Gatling基于Scala开发的压测工具,我们可以通过录制自动生成脚本,也可以自己编写脚本,大家不用担心,首先脚本很简单常用的没几个,另外gatling封装的也很好我们不需要去专门学习Scala语法,当然如果会的话会更好。

脚本示例

import io.gatling.core.Predef._
import io.gatling.http.Predef._
import scala.concurrent.duration._
class BaiduSimulation extends Simulation {
//设置请求的根路径
val httpConf = http.baseURL("https://www.baidu.com")
/*
运行100秒 during 默认单位秒,如果要用微秒 during(100 millisecond)
*/

val scn = scenario("BaiduSimulation").during(100){
exec(http("baidu_home").get("/"))
}
//设置线程数
// setUp(scn.inject(rampUsers(500) over(10 seconds)).protocols(httpConf))
setUp(scn.inject(atOnceUsers(10)).protocols(httpConf))
}

脚本编写

Gatling脚本的编写主要包含下面三个步骤

  • http head配置
  • Scenario 执行细节
  • setUp 组装

我们以百度为例,进行第一个GET请求测试脚本的编写,类必须继承 Simulation

  1. 配置下head,只是简单的请求下百度首页,所以只定义下请求的base url,采用默认的http配置即可 //设置请求的根路径 val httpConf = http.baseURL("https://www.baidu.com")
  2. 声明Scenario,指定我们的请求动作

    val scn = scenario("BaiduSimulation").
    exec(http("baidu_home").get("/"))

    scenario里的参数:scenario name
    exec()里的参数就是我们的执行动作,http("本次请求的名称").get("本次http get请求的地址")

  3. 设置并发数并组装

    //设置线程数
    setUp(scn.inject(atOnceUsers(10)).protocols(httpConf))

    atOnceUsers:立马启动的用户数,可以理解为并发数

这样我们一个简单的脚本就完成了,可以运行看下效果。

Injection -- 注入

注入方法用来定义虚拟用户的操作

setUp(
scn.inject(
nothingFor(4 seconds), // 1
atOnceUsers(10), // 2
rampUsers(10) over(5 seconds), // 3
constantUsersPerSec(20) during(15 seconds), // 4
constantUsersPerSec(20) during(15 seconds) randomized, // 5
rampUsersPerSec(10) to 20 during(10 minutes), // 6
rampUsersPerSec(10) to 20 during(10 minutes) randomized, // 7
splitUsers(1000) into(rampUsers(10) over(10 seconds)) separatedBy(10 seconds), // 8
splitUsers(1000) into(rampUsers(10) over(10 seconds)) separatedBy atOnceUsers(30), // 9
heavisideUsers(1000) over(20 seconds) // 10
).protocols(httpConf)
)
  1. nothingFor(duration):设置一段停止的时间
  2. atOnceUsers(nbUsers):立即注入一定数量的虚拟用户 setUp(scn.inject(atOnceUsers(50)).protocols(httpConf))
  3. rampUsers(nbUsers) over(duration):在指定时间内,设置一定数量逐步注入的虚拟用户 setUp(scn.inject(rampUsers(50) over(30 seconds)).protocols(httpConf))
  4. constantUsersPerSec(rate) during(duration):定义一个在每秒钟恒定的并发用户数,持续指定的时间 setUp(scn.inject(constantUsersPerSec(30) during(15 seconds)).protocols(httpConf))
  5. constantUsersPerSec(rate) during(duration) randomized:定义一个在每秒钟围绕指定并发数随机增减的并发,持续指定时间 setUp(scn.inject(constantUsersPerSec(30) during(15 seconds) randomized).protocols(httpConf))
  6. rampUsersPerSec(rate1) to (rate2) during(duration):定义一个并发数区间,运行指定时间,并发增长的周期是一个规律的值 setUp(scn.inject(rampUsersPerSec(30) to (50) during(15 seconds)).protocols(httpConf))
  7. rampUsersPerSec(rate1) to(rate2) during(duration) randomized:定义一个并发数区间,运行指定时间,并发增长的周期是一个随机的值 setUp(scn.inject(rampUsersPerSec(30) to (50) during(15 seconds) randomized).protocols(httpConf))
  8. heavisideUsers(nbUsers) over(duration):定义一个持续的并发,围绕和海维赛德函数平滑逼近的增长量,持续指定时间(译者解释下海维赛德函数,H(x)当x>0时返回1,x<0时返回0,x=0时返回0.5。实际操作时,并发数是一个成平滑抛物线形的曲线) setUp(scn.inject(heavisideUsers(50) over(15 seconds)).protocols(httpConf))
  9. splitUsers(nbUsers) into(injectionStep) separatedBy(duration):定义一个周期,执行injectionStep里面的注入,将nbUsers的请求平均分配 setUp(scn.inject(splitUsers(50) into(rampUsers(10) over(10 seconds)) separatedBy(10 seconds)).protocols(httpConf))
  10. splitUsers(nbUsers) into(injectionStep1) separatedBy(injectionStep2):使用injectionStep2的注入作为周期,分隔injectionStep1的注入,直到用户数达到nbUsers setUp(scn.inject(splitUsers(100) into(rampUsers(10) over(10 seconds)) separatedBy atOnceUsers(30)).protocols(httpConf))
循环
val scn = scenario("BaiduSimulation").
exec(http("baidu_home").get("/"))

上面的测试代码运行时只能跑一次,为了测试效果,我们需要让它持续运行一定次数或者一段时间,可以使用下面两个方式:

  • repeat repeat(times,counterName) times:循环次数 counterName:计数器名称,可选参数,可以用来当当前循环下标值使用,从0开始 val scn = scenario("BaiduSimulation").repeat(100){ exec(http("baidu_home").get("/")) }
  • during during(duration, counterName, exitASAP) duration:时长,默认单位秒,可以加单位milliseconds,表示毫秒 counterName:计数器名称,可选。很少使用 exitASAP:默认为true,简单的可以认为当这个为false的时候循环直接跳出,可在 循环中进行控制是否继续 /* 运行100秒 during 默认单位秒,如果要用微秒 during(100 millisecond) */ val scn = scenario("BaiduSimulation").during(100){ exec(http("baidu_home").get("/")) }
POST请求

post参数提交方式:

  • JSON方式

    import io.gatling.core.Predef._
    import io.gatling.core.scenario.Simulation
    import io.gatling.http.Predef._
    class JsonSimulation extends Simulation {
    val httpConf = http.baseURL("http://127.0.0.1:7001/tst")
    //注意这里,设置提交内容type
    val headers_json = Map("Content-Type" -> "application/json")
    val scn = scenario("json scenario")
    .exec(http("test_json") //http 请求name
    .post("/order/get") //post url
    .headers(headers_json) //设置body数据格式
    //将json参数用StringBody包起,并作为参数传递给function body()
    .body(RawFileBody("request.txt"))
    setUp(scn.inject(atOnceUsers(10))).protocols(httpConf)
    }
  • Form方式

    import io.gatling.core.Predef._
    import io.gatling.http.Predef._
    class FormSimulation extends Simulation {
    val httpConf = http
    .baseURL("http://computer-database.gatling.io")
    //注意这里,设置提交内容type
    val contentType = Map("Content-Type" -> "application/x-www-form-urlencoded")
    //声明scenario
    val scn = scenario("form Scenario")
    .exec(http("form_test") //http 请求name
    .post("/computers") //post地址, 真正发起的地址会拼上上面的baseUrl http://computer-database.gatling.io/computers
    .headers(contentType)
    .formParam("name", "Beautiful Computer") //form 表单的property name = name, value=Beautiful Computer
    .formParam("introduced", "2012-05-30")
    .formParam("discontinued", "")
    .formParam("company", "37"))
    setUp(scn.inject(atOnceUsers(1)).protocols(httpConf))
    }
  • RawFileBody

    import io.gatling.core.Predef._
    import io.gatling.core.scenario.Simulation
    import io.gatling.http.Predef._
    class JsonSimulation extends Simulation {
    val httpConf = http.baseURL("http://127.0.0.1:7001/tst")
    //注意这里,设置提交内容type
    val headers_json = Map("Content-Type" -> "application/json")
    val scn = scenario("json scenario")
    .exec(http("test_json") //http 请求name
    .post("/order/get") //post url
    .headers(headers_json) //设置body数据格式
    //将json参数用StringBody包起,并作为参数传递给function body()
    .body(RawFileBody("request.txt"))
    setUp(scn.inject(atOnceUsers(10))).protocols(httpConf)
    }

    txt的文件内容为JSON数据,存放目录/resources/bodies

Feed 动态参数

Gatling对参数的处理称为Feeder[供料器],支持主要有:

  • 数组 val feeder = Array( Map("foo" -> "foo1", "bar" -> "bar1"), Map("foo" -> "foo2", "bar" -> "bar2"), Map("foo" -> "foo3", "bar" -> "bar3"))
  • CSV文件 val csvFeeder = csv("foo.csv")//文件路径在 %Gatling_Home%/user-files/data/
  • JSON文件 val jsonFileFeeder = jsonFile("foo.json") //json的形式: [ { "id":19434, "foo":1 }, { "id":19435, "foo":2 } ]
  • JDBC数据 jdbcFeeder("databaseUrl", "username", "password", "SELECT * FROM users")
  • Redis

    可参看官方文档http://gatling.io/docs/2.1.7/session/feeder.html#feeder

    使用示例:

    import io.gatling.core.Predef._
    import io.gatling.core.scenario.Simulation
    import io.gatling.http.Predef._
    import scala.concurrent.duration._
    /**
    * region请求接口测试
    */

    class DynamicTest extends Simulation {
    val httpConf = http.baseURL("http://127.0.0.1:7001/test")
    //地区 feeder
    val regionFeeder = csv("region.csv").random
    //数组形式
    val mapTypeFeeder = Array(
    Map("type" -> ""),
    Map("type" -> "id_to_name"),
    Map("type" -> "name_to_id")).random
    //设置请求地址
    val regionRequest =
    exec(http("region_map").get("/region/map/get"))
    //加载mapType feeder
    .feed(mapTypeFeeder)
    //执行请求, feeder里key=type, 在下面可以直接使用${type}
    .exec(http("province_map").get("/region/provinces?mType=${type}"))
    //加载地区 feeder
    .feed(regionFeeder)
    //region.csv里title含有provinceId和cityId,所以请求中直接引用${cityId}/${provinceId}
    .exec(http("county_map").get("/region/countties/map?mType=${type}&cityId=${cityId}&provinceId=${provinceId}"))
    //声明scenario name=dynamic_test
    val scn = scenario("dynamic_test")
    .exec(during(180){ regionRequest
    })
    //在2秒内平滑启动150个线程(具体多少秒启动多少线程大家自己评估哈,我这里瞎写的)
    setUp(scn.inject(rampUsers(150) over (2 seconds)).protocols(httpConf))
    }

    注意:通过下面的代码只会第一次调用生成一个随机数,后面调用不变

    exec(http("Random id browse")
    .get("/articles/" + scala.util.Random.nextInt(100))
    .check(status.is(200))

    Gatling的官方文档解释是,由于DSL会预编译,在整个执行过程中是静态的。因此Random在运行过程中就已经静态化了,不会再执行。应改为Feeder实现,Feeder是gatling用于实现注入动态参数或变量的,改用Feeder实现:

    val randomIdFeeder = 
    Iterator.continually(Map("id" ->
    (scala.util.Random.nextInt(100))))

    feed(randomIdFeeder)
    .exec(http("Random id browse")
    .get("/articles/${id}"))
    .check(status.is(200))

    feed()在每次执行时都会从Iterator[Map[String, T]]对象中取出一个值,这样才能实现动态参数的需求。

谢谢支持

外部可以调用Galting的接口吗?访问他的测试报告等一些数据

丫滴 回复

测试报告是静态页面,你配个Nginx就可以访问了

为什么我按照楼主步骤,反复试了几次,还是报错,完整日志如下:
