How to setup and teardown temporary django db for unit testing?
- by blokeley
I would like to have a python module containing some unit tests that I can pass to hg bisect --command.
The unit tests are testing some functionality of a django app, but I don't think I can use hg bisect --command manage.py test mytestapp because mytestapp would have to be enabled in settings.py, and the edits to settings.py would be clobbered when hg bisect updates the working directory.
Therefore, I would like to know if something like the following is the best way to go:
import functools, os, sys, unittest
sys.path.append(path_to_myproject)
os.environ['DJANGO_SETTINGS_MODULE'] = 'myapp.settings'
def with_test_db(func):
"""Decorator to setup and teardown test db."""
@functools.wraps
def wrapper(*args, **kwargs):
try:
# Set up temporary django db
func(*args, **kwargs)
finally:
# Tear down temporary django db
class TestCase(unittest.TestCase):
@with_test_db
def test(self):
# Do some tests using the temporary django db
self.fail('Mark this revision as bad.')
if '__main__' == __name__:
unittest.main()
I should be most grateful if you could advise either:
If there is a simpler way, perhaps subclassing django.test.TestCase but not editing settings.py or, if not;
What the lines above that say "Set up temporary django db" and "Tear down temporary django db" should be?
