LoadRunner测试J2ME的Socket程序

LoadRunner有Windows Sockets协议用于支持Socket程序的测试脚本开发，但是有时候会录制不了或录制不全Socket脚本，而且Socket脚本的修改和参数化等方面都比较困难。

 

以J2ME Wireless Toolkit 2.0附带的NetworkDemo程序中的Socket Demo为例，用LoadRunner录制下来的脚本如下所示：

#include "lrs.h"

 

 

Action()

{

    lrs_create_socket("socket0", "TCP", "LocalHost=0", "Backlog=50",  LrsLastArg);

 

    lrs_create_socket("socket1", "TCP", "LocalHost=2663", "Backlog=50",  LrsLastArg);

 

    lrs_create_socket("socket2", "TCP", "RemoteHost=192.168.1.100:57328",  LrsLastArg);

 

    lrs_send("socket2", "buf0", LrsLastArg);

 

    lrs_receive("socket2", "buf1", LrsLastArg);

 

    lrs_close_socket("socket2");

 

    lr_think_time(13);

 

    lrs_create_socket("socket3", "TCP", "LocalHost=0", "Backlog=50",  LrsLastArg);

 

    lrs_create_socket("socket4", "TCP", "LocalHost=2669", "Backlog=50",  LrsLastArg);

 

    lrs_create_socket("socket5", "TCP", "LocalHost=0", "Backlog=50",  LrsLastArg);

 

    lrs_create_socket("socket6", "TCP", "LocalHost=2670", "Backlog=50",  LrsLastArg);

 

    lrs_create_socket("socket7", "TCP", "RemoteHost=192.168.1.100:57328",  LrsLastArg);

 

    lrs_send("socket7", "buf2", LrsLastArg);

 

    lrs_receive("socket7", "buf3", LrsLastArg);

 

    lrs_close_socket("socket7");

 

    lrs_create_socket("socket8", "TCP", "RemoteHost=192.168.1.100:57328",  LrsLastArg);

 

    lrs_send("socket8", "buf4", LrsLastArg);

 

    lrs_receive("socket8", "buf5", LrsLastArg);

 

    lrs_send("socket8", "buf6", LrsLastArg);

 

    lrs_receive("socket8", "buf7", LrsLastArg);

 

    lrs_send("socket8", "buf8", LrsLastArg);

 

    lrs_create_socket("socket9", "TCP", "LocalHost=0", "Backlog=50",  LrsLastArg);

 

    lrs_create_socket("socket10", "TCP", "LocalHost=2675", "Backlog=50",  LrsLastArg);

 

       /*

        * 发送消息

        */

 

    return 0;

}

 

发送和接收的Socket包数据可以在data.ws文件中找到，Socket Demo的客户端发送消息的操作并没有录制下来。

 

转变一下思路，可以采用Java Vuser来开发Java的Socket脚本，直接连接Socket Demo的服务器端并发送消息：
