I try to make a reusable app which uses transaction.atomic().
When I run my test.py (below) for my reusable app, I get the below errors.
Is it possible to test this reusable app outside of a Django project?
[[[
import unittest
from transaction_utils.transaction import retry
class TestRetry(unittest.TestCase):
@retry
def my_func(self):
return 123
def test_passthrough(self):
self.assertEqual(self.my_func(), 123)
if __name__ == '__main__':
unittest.main()
]]]
