性能测试分享—JMeter篇

简介:
+关注继续查看
 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;

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();
HttpClient client = new HttpClient();
PostMethod method = new PostMethod("http://xxxxxxxx/xxxxxx/api/bankcard/credit/pay");
String key=TheardTest.ramdonNum(6);

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);

  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。
