There is some pretty and clean method to suspend logging in tests with unittest.mock.patch method.

foo.py:

import logging


logger = logging.getLogger(__name__)

def bar():
    logger.error('There is some error output here!')
    return True

tests.py:

from unittest import mock, TestCase
from foo import bar


class FooBarTestCase(TestCase):
    @mock.patch('foo.logger', mock.Mock())
    def test_bar(self):
        self.assertTrue(bar())

And python3 -m unittest tests will produce no logging output.
