Capture and make assertions on ``transaction.on_commit()`` `callbacks <https://docs.djangoproject.com/en/3.0/topics/db/transactions/#performing-actions-after-commit>`__.
This allows you to write your tests with the ``TestCase``, rather than needing the slower ``TransactionTestCase`` to actually commit the transactions.
This package was made as a first pass for `Django PR #12944 <https://github.com/django/django/pull/12944>`__, which is a solution for `Ticket #30457 “on_commit should be triggered in a TestCase” <https://code.djangoproject.com/ticket/30457>`__.
The PR has been merged to Django and has been released in version 3.2, so this package can now be considered a backport.
Read more in my blog post `The Fast Way to Test Django transaction.on_commit() Callbacks <https://adamj.eu/tech/2020/05/20/the-fast-way-to-test-django-transaction-on-commit-callbacks/>`__.
Installation
============
Use **pip**:
.. code-block:: bash
python -m pip install django-capture-on-commit-callbacks
Requirements
============
Python 3.7 to 3.10 supported.
Django 3.2 to 4.0 supported.
**Note:** This package is not needed on Django 4.0+ and it will error on usage for such versions.

API
===
``capture_on_commit_callbacks(*, using="default", execute=False)``
------------------------------------------------------------------
Acts as a context manager that captures ``on_commit`` callbacks for the given database connection.
It returns a list that contains, on exit of the context, the captured callback functions.
From this list you can make assertions on the callbacks or call them to invoke their side effects, emulating a commit.
All arguments must be passed as keyword arguments.
``using`` is the alias of the database connection to capture callbacks for.
``execute`` specifies whether to call all the callbacks automatically as the context manager exits, if no exception has been raised.
For example, you can test a commit hook that sends an email like so:
.. code-block:: python
from django.core import mail
from django.test import TestCase
from django_capture_on_commit_callbacks import capture_on_commit_callbacks
class ContactTests(TestCase):
def test_post(self):
with capture_on_commit_callbacks() as callbacks:
response = self.client.post(
"/contact/",
{"message": "I like your site"},
)
self.assertEqual(response.status_code, 200)
self.assertEqual(len(callbacks), 1)
# Execute the callback
callbacks[0]()
self.assertEqual(len(mail.outbox), 1)
self.assertEqual(mail.outbox[0].subject, "Contact Form")
self.assertEqual(mail.outbox[0].body, "I like your site")
The same test can be written a bit more succinctly with ``execute=True``:
.. code-block:: python
from django.core import mail
from django.test import TestCase
from django_capture_on_commit_callbacks import capture_on_commit_callbacks
class ContactTests(TestCase):
def test_post(self):
with capture_on_commit_callbacks(execute=True) as callbacks:
response = self.client.post(
"/contact/",
{"message": "I like your site"},
)
self.assertEqual(response.status_code, 200)
self.assertEqual(len(callbacks), 1)
self.assertEqual(len(mail.outbox), 1)
self.assertEqual(mail.outbox[0].subject, "Contact Form")
self.assertEqual(mail.outbox[0].body, "I like your site")
``TestCaseMixin``
-----------------
A mixin class to be added to your custom ``TestCase`` subclass.
It adds one method, ``captureOnCommitCallbacks()`` that aliases ``capture_on_commit_callbacks()``, to match the ``camelCase`` style of unittest assertions.
You can add to your custom ``TestCase`` classes like so:
.. code-block:: python
from django import test
from django_capture_on_commit_callbacks import TestCaseMixin
class TestCase(TestCaseMixin, test.TestCase):
pass
You could then rewrite the above tests with your custom ``TestCase`` class like so:
.. code-block:: python
from django.core import mail
from example.test import TestCase
class ContactTests(TestCase):
def test_post(self):
with self.captureOnCommitCallbacks(execute=True) as callbacks:
response = self.client.post(
"/contact/",
{"message": "I like your site"},
)
self.assertEqual(response.status_code, 200)
self.assertEqual(len(callbacks), 1)
self.assertEqual(len(mail.outbox), 1)
self.assertEqual(mail.outbox[0].subject, "Contact Form")
self.assertEqual(mail.outbox[0].body, "I like your site")
