Gatling Picatinny

Build Status Maven Central

Table of contents

General info

Library with a bunch of usefull functions that extend Gatling DSL and make your performance better.

Installation

Using Gatling Template Project

If you are using TinkoffCreditSystems/gatling-template.g8, you already have all dependecies in it. Gatling Template Project

Install manualy

Add dependency with version that you need

libraryDependencies += "ru.tinkoff" %% "gatling-picatinny" % "0.6.0"

Usage

config

The only class the you need from this module is SimulationConfig. It could be used to attach some default variables such as intensity, baseUrl, baseAuthUrl and some others to your scripts. Also it provides functions to get custom variables fom config.

Import:

import ru.tinkoff.gatling.config.SimulationConfig._

Using default variables:

import ru.tinkoff.gatling.config.SimulationConfig._

val testPlan: Seq[OpenInjectionStep] = List(
    rampUsersPerSec(0).to(intensity).during(rampDuration),
    constantUsersPerSec(intensity).during(stageDuration)
)

Using functions to get custom variable:

simulation.conf

stringVariable: "FOO",
intVariable: 1,
doubleVariable: 3.1415,
duration: {
    durationVariable: 3600s
}
import ru.tinkoff.gatling.config.SimulationConfig._

val stringVariable      = getStringParam("stringVariable")
val intVariable         = getIntParam("intVariable")
val doubleVariable      = getDoubleParam("doubleVariable")
val durationVariable    = getDurationParam("duration.durationVariable")

feeders

This module contains vast number of random feeders. They could be used as regular feeders and realize common needs, i.e random phone number or random digit. Now it supports feeders for dates, numbers and digits, strings, uuids, phones. There we'll provide some examples, other feeders can be used same way. Now it supports feeders for dates, digits, strings, uuids, phones.

import ru.tinkoff.gatling.feeders._

//creates feeder with name 'randomString' that gets random string of length 10
val stringFeeder = RandomStringFeeder("randomString", 10)

//creates feeder with name 'digit' that gets random Int digit
val digitFeeder = RandomDigitFeeder("digit")

//creates feeder with name 'uuid' that gets random uuid
val uuidFeeder = RandomUUIDFeeder("uuid")

influxdb

This module includes Annotation manager. It can write annotations to InfluxDB that denote start and end of simulation and could be shown in Grafana for example.

Import:

import ru.tinkoff.gatling.influxdb.Annotations

For using you should simply add with Annotations for your simulation class:

class LoadTest extends Simulation with Annotations{
    //some code
}

To see annotations in grafana you need this two queries, where Perfix is from gatling.data.graphite.rootPathPrefix in gatling.conf:

SELECT "annotation_value"  FROM "${Prefix}" where "annotation" = 'Start'
SELECT "annotation_value"  FROM "${Prefix}" where "annotation" = 'Stop'

profile

Features:

  • Load profile configs from HOCON or YAML files
  • Common traits to create profiles for any protocol
  • HTTP profile as an example

Import:

import ru.tinkoff.gatling.profile._

Using:

HOCON configuration example:

{
  name: test-profile
  profile: [
    {
      name: request-a
      url: "http://test.url"
      probability: 50.0
      method: get
    },
    {
      name: request-b
      url: "http://test.url"
      probability: 50.0
      method: post
      body:  "{\"a\": \"1\"}"
    }
  ]
}

YAML configuration example:

name: test-profile
profile:
  - name: request-a
    url: "http://test.url"
    probability: 50
    method: get
  - name: request-b
    url: "http://test.url"
    probability: 50
    method: post
    body: "{\"a\": \"1\"}"

Simulation setUp

  class test extends Simulation {
      val profileConfigName = "profile.conf"
      val someTestPlan      = constantUsersPerSec(intensity) during stageDuration
      val httpProtocol      = http.baseUrl(baseUrl)
      val config: HttpProfileConfig = new ProfileBuilder[HttpProfileConfig].buildFromYaml(profileConfigName)
      val scn: ScenarioBuilder = config.toRandomScenario
      
      setUp(
          scn.inject(
            atOnceUsers(10)
          ).protocols(httpProtocol)
        ).maxDuration(10 )
  }

utils

jwt

Features:

  • Generates a JWT token using a json template and stores it in a Gatling session, then you can use it to sign requests.

Import:

import ru.tinkoff.gatling.utils.jwt._

Using:

First you need to prepare jwt generator. For example

val jwtGenerator = jwt("HS256", jwtSecretToken)
    .defaultHeader 
    .payloadFromResource("jwtTemplates/payload.json")

This will generate tokens with headers:

{
  "alg": "HS256",
  "typ": "JWT"
}

Payload will be generated from json template, templating is done using Gatling EL

{
  "userName": "${randomString}",
  "date": "${simpleDate}",
  "phone": "${randomPhone}"
}

Also the JWT generator has a DSL allowing you to:

jwt("HS256", secret)
.header("""{"alg": "HS256","typ": "JWT", "customField": "customData"}""") //use custom headers from string, it must be valid json
.headerFromResource("jwtTemplates/header.json") //use src/test/resources/jwtTemplates/header.json as header template
.defaultHeader //use default jwt header, algorithm from jwt("HS256", secret), template: {"alg": "$algorithm","typ": "JWT"}
.payload("""{"userName": "${randomString}","date": "${simpleDate}","phone": "${randomPhone}"}""") //use custom payload from string, it must be valid json
.payloadFromResource("jwtTemplates/payload.json") //use src/test/resources/jwtTemplates/payload.json as payload template

For sign requests add this to your scenario chain:

    .exec(_.setJwt(jwtGenerator, "jwtToken")) //generates token and save it to gatling session as "jwtToken"
    .exec(addCookie(Cookie("JWT_TOKEN", "${jwtToken}").withDomain(jwtCookieDomain).withPath("/"))) //set JWT_TOKEN cookie for subsequent requests

example

See the examples in the examples/ directory.

You can run these from the sbt console with the commands project example and then gatling:testOnly ru.tinkoff.load.example.SampleSimulation.

Ensure that the correct InfluxDB parameters are specified in gatling.conf and influx.conf.

Testing

To test your changes use sbt test.
