Loadrunner开发测试脚本

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;
