JMeter简单使用

简单介绍

Apache JMeter是一个开源、纯Java编写，设计来为应用程序进行功能行为测试以及性能衡量的软件。

官网

Apache JMeter may be used to test performance both on static and dynamic resources, Web dynamic applications.
It can be used to simulate a heavy load on a server, group of servers, network or object to test its strength or to analyze overall performance under different load types.

Apache JMeter features include:

• Ability to load and performance test many different applications/server/protocol types:
  • Web - HTTP, HTTPS (Java, NodeJS, PHP, ASP.NET, …)
  • SOAP / REST Webservices
  • FTP
  • Database via JDBC
  • LDAP
  • Message-oriented middleware (MOM) via JMS
  • Mail - SMTP(S), POP3(S) and IMAP(S)
  • Native commands or shell scripts
  • TCP
  • Java Objects
• Full featured Test IDE that allows fast Test Plan recording (from Browsers or native applications), building and debugging.
• CLI mode (Command-line mode (previously called Non GUI) / headless mode) to load test from any Java compatible OS (Linux, Windows, Mac OSX, …)
• A complete and ready to present dynamic HTML report
• Easy correlation through ability to extract data from most popular response formats, HTML, JSON , XML or any textual format
• Complete portability and 100% Java purity.
• Full multi-threading framework allows concurrent sampling by many threads and simultaneous sampling of different functions by separate thread groups.
• Caching and offline analysis/replaying of test results.
• Highly Extensible core:
  • Pluggable Samplers allow unlimited testing capabilities.
  • Scriptable Samplers (JSR223-compatible languages like Groovy and BeanShell)
  • Several load statistics may be chosen with pluggable timers.
  • Data analysis and visualization plugins allow great extensibility as well as personalization.
  • Functions can be used to provide dynamic input to a test or provide data manipulation.
  • Easy Continuous Integration through 3^rd party Open Source libraries for Maven, Gradle and Jenkins.

简单示例：

下面进行压力测试，模拟100用户同时调用下的运行情况，由于此次关注点在如何使用JMeter，服务接口的内部实现就略过，可自主实现。

前期准备

• 准备好要测试的服务接口，此次测试地址如下，该接口有两个方法，接收一个整数：

  
  接口方法

• 下载并运行JMeter：
  jmeter下载地址
  这里测试环境为windows，下载后解压后运行jmeter.bat

建立和测试计划

1. 首先选择测试计划，添加线程组：

   
   添加线程组
   

   添加后进行配置：

   这里配置100并发，只执行一次。

2. 创建Http请求并配置：

   下面配置的是调用/add/{num}使用路径变量形式的url，如果是不是路径参数的话，去掉url后面的${num}，在下面Parameters页面添加名称为num的参数，值不用设置，同样使用随后我们创建的随机变量配置来生成即可。

3. 添加随机变量生成配置

5. 选中测试计划并执行后，可以到结果查看树查看执行情况：

这样一个简单的使用JMeter进行测试的例子就完成了。
