Loadrunner开发测试脚本

 

         开发测试脚本可以通过录制,也可以手动开发,建议能录制的尽量录制,省时省力,不能录制的只能费力自己开发了,具体看项目情况来决定。

         使用Loadrunner开发脚本过程中和Jmeter一样,需要了解HTTP传输原理,使用Fiddler等工具进程抓包,根据请求信息编写请求表单,根据响应信息判断返回值做关联处理,在Action中插入->新建步骤中添加需要的函数,设置请求参数来逐步完成每个请求。

 

         在开发流程测试脚本过程中,往往需要将上一个请求的返回值作为下个请求的参数,这时候需要用到关联,很多时候Loadrunner自动关联不是万能的,需要我们自己定义关联提取出需要的信息,以下为关联部分脚本:

Action()

{

         lr_start_transaction("打开登陆页");

 

         web_url("web_url",

                   "URL={URL}/user/login.html",

                   "TargetFrame=",

                   "Resource=0",

                   "Referer=",

                   LAST);

 

         lr_end_transaction("打开登陆页", LR_AUTO);

 

         lr_start_transaction("提交登陆表单");

 

         web_submit_data("web_submit_data",

                   "Action={URL}/user/login.do",

                   "Method=POST",

                   "TargetFrame=",

                   "Referer=",

                   ITEMDATA,

                   "Name=acct", "Value={username}", ENDITEM,

                   "Name=beforeURL", "Value=", ENDITEM,

                   "Name=password", "Value={password}", ENDITEM,

                   "Name=verifyCode", "Value=1234", ENDITEM,

                   LAST);

 

         lr_end_transaction("提交登陆表单", LR_AUTO);

 

         lr_start_transaction("出借列表");

 

         web_url("web_url",

                   "URL={URL}/front/investmentList.html",

                   "TargetFrame=",

                   "Resource=0",

                   "Referer=",

                   LAST);

 

         lr_end_transaction("出借列表", LR_AUTO);

   

    //提取“去出借”请求的“loanId”参数,在“出借”请求中调用;

         web_reg_save_param("loanId",

                   "LB=type=\"hidden\" id=\"loanId\" value=\"",

                   "RB=\"/>",

                   LAST);

 

         lr_start_transaction("去出借");

 

         web_url("web_url",

                   "URL={URL}/loanObject/2220003.html",

                   "TargetFrame=",

                   "Resource=0",

                   "Referer=",

                   LAST);

 

         lr_end_transaction("去出借", LR_AUTO);

 

    //以下为提取“出借”请求的关联,在“出借跳转”请求参数中调用;

         web_reg_save_param("functionNum",

                   "LB=functionNum\\\":\\\"",

                   "RB=\\\",\\\"orderId",

                   LAST);

 

         web_reg_save_param("orderId",

                   "LB=orderId\\\":\\\"",

                   "RB=\\\"",

                   LAST);

 

         web_reg_save_param("ordDate",

                   "LB=ordDate\\\":\\\"",

                   "RB=\\\"",

                   LAST);

 

         web_reg_save_param("investorId",

                   "LB=investorId\\\":\\\"",

                   "RB=\\\"",

                   LAST);

 

         web_reg_save_param("borrowerId",

                   "LB=investorId\\\":\\\"",

                   "RB=\\\"",

                   LAST);

 

         web_reg_save_param("fullAmount",

                   "LB=fullAmount\\\":",

                   "RB=,\\",

                   LAST);

 

         web_reg_save_param("amount",

                   "LB=amount\\\":",

                   "RB=,\\",

                   LAST);

 

         web_reg_save_param("signStr",

                   "LB=signStr\\\":\\\"",

                   "RB=\\\"",

                   LAST);

 

         web_reg_save_param("freezeOrdId",

                   "LB=freezeOrdId\\\":\\\"",

                   "RB=\\\"",

                   LAST);

 

         lr_start_transaction("出借");

 

         web_submit_data("web_submit_data",

                   "Action={URL}/loanObject/invest.do",

                   "Method=POST",

                   "RecContentType=application/json",

                   "TargetFrame=",

                   "Referer=",

                   ITEMDATA,

                   "Name=loanId", "Value={loanId}", ENDITEM,

                   "Name=amount", "Value=100", ENDITEM,

                   LAST);

 

         lr_end_transaction("出借", LR_AUTO);

 

 

         lr_start_transaction("出借跳转");

         web_submit_data("web_submit_data",

                   "Action={URL}/intf/bid.do",

                   "Method=POST",

                   "EncodeAtSign=YES",

                   "TargetFrame=",

                   "Referer=",

                   "Mode=HTML",

                   ITEMDATA,

                   "Name=jsonDataString", "Value={\"functionNum\":\"{functionNum}\",\"orderId\":\"{orderId}\",\"ordDate\":\"{ordDate}\",\"investorId\":\"{investorId}\",\"borrowerId\":\"{borrowerId}\",\"loanId\":\"{loanId}\",\"amount\":{amount},\"fullAmount\":{fullAmount},\"fee\":0.00,\"feeRate\":1.00,\"terminal\":\"pc\",\"maxTenderRate\":0.5,\"isFreeze\":\"Y\",\"freezeOrdId\":\"{freezeOrdId}\",\"signStr\":\"{signStr}\"}", ENDITEM,

                   LAST);

 

         lr_end_transaction("出借跳转", LR_AUTO);

 

         return 0;

}

         提取数据根据请求响应信息的格式编写关联脚本,如抓包响应信息如下:

 

         提取orderId参数的关联脚本为:

         web_reg_save_param("orderId",

                   "LB=orderId\\\":\\\"",

                   "RB=\\\"",

                   LAST);

         脚本调试过程中,根据脚本调试的目的来选取回放日志的类型,如果要查看提交表单请求的参数信息,选择扩展日志的高级跟踪:

 

 

         如果要查看关联提取值是否正确,选择扩展日志的参数替换;
