How to use the redislite.configuration.settings function in redislite

def test_configuration_settings(self):
        import redislite.configuration
        result = redislite.configuration.settings()
        del result['save']  # Save is a list which doesn't work with set
        result_set = set(result.items())
        expected_subset = set(
            {
                'dbdir': './',
                'daemonize': 'yes',
                'unixsocketperm': '700',
                'timeout': '0',
                'dbfilename': 'redis.db'
            }.items()
        )
        self.assertTrue(
            expected_subset.issubset(result_set)
        )
