gatling搭建与使用

谁借莪１个温暖的怀抱￠ 2022-02-26 04:40 354阅读 0赞

一、搭建环境与下载  
gatling是基于scala环境，但是scala是基于java的，需要二种环境，  
1.java环境  
地址：[https://www.runoob.com/java/java-environment-setup.html][https_www.runoob.com_java_java-environment-setup.html]  
2.scala环境  
地址：[https://www.scala-lang.org/download/][https_www.scala-lang.org_download]

直接下载安装，不需要配置环境变量。验证`scala -version`

3.下载gatling  
地址：[https://gatling.io/download/][https_gatling.io_download]  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzMyNDQ3MzAx_size_16_color_FFFFFF_t_70 1]文档：[https://gatling.io/documentation/][https_gatling.io_documentation]  
入门：[https://gatling.io/docs/current/quickstart/][https_gatling.io_docs_current_quickstart]

-gatling-charts-highcharts-bundle-3.0.3-bundle
    ---- bin 执行程序
    ---- ---- gatling.bat  windows 环境运行
    ---- ---- gatling.sh liunx 环境运行
    ---- ---- recorder.bat  windows 环境运行
    ---- ---- recorder.sh  liunx 环境运行
    ---- conf 配置信息
    ---- lib 依赖包
    ---- user-files 用户文件
    ---- ---- bodies 用来存放请求的body数据
    ---- ---- data 数据目录，csv参数文件存放在这里
    ---- ---- simulations 测试脚本
    #####Run:
    > ```bash
    > #Linux/Unix执行脚本
    > >$GATLING_HOME/bin/gatling.sh
    > #Windows执行脚本
    > >%GATLING_HOME%\bin\gatling.bat

使用bat脚本运行下是此画面。

二、springboot与gatling结合进行压测  
1.需要在IDEA安装scala插件  
2.安装scala SDK 由于步骤一 我们已经安装完毕，不需要安装，只需要重新配置。

4.编写测试脚本  
每一个 Gatling 测试都要继承 Simulation 类，在里面你可以使用Gatling Scala DSL 来声明一个场景列表。这里的目标是运行 30 个客户端，同时发送 1000 次请求  
项目目录结构：

package com.anoyi.test
    
    import io.gatling.core.scenario.Simulation
    import io.gatling.core.Predef._
    import io.gatling.http.Predef._
    import scala.concurrent.duration.FiniteDuration
    import scala.concurrent.duration.Duration
    import java.util.concurrent.TimeUnit
    
    class ApiGatlingSimulationTest extends Simulation {
    
      val scn = scenario("AddAndFindPersons").repeat(1000, "n") {
        exec(
          http("AddPerson-API")
            .post("http://localhost:8080/persons")
            .header("Content-Type", "application/json")
            .body(StringBody("""{"firstName":"John${n}","lastName":"Smith${n}","birthDate":"1980-01-01", "address": {"country":"pl","city":"Warsaw","street":"Test${n}","postalCode":"02-200","houseNo":${n}}}"""))
            .check(status.is(200))
        ).pause(Duration.apply(5, TimeUnit.MILLISECONDS))
      }.repeat(1000, "n") {
        exec(
          http("GetPerson-API")
            .get("http://localhost:8080/persons/${n}")
            .check(status.is(200))
        )
      }
     setUp(scn.inject(atOnceUsers(30))).maxDuration(FiniteDuration.apply(10, "minutes"))
    
    }
