【转】java接口的性能测试

这周尝试了一把性能测试，之前都是测试网站的性能测试，java接口的性能测试还是头一次，学到了很多，特此分享一下。

　　主要用到了两个性能测试工具，一个是jmeter，一个是LoadRunner。

　　使用jmeter的测试方法：

　　1、下载jemeter的linux版本的，下载的文件里包含了两个jar包，一个是ApacheJMeter_core.jar,ApacheJMter_java.jar。分别把这两个jar放到eclipse的Java Build Path的libraries下面。

　　2、创建编写脚本的类，使他继承AbstractJavaSamplerClient。初步结构是

private SampleResult results;

public void setupTest(JavaSamplerContext arg0) {

results = new SampleResult();

}

public Arguments getDefaultParameters() {

Arguments params = new Arguments();

return params;

}

//测试执行的循环体，根据线程数和循环次数的不同可执行多次，类似于LoadRunner中的Action方法

public SampleResult runTest(JavaSamplerContext arg0) {

results.sampleStart();

results.sampleEnd();

results.setSuccessful(true);

return results;

}

//结束方法，实际运行时每个线程仅执行一次，在测试方法运行结束后执行，类似于LoadRunner中的end方法

public void teardownTest(JavaSamplerContext arg0) {

}

 

 

 

将需要循环的业务流程放到runTest方法里。编写好的代码如下：

package app;

import http.HttpClient4;

import http.HttpParameter;

import http.HttpResp;

import http.JsonUtil;

import java.io.IOException;

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{

String PUBLIC_KEY=TheardTest.testConsult();

System.out.println(orderId);

Integer transtime = (int)(System.currentTimeMillis()/1000);

Integer currency = 156;

String  amount = "50";

String productcatalog = "1";

String productName = "123";

String productDesc = "小丸子";

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);

System.out.println(method.getStatusLine());

String respStr = method.getResponseBodyAsString();

System.out.println(respStr);

String result = AES.decryptFromBase64(respStr, encryptkey);

System.out.println(result);

//                    自动退款

Map<String, Object> mapjson=JsonUtil.parse(result);

Object obj = mapjson.get("yborderid");

String yborderid=obj.toString();

System.out.println("流水号："+yborderid);

TheardTest.refundTeseCase(yborderid,merchantAccount,amount);

method.releaseConnection();

　　3、将写好的class类和该类引入到的类都打成jar包，放到jemter文件的lib/ext文件下。将用到的其他的jar包放到lib文件夹下面。

　　4、启动jemter后，创建先添加线程组，在添加sampler的java请求，如果之前步骤成功，在类名称下拉列表里会出现测试代码打好jar包的类。之后操作jemter进行测试就OK啦。

　　下面在分享LoadRunner进行性能测试及环境优化。
