test_database() does not use the database given - python-2.7

Question

I'm trying to test my models using peewee's test_database which is supposed to use the database passed when executing the SQL in the context block. However running the test, I noticed that the production database is always used, which should not be the case.
Here's the exception I get:
======================================================================
ERROR: test_Admin (__main__.DatabaseTestSuite)

Here's the test code:
from db import *
import unittest
from playhouse.test_utils import test_database
test_db = MySQLDatabase('testdb',
user='testuser',
password='testpass')
class DatabaseTestSuite(unittest.TestCase):
def test_Admin(self):
with test_database(test_db, (Admin), create_tables=True):
Admin.create(username="testuser",
email="testuser#email.com")
result = Admin.select().where(Admin.user == "testuser")
unittest.assertIsNotNone(result)
if __name__ == '__main__':
unittest.main()
I've opened an issue on the github page, but received no help so far. You can find the issue here. It should provide extra details if needed. Any help would be appreciated, thanks.

Answer 1

The model tuple has a single item and thus requires a trailing comma. Changing this
with test_database(test_db, (Admin), create_tables=True):
to this
with test_database(test_db, (Admin,), create_tables=True):
resolved it.
