性能測試分享---java協議（1）------jemter篇

這周嘗試了一把性能測試，之前都是測試網站的性能測試，java接口的性能測試還是頭一次，學到了很多，特此分享一下。

主要用到了兩個性能測試工具，一個是jmeter，一個是LoadRunner。

使用jmeter的測試方法：

1、下載jemeter的linux版本的，下載的文件裏包含了兩個jar包，一個是ApacheJMeter_core.jar,ApacheJMter_java.jar。分別把這兩個jar放到eclipse的Java Build Path的libraries下面。

2、創建編寫腳本的類，使他繼承AbstractJavaSamplerClient。初步結構是

private SampleResult results;

public void setupTest(JavaSamplerContext arg0) {
 results = new SampleResult();
 }

public Arguments getDefaultParameters() {
 Arguments params = new Arguments();
 return params;
 }

//測試執行的循環體，根據線程數和循環次數的不同可執行多次，類似於LoadRunner中的Action方法
 public SampleResult runTest(JavaSamplerContext arg0) {

results.sampleStart();

results.sampleEnd();
 results.setSuccessful(true);
 return results;
 }

//結束方法，實際運行時每個線程僅執行一次，在測試方法運行結束後執行，類似於LoadRunner中的end方法
 public void teardownTest(JavaSamplerContext arg0) {
 }

將需要循環的業務流程放到runTest方法裏。編寫好的代碼如下：

package app;

import http.HttpClient4;
 import http.HttpParameter;
 import http.HttpResp;
 import http.JsonUtil;

import java.io.IOException;
 import java.text.ParseException;

public class TheardTest extends AbstractJavaSamplerClient{
 private SampleResult results;
 public void setupTest(JavaSamplerContext arg0) {
 results = new SampleResult();
 }
 public Arguments getDefaultParameters() {
 Arguments params = new Arguments();
 return params;
 }
 public static String ramdonNum(int num){
 Random rd = new Random();

StringBuilder sb = new StringBuilder("");
 if (num <1){
 return null;
 }
 else{
 for(int i=1;i<=num;i++){
 int sr=rd.nextInt(9);
 sb.append(String.valueOf(sr));

}
 return sb.toString();

}}

public static void testCreditPay() throws ParseException{

 data = AES.encryptToBase64(data, encryptkey);
 try {
 method.setParameter("merchantaccount", merchantAccount);
 method.setParameter("data", data);
 method.setParameter("encryptkey", RSA_Encrypt.encrypt(encryptkey, PUBLIC_KEY));
 client.executeMethod(method);

 }

}

3、將寫好的class類和該類引入到的類都打成jar包，放到jemter文件的lib/ext文件下。將用到的其他的jar包放到lib文件夾下面。

4、啓動jemter後，創建先添加線程組，在添加sampler的java請求，如果之前步驟成功，在類名稱下拉列表裏會出現測試代碼打好jar包的類。之後操作jemter進行測試就OK啦。

下面在分享LoadRunner進行性能測試及環境優化。
