Shared database connections for multi-threaded Django test setups.
Project description
This proxy database backend is designed to speed up multi-threaded testing setups.
It enables those setups (for instance using LiveServerTestCase) to use Django’s standard TestCase - where each test runs in its own transaction - instead of the much slower TransactionTestCase that needs to flush the whole database between each tests.
It is NOT intended for production use, only for faster testing setups.
This project support Django versions 1.6, and Python 2.7, 3.2 and 3.3.
Setup
First, install django-shareddb:
$ pip install django-shareddb
Then, simply update your settings to use its wrapping engine:
DATABASES = {
'default': {
'ENGINE': 'shareddb.backends.shareddb',
'INNER_ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'test-dbsharing',
}
}
Since altering those settings is very frequent, django-shareddb also provides a simple patch_databases function:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'test-dbsharing',
}
}
if os.environ['FAST_TESTS']:
import shareddb
DATABASES = shareddb.patch_databases(DATABASES)
Once the settings are ready, simply replace your calls to Django’s LiveServerTestCase with the django-shareddb variant:
from shareddb import testcases
class MyTests(testcases.LiveServerTestCase):
def test_something(self):
# Your test here
The django-shareddb LiveServerTestCase is simply a clone of Django’s version, but uses django.test.TestCase instead of django.test.TransactionTestCase.

Testing
This libraries has been succesfully tested with sqlite and postgresql.
If you want to test it with other databases, please clone it and alter dev/settings.py for your setup, then run ./manage.py test.
