1、先完成jmeter脚本编写,具体怎么写此处不再详述,可以参考其他文档、
2、有时你会发现jmeter脚本执行后,有些响应信息你需要提取到文件中,以便后续使用;
怎么实现呢?个人思路就是,先写个java类,这个类的功能就是参数保存到指定文件;
然后进行java请求,保存该文件
具体步骤:
2.1 idea打开创建一个java项目,添加依赖的jmeter jar包
2.2 创建 OutputService 和PerformenceTest两个类
1 import java.io.File; 2 import java.io.PrintWriter; 3 4 /** 5 * Created by Administrator on 2017/8/28. 6 */ 7 public class OutputService { 8 public static void output(String filename,String csName,String csPwd,String ghsName,String ghsPwd,String ywyName,String ywyPwd) throws Exception{ 9 PrintWriter out=new PrintWriter(new File(filename)); 10 out.write("所有平台注册账号:"+"\r\n"); 11 out.write("超市注册账号:"+"\r\n"+csName+" "+csPwd+"\r\n"+"供货商注册账号:"+"\r\n"+ghsName+" "+ghsPwd+"\r\n"+"业务员注册账号:"+"\r\n"+ywyName+" "+ywyPwd+"\r\n"); 12 out.close(); 13 14 } 15 16 }
1 package com.test; 2 3 import org.apache.jmeter.config.Arguments; 4 import org.apache.jmeter.protocol.java.sampler.JavaSamplerClient; 5 import org.apache.jmeter.protocol.java.sampler.JavaSamplerContext; 6 import org.apache.jmeter.samplers.SampleResult; 7 8 9 /** 10 * Created by Administrator on 2017/8/28. 11 */ 12 public class PerformenceTest implements JavaSamplerClient { 13 private SampleResult results; 14 //private String orderNumber; 15 private String csName; 16 private String csPwd; 17 private String ghsName; 18 private String ghsPwd; 19 private String ywyName; 20 private String ywyPwd; 21 private String filename; 22 23 public static void main(String[] args) { 24 // TODO Auto-generated method stub 25 Arguments params = new Arguments(); 26 params.addArgument("filename","0"); 27 // params.addArgument("orderNumber", "0");//设置参数,并赋予默认值0 28 params.addArgument("csName", "0");//设置参数,并赋予默认值0 29 params.addArgument("csPwd", "0"); 30 params.addArgument("ghsName","0"); 31 params.addArgument("ghsPwd", "0"); 32 params.addArgument("ywyName","0"); 33 params.addArgument("ywyPwd", "0"); 34 35 JavaSamplerContext arg0 = new JavaSamplerContext(params); 36 PerformenceTest test = new PerformenceTest(); 37 test.setupTest(arg0); 38 test.runTest(arg0); 39 test.teardownTest(arg0); 40 } 41 // 设置传入的参数,可以设置多个,已设置的参数会显示到Jmeter的参数列表中 42 public Arguments getDefaultParameters() { 43 Arguments params = new Arguments(); 44 params.addArgument("filename", "0");//设置参数,并赋予默认值0 45 //params.addArgument("orderNumber", "0");//设置参数,并赋予默认值0 46 params.addArgument("csName", "0");//设置参数,并赋予默认值0 47 params.addArgument("csPwd","0"); 48 params.addArgument("ghsName", "0");//设置参数,并赋予默认值0 49 params.addArgument("ghsPwd","0"); 50 params.addArgument("ywyName", "0");//设置参数,并赋予默认值0 51 params.addArgument("ywyPwd","0"); 52 return params; 53 } 54 55 56 // 初始化方法,实际运行时每个线程仅执行一次,在测试方法运行前执行 57 public void setupTest(JavaSamplerContext arg0) { 58 results = new SampleResult(); 59 } 60 61 62 // 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 63 @Override 64 public SampleResult runTest(JavaSamplerContext arg0) { 65 // orderNumber = arg0.getParameter("orderNumber"); // 获取在Jmeter中设置的参数值 66 csName = arg0.getParameter("csName"); // 获取在Jmeter中设置的参数值 67 csPwd = arg0.getParameter("csPwd"); 68 ghsName = arg0.getParameter("ghsName"); // 获取在Jmeter中设置的参数值 69 ghsPwd= arg0.getParameter("ghsPwd"); 70 ywyName=arg0.getParameter("ywyName"); 71 ywyPwd=arg0.getParameter("ywyPwd"); 72 filename = arg0.getParameter("filename"); // 获取在Jmeter中设置的参数值 73 results.sampleStart();// jmeter 开始统计响应时间标记 74 try { 75 OutputService test = new OutputService(); 76 test.output(filename,csName,csPwd,ghsName,ghsPwd,ywyName,ywyPwd); 77 results.setSuccessful(true); 78 // 被测对象调用 79 } catch (Throwable e) { 80 results.setSuccessful(false); 81 e.printStackTrace(); 82 } finally { 83 results.sampleEnd();// jmeter 结束统计响应时间标记 84 } 85 return results; 86 } 87 88 89 // 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 90 public void teardownTest(JavaSamplerContext arg0) { 91 } 92 93 }
2.3 打jar包,步骤如图所示
2.4 然后把打好的JavaSampler.jar包cp到jmeter目录\lib\ext下
3、重启jmeter,加载刚导入的jar包
4、创建java请求,选择jar包的类名称,参数会自动加载出来,且默认值均为0,然后给各个参数赋值,下图是我给参数化了,也可以写具体的值
执行该请求,参数值会保存至指定的文件
执行结果如下图所示
