Change the ``admin_user`` fixture to use ``get_by_natural_key()`` to get the
user instead of directly using ``USERNAME_FIELD``, in case it is overridden,
and to match Django (879).

Misc
^^^^

* Fix pytest-django's own tests failing due to some deprecation warnings
(875).
