gatling新手必备资料
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
2.scala环境
地址: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/
文档:https://gatling.io/documentation/
入门:https://gatling.io/docs/current/quickstart/

---- bin 执行程序
---- ---- gatling.batwindows 环境运行
---- ---- gatling.sh liunx 环境运行
---- ---- recorder.batwindows 环境运行
---- ---- recorder.shliunx 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
</font>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。
3.环境搭建

</font>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:
<font size="3" color="#000000">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"))
}
