性能测试分享---java协议（1）------jemter篇

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; import java.text.ParseException; import java.text.SimpleDateFormat; import java.util.Calendar; import java.util.Date; import java.util.Map; import java.util.Random;import org.apache.commons.httpclient.HttpClient; import org.apache.commons.httpclient.HttpException; import org.apache.commons.httpclient.methods.PostMethod;

} 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();

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(); } catch (HttpException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace();

return aes; }catch (HttpException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } client.shutdown(); return "出错啦";}public static void refundTeseCase(String yborderid,String merchantAccount,String amount) throws IOException{String url ="http://xxxxxxxx/xxxxxxx"; HttpClient4 client =HttpClient4.createDefault(); HttpParameter parameter = new HttpParameter(); parameter.add("merchantaccount", merchantAccount); parameter.add("merchantrefundid", "093032323"); parameter.add("transorderid", yborderid); parameter.add("amount", amount);HttpResp rep; try { rep = client.doPost(url, parameter,"utf-8"); System.out.println(rep.getStatusCode()); System.out.println(rep.getText("utf-8")); }catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } }//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(); try { testCreditPay(); } catch (ParseException e) { // TODO Auto-generated catch block e.printStackTrace(); } 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) { }}

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。
