示例1: testUdpClientRecv
# 需要導入模塊: from pymodbus.client.sync import ModbusUdpClient [as 別名]
# 或者: from pymodbus.client.sync.ModbusUdpClient import _recv [as 別名]
def testUdpClientRecv(self):
''' Test the udp client receive method'''
client = ModbusUdpClient()
self.assertRaises(ConnectionException, lambda: client._recv(1024))
client.socket = mockSocket()
self.assertEqual('', client._recv(0))
self.assertEqual('\x00'*4, client._recv(4))示例2: testBasicSyncUdpClient
# 需要導入模塊: from pymodbus.client.sync import ModbusUdpClient [as 別名]
# 或者: from pymodbus.client.sync.ModbusUdpClient import _recv [as 別名]
def testBasicSyncUdpClient(self):
''' Test the basic methods for the udp sync client'''
# receive/send
client = ModbusUdpClient()
client.socket = mockSocket()
self.assertEqual(0, client._send(None))
self.assertEqual(1, client._send('\x00'))
self.assertEqual('\x00', client._recv(1))
# connect/disconnect
self.assertTrue(client.connect())
client.close()
# already closed socket
