Loadrunner开发测试脚本

Loadrunner开发测试脚本

 

         开发测试脚本能够经过录制，也能够手动开发，建议能录制的尽可能录制，省时省力，不能录制的只能费力本身开发了，具体看项目状况来决定。

         使用Loadrunner开发脚本过程当中和Jmeter同样，须要了解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作关联处理，在Action中插入->新建步骤中添加须要的函数，设置请求参数来逐步完成每一个请求。

 

         在开发流程测试脚本过程当中，每每须要将上一个请求的返回值做为下个请求的参数，这时候须要用到关联，不少时候Loadrunner自动关联不是万能的，须要咱们本身定义关联提取出须要的信息，如下为关联部分脚本：

Action() {          lr_start_transaction("打开登录页");            web_url("web_url",                    "URL={URL}/user/login.html",                    "TargetFrame=",                    "Resource=0",                    "Referer=",                    LAST);            lr_end_transaction("打开登录页", LR_AUTO);            lr_start_transaction("提交登录表单");            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("提交登录表单", 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);       //如下为提取“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，如抓包响应信息以下：

 

         提取orderId参数的关联脚本为：

web_reg_save_param("orderId",                    "LB=orderId\\\":\\\"",                    "RB=\\\"",                    LAST);

         脚本调试过程当中，根据脚本调试的目的来选取回放日志的类型，若是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：

 

 

         若是要查看关联提取值是否正确，选择扩展日志的参数替换；
