How to use the pyzabbix.ZabbixResponse function in pyzabbix

def test_init(self):
        zr = ZabbixResponse()
        self.assertEqual(zr.failed, 0)
        self.assertEqual(zr.processed, 0)
        self.assertEqual(zr.time, 0)
        self.assertEqual(zr.total, 0)
        self.assertEqual(zr.chunk, 0)

def test_send(self, mock_socket):
        mock_data = b'\x01\\\x00\x00\x00\x00\x00\x00\x00'
        mock_socket.return_value = mock_socket
        mock_socket.recv.side_effect = (b'ZBXD', mock_data, self.resp_body)

        zm = ZabbixMetric('host1', 'key1', 100500, 1457358608)
        zs = ZabbixSender()
        result = zs.send([zm])
        self.assertIsInstance(result, ZabbixResponse)
        self.assertEqual(result.chunk, 1)
        self.assertEqual(result.total, 10)
        self.assertEqual(result.failed, 10)

def test_FunctionalSenderOld(self):
        cur_date_unix = int(now())
        m = [
            ZabbixMetric('host2', 'key3', 'IDDQD'),
            ZabbixMetric('host1', 'key1', 33.1, cur_date_unix)
        ]

        z = ZabbixSender('127.0.0.1', 10051).send(m)

        self.assertIsInstance(z, ZabbixResponse)
        self.assertEqual(z.total, 2)
        self.assertEqual(z.processed, 2)
        self.assertEqual(z.failed, 0)
        self.assertEqual(z.chunk, 1)

def test_repr(self):
        zr = ZabbixResponse()
        result = json.dumps({'processed': zr._processed,
                             'failed':    zr._failed,
                             'total':     zr._total,
                             'time':      str(zr._time),
                             'chunk':     zr._chunk})
        self.assertEqual(zr.__repr__(), result)
