Loadrunner開發測試腳本

Loadrunner開發測試腳本

 

         開發測試腳本能夠經過錄制，也能夠手動開發，建議能錄製的儘可能錄製，省時省力，不能錄製的只能費力本身開發了，具體看項目狀況來決定。

         使用Loadrunner開發腳本過程當中和Jmeter同樣，須要瞭解HTTP傳輸原理，使用Fiddler等工具進程抓包，根據請求信息編寫請求表單，根據響應信息判斷返回值作關聯處理，在Action中插入->新建步驟中添加須要的函數，設置請求參數來逐步完成每一個請求。

 

         在開發流程測試腳本過程當中，每每須要將上一個請求的返回值做爲下個請求的參數，這時候須要用到關聯，不少時候Loadrunner自動關聯不是萬能的，須要咱們本身定義關聯提取出須要的信息，如下爲關聯部分腳本：

Action() {          lr_start_transaction("打開登錄頁");            web_url("web_url",                    "URL={URL}/user/login.html",                    "TargetFrame=",                    "Resource=0",                    "Referer=",                    LAST);            lr_end_transaction("打開登錄頁", LR_AUTO);            lr_start_transaction("提交登錄表單");            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("提交登錄表單", 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」請求的「loanId」參數，在「出借」請求中調用；          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);       //如下爲提取「出借」請求的關聯，在「出借跳轉」請求參數中調用；          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("出借跳轉");          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("出借跳轉", LR_AUTO);            return 0; }

         提取數據根據請求響應信息的格式編寫關聯腳本，如抓包響應信息以下：

 

         提取orderId參數的關聯腳本爲：

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

         腳本調試過程當中，根據腳本調試的目的來選取回放日誌的類型，若是要查看提交表單請求的參數信息，選擇擴展日誌的高級跟蹤：

 

 

         若是要查看關聯提取值是否正確，選擇擴展日誌的參數替換；
