You can use call_args or call_args_list as well.
A quick example would look like:
import mock
import unittest
class TestExample(unittest.TestCase):
@mock.patch('lib.event.Event')
def test_example1(self, event_mocked):
args, kwargs = event_mocked.call_args
args = event_mocked.call_args.args # alternatively
self.assertEqual(args, ['metadata_example', 'action_example'])
I just quickly written this example for somebody who might need it – I have not actually tested this so there might be minor bugs.
