Gatling - install & start

Posted on | In | |

基于Scala 开发的开源免费性能压测工具。主要用于测量基于HTTP的服务器，比如Web应用程序，RESTful服务等。
方方面面的原因，准备用Gatling做性能测试，对这个工具做一个简单的研究。

Install

去官网下载： http://gatling.io/download/
下载之后，解压到相应的目录中去。

  • bin 目录下有2个脚本，gatling和recorder， gatling用来运行测试， recorder用来启动录制脚本的UI的。
  • conf 目录是关于Gatling自身的一些配置。
  • lib 目录是Gatling自身依赖的库文件。
  • results 目录用来存放测试报告的。
  • target
  • user-files
    • bodies
    • data 数据目录，csv参数文件存放在这里
    • simulations 测试脚本（所有的脚本都在这里）

Recorder

运行bin目录下的’recorder.bat’，打开Recorder Window。

录制之前要先设置浏览器用Gatling Recorder’s proxy，录制之后，保存脚本。录制一个搜索：

    val uri2 = "www.baidu.com"
    val uri3 = "http://baidu.com"

	val scn = scenario("RecordedSimulation")
		.exec(http("request_0")
			.get(uri3 + "/")
			.headers(headers_0)
			.resources(http("request_1")
			.get("/img/baidu_jgylogo3.gif"),
            http("request_2")
			.get("/img/bd_logo1.png")))
		.pause(4)
		.exec(http("request_3")
			.get("/s?ie=utf-8&f=8&rsv_bp=1&rsv_idx=1&ch=&tn=baidu&bar=&wd=gatling&rn=&oq=&rsv_pq=e632af2400018ab7&rsv_t=21efo2auHiH8VwtAPnYwISgfAskcOJ5NLsAxSJh2B%2BZEb6LFvXLa%2BPVXxwc&rqlang=cn")

            http("request_5")
			.get("/aladdin/img/dic3/iconall.gif")))

	setUp(scn.inject(atOnceUsers(1))).protocols(httpProtocol)
}

录制功能应该一般都不太会用到。

Run

运行bin目录下的’gatling.bat’
