Library with a bunch of usefull functions that extend Gatling DSL and make your performance better.
If you are using TinkoffCreditSystems/gatling-template.g8, you already have all dependecies in it. Gatling Template Project
Add dependency with version that you need
libraryDependencies += "ru.tinkoff" %% "gatling-picatinny" % "0.5.0"
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")
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")
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'
- 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 )
}

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.
To test your changes use sbt test
