Loadrunner進(jìn)行http接口壓力測試

1、使用Loadrunner進(jìn)行http接口壓力測試業(yè)務(wù)描述：在業(yè)務(wù)系統(tǒng)里進(jìn)行查詢操作，查詢的結(jié)果是通過請求http接口，從系統(tǒng)中處理并將結(jié)果以json字符串返回。使用Loadrunner對此類接口進(jìn)行壓力測試并記錄相關(guān)的性能指標(biāo)數(shù)據(jù)：1 .安裝Loadrunner本次測試過程使用Loadrunner11.0版本。2 .部署環(huán)境1 .接口服務(wù)器一臺；2 .用于運(yùn)行Loadrunner的壓力測試機(jī)1臺或N臺，在條件允許下，盡可能提供高配置的CPU和內(nèi)存。3 .接口服務(wù)器和壓力測試機(jī)建議應(yīng)部署于同一個局域網(wǎng)內(nèi)，否則測試過程和結(jié)果將受到網(wǎng)絡(luò)帶寬因素的影響無法順利進(jìn)行。三.編寫測試腳本方法一.通過java

2、編寫測試類，以jar包的方式引入Loadrunner進(jìn)行測試。優(yōu)點(diǎn)：便于解析接口響應(yīng)結(jié)果，同時避免由于LR腳本編寫不規(guī)范或配置問題，導(dǎo)致測試過程引發(fā)的未知錯誤。條件：運(yùn)行l(wèi)oadrunner的機(jī)器需要安裝jdk1.6的版本。1.編寫java測試類：CTLPTest.java,如下代碼1 packagecom;23 importjava.io.InputStream;4 .HttpURLConnection;5 .URL;6 importjava.util.Random;78 publicclassCTLPTest9 10 publicstaticvoidmain(Stringargs)11 1
