How to use the aioimaplib.aioimaplib.Commands function in aioimaplib

def test_uid_with_illegal_command(self):
        imap_client = yield from self.login_user('user', 'pass', select=True)

        for command in {'COPY', 'FETCH', 'STORE'}.symmetric_difference(Commands.keys()):
            with self.assertRaises(aioimaplib.Abort) as expected:
                yield from imap_client.uid(command)

            self.assertEqual(expected.exception.args,
                             ('command UID only possible with COPY, FETCH or STORE (was %s)' % command,))
