How to use the influxdb.resultset.ResultSet function in influxdb

def test_query(self):
        from influxdb.resultset import ResultSet
        databases = query('show databases')
        self.assertEqual(type(databases), ResultSet)
        databases = [database['name'] for database in list(databases.get_points())]
        self.assertIn(TEST_DATABASE, databases)

response = self.request(
            url="query",
            method=method,
            params=params,
            data=None,
            expected_response_code=expected_response_code
        )

        data = response._msgpack
        if not data:
            if chunked:
                return self._read_chunked_response(response)
            data = response.json()

        results = [
            ResultSet(result, raise_errors=raise_errors)
            for result
            in data.get('results', [])
        ]

        # TODO(aviau): Always return a list. (This would be a breaking change)
        if len(results) == 1:
            return results[0]

        return results

def _read_chunked_response(response, raise_errors=True):
        result_set = {}
        for line in response.iter_lines():
            if isinstance(line, bytes):
                line = line.decode('utf-8')
            data = json.loads(line)
            for result in data.get('results', []):
                for _key in result:
                    if isinstance(result[_key], list):
                        result_set.setdefault(
                            _key, []).extend(result[_key])
        return ResultSet(result_set, raise_errors=raise_errors)
