-----------------------------------------+------------------------
I added the test code in the
[https://docs.djangoproject.com/en/4.0/topics/testing/tools/#management-
commands following link], into my Django 4.0 project `tests.py`:
{{{
from io import StringIO
from django.core.management import call_command
from django.test import TestCase
class ClosepollTest(TestCase):
def test_command_output(self):
out = StringIO()
call_command('closepoll', stdout=out)
self.assertIn('Expected output', out.getvalue())
}}}
The code fails with the following exception:
{{{

Found 11 test(s).
