内容简介：性能测试Gatling入门教程

Gatling 是一个功能强大的负载测试工具。它是为易用性、可维护性和高性能而设计的,它能生成丰富多彩的报告，包含测试案例中收集的所有指标,该功能似乎比 JMeter更好,因此我在实际压力测试中选用Gatling。

Gatling安装

从Gatling 官网下载后解压即可,执行bin目录下的gatling.bat或者gatling.sh即可运行,要先安装好jdk配置好环境变量。

快速教程

推荐使用Intelj idea + maven archetype插件来搭建开发环境,Gatling采用了Scala DSL语言,首先要配置好Scala环境，在Idea的插件库搜索Scala并安装，然后从

Scala 官网下载scala SDK,打开Idea的project structure，找到Global Library那一栏，点加号添加下载的Scala SDK.

执行Maven命令创建项目骨架:

mvn archetype:generate -DinteractiveMode=false -DarchetypeGroupId=io.gatling.highcharts -DarchetypeArtifactId=gatling-highcharts-maven-archetype -DgroupId=com.ezlippi  -DartifactId=gatling.test  -Dversion=1.0

生成如下项目结构：在src/test/scala目录下新建一个继承Simulation类的测试类,在里面写测试方法:

 class OpenApiSimulation extends Simulation {

  val httpConf = http
    .baseURL("https://someUrl")
    .acceptHeader("application/json")
    .contentTypeHeader("application/json")
    .userAgentHeader("Mozilla/5.0 (Windows NT 5.1; rv:31.0) Gecko/20100101 Firefox/31.0")

 //forever表示一直执行,具体写法可以参考：https://gatling.io/docs/2.3/general/simulation_setup/
  val scn = scenario("com.ezlippi.OpenApiSimulation")
      .forever(exec(http("request_1")
        .get("")))

//只执行一次
//  val scn = scenario("com.ezlippi.OpenApiSimulation")
//      .exec(http("request_1").get("/646df17616081148d3e679"))

  //立刻注入100个用户
  val injectStrategy = atOnceUsers(100)


  
  setUp(
    scn.inject(injectStrategy)
  ).protocols(httpConf).maxDuration(Duration.apply(10, TimeUnit.MINUTES))

执行测试脚本

如果通过maven命令执行测试脚本，需要在pom文件中配置gatling-maven-plugin，simulationClass表示要执行的测试类,resultsFolder是测试报告存放的路径，

disableCompiler执行的时候是否禁止编译,因为我写完测试类后就右键编译把scala文件编译好了，执行maven命令时没必要再次编译,插件配置如下:

 <plugin>
	<groupId>io.gatling</groupId>
	<artifactId>gatling-maven-plugin</artifactId>
	<version>2.2.4</version>
	<configuration>
		<!-- 测试脚本 -->
		<simulationClass>com.ezlippi.OpenApiSimulation</simulationClass>
		<!-- 结果输出地址 -->
		<resultsFolder>gatling</resultsFolder>
		<disableCompiler>true</disableCompiler>
	</configuration>
</plugin>

然后执行mvn gatling:execute就可以执行用例了,输出结果如下:

================================================================================
2018-01-22 21:34:27                                           0s elapsed

          waiting: 100    / active: 0      / done:0

================================================================================


================================================================================
2018-01-22 21:34:32                                           4s elapsed

> request_1                                                (OK=4789   KO=0     )
================================================================================

查看测试报告

打开gatling目录已时间戳结尾的文件夹下的index.html文件就可以查看报告了，结果非常明显。

直接通过maven配置

如果通过archetype插件创建项目骨架失败了，那可以直接新建maven工程，然后添加如下内容到pom文件中:

 <?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

在src/test/resources目录下添加logback的配置文件logback.xml,内容如下:

 <?xml version="1.0" encoding="UTF-8"?>
<configuration>
	<appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
		<encoder>
			<pattern>%d{HH:mm:ss.SSS} [%-5level] %logger{15} - %msg%n%rEx</pattern>
			<immediateFlush>false</immediateFlush>
		</encoder>
	</appender>

	<root level="WARN">
		<appender-ref ref="CONSOLE" />
	</root>

</configuration>

然后执行mvn gatling:execute就大功告成了。
