robotframework使用之一 udp测试

一，使用的lib如下：UdpLibrary.py 主要用于测试基于udp的16进制协议的测试。socket的read是阻塞式的，使用robot自带timeout来进行超时计算，重复测试的关键字

Repeat Keyword也是系统自带的，详见user guide

import os import sys import socket class SipgwLibrary: def init(self, port_str): print "port is ",port_str self.recv_str = '' port = int(port_str) self.s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) self.s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) host = '' self.s.bind((host, port)) def set_server(self, host, port): self.ser_address = (host, int(port)) def connect(self, host, port): self.host = host self.textport = port try: self.port = int(self.textport) except ValueError: self.port = socket.getservbyname(self.textport, 'udp') self.s.connect((self.host, self.port)) def send(self, data): print "send str[%s] to %s:%d"%(data, self.ser_address[0], self.ser_address[1]) self.s.sendto(data, self.ser_address) def read(self): # while 1: buf, address = self.s.recvfrom(2048) print "Got data[", buf, "] from", address self.recv_str = buf def recv_should_be(self, expected_recv): if expected_recv != self.recv_str: raise AssertionError("Expected recv to be '%s' but was '%s'" % (expected_recv, self.recv_str)) def run(self): self.init(30000) # self.connect("localhost", 20000) self.set_server('172.17.27.19', 20000) self.send("hello") self.read() print "after read" self.recv_should_be("OK") if __name__ == "main": sip_test = SipgwLibrary() print "test" sip_test.run()
