LoadRunner測試J2ME的Socket程式

LoadRunner有Windows Sockets協議用於支援Socket程式的測試指令碼開發，但是有時候會錄製不了或錄製不全Socket指令碼，而且Socket指令碼的修改和引數化等方面都比較困難。

 

以J2ME Wireless Toolkit 2.0附帶的NetworkDemo程式中的Socket Demo為例，用LoadRunner錄製下來的指令碼如下所示：

#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);

 

       /*

        * 傳送訊息

        */

 

    return 0;

}

 

傳送和接收的Socket包資料可以在data.ws檔案中找到，Socket Demo的客戶端傳送訊息的操作並沒有錄製下來。

 

轉變一下思路，可以採用Java Vuser來開發Java的Socket指令碼，直接連線Socket Demo的伺服器端併傳送訊息：
