Loadrunner 中随机选取关联对象

Posted 2020-10-27 CherrySu

我们在Loadrunner的测试过程中时常需要随机选择一个对象，进行下一步的操作，比如一个Table中有100行，测试的时候不能每次都选择同一行进行测试，而是要随机选择不同行，这样才能更好的模拟用户的真实情况

第一步，找出返回Table对象的请求，进行关联，关联的时候使用Ordinal=all找出所有的行

/*Correlation comment - Do not change!  Original value=‘aQoEp51‘ Name =‘all_the_Listcell‘ Type =‘Manual‘*/
    web_reg_save_param_ex(
        "ParamName=all_the_Listcell", 
        "LB/IC=zul.sel.Listcell\‘,\‘",
        "RB/IC=\‘,{$onClick:true,sclass:\‘yw-listview-cell\‘},{},",
        "Ordinal=all",
        SEARCH_FILTERS,
        "Scope=Body",
        LAST);

    web_submit_data("zkau_59",
        "Action=https://pet.sonystyle.com.cn/backoffice/zkau",
        "Method=POST",
        "RecContentType=text/plain",
        "Referer=https://pet.sonystyle.com.cn/backoffice/",
        "Snapshot=t256.inf",
        "Mode=html",
        ITEMDATA,
        "Name=dtid", "Value={clientInfo}", ENDITEM,
        "Name=cmd_0", "Value=echo", ENDITEM,
        "Name=opt_0", "Value=i", ENDITEM,
        "Name=uuid_0", "Value={mainWin}", ENDITEM,
        "Name=data_0", "Value={\"\":[\"{data_9}\"]}", ENDITEM,
        LAST);

第二步，判断关联是否成功，若成功则从关联对象all_the_Listcell中随机选取一个值，存储在one_of_the_Listcell中

arrSize=lr_paramarr_len("all_the_Listcell");
    if(arrSize>0){
        lr_save_string(lr_paramarr_random("all_the_Listcell"),"one_of_the_Listcell");
    }else{
        lr_error_message("Search_Condition4_OrderStatus have no response! OrderStatus=%s",lr_eval_string("{OrderStatus}"));
        lr_end_transaction("BackOffice_TC02_05_Search_Condition4_OrderStatus",LR_FAIL);
        return 0;
    }

第三步，调用

web_submit_data("zkau_32", 
        "Action=https://pet.sonystyle.com.cn/backoffice/zkau", 
        "Method=POST", 
        "RecContentType=text/plain", 
        "Referer=https://pet.sonystyle.com.cn/backoffice/", 
        "Snapshot=t91.inf", 
        "Mode=HTML", 
        ITEMDATA, 
        "Name=dtid", "Value={clientInfo}", ENDITEM, 
        "Name=cmd_0", "Value=onClick", ENDITEM, 
        "Name=uuid_0", "Value={one_of_the_Listcell}", ENDITEM, 
        "Name=data_0", "Value={\"pageX\":412,\"pageY\":439,\"which\":1,\"x\":107,\"y\":29}", ENDITEM, 
        LAST);
