Rampup within Closed Models

Gatling (Open-Source)
1

Hello,

Am using the closed model to create a stress test with 5 levels, but the first level users are not ruped up. They are launched concurently at the beginning.

`
scn.inject(
incrementConcurrentUsers(5)
.times(5)
.eachLevelLasting(30seconds)
.separatedByRampsLasting(10 seconds)
.startingFrom(0) )

`

Is there a way to apply the rampup on the first level users ?

Thanks in advance

scn.inject(

rampConcurrentUsers(0).to(5).during(10 seconds),
incrementConcurrentUsers(5)
.times(5)
.eachLevelLasting(30seconds)
.separatedByRampsLasting(10 seconds)
.startingFrom(5)
)

Thanks for your reply.
it doesn’t compile:

Error:(66, 20) not enough arguments for method inject: (implicit evidence$1: io.gatling.core.controller.inject.InjectionProfileFactory[Product with Serializable])io.gatling.core.structure.PopulationBuilder.
Unspecified value parameter evidence$1.
scnICM04.inject(
Error:(66, 20) could not find implicit value for evidence parameter of type io.gatling.core.controller.inject.InjectionProfileFactory[Product with Serializable]
scnICM04.inject(

My code is as follow:

import io.gatling.core.Predef.{incrementConcurrentUsers, rampConcurrentUsers, _}
import io.gatling.http.Predef._
import scala.concurrent.duration._

class HttpSimulation extends Simulation {

  val scn = scenario("Custom Scenario")
    .exec(
      http("gatling demo site")
        .get("[http://databcomputer-ase.gatling.io](http://databcomputer-ase.gatling.io)")
    )

  setUp(
    scn.inject(
      rampConcurrentUsers(0) to(5) during(10 seconds),
      incrementConcurrentUsers(5)
        .times(5)
        .eachLevelLasting(30 seconds)
        .separatedByRampsLasting(10 seconds)
        .startingFrom(5)
    )
  )
}

Right.

Then don’t use this meta profile and configure each step individually from constantConcurrentUsers and rampConcurrentUsers
