pass command line argument to simulation telling it which scenario to run

Gatling (Open-Source)

Hi guys, I’m looking for a way to pass the scenario name I want to run in simulation via the command line./

For example:
The command line command and arguments look like this:

mvn gatling:test -Dgatling.simulationClass=performance.com.api.simulation.Simulation -DUSERS=10 -DRAMP_DURATION=100 -DDURATION=2400 -DTESTNAME=“scnCreateUser”

I am running this in Jenkins and I want to be able to configure the scenario to run from there and not have to hard code it





these are my different files:

request file(MSXPlatformUser.scala)

package ...

import ...

object MSXPlatformUser extends BaseSimulation{

  def randomString(length: Int):String = {
    rnd.alphanumeric.filter(_.isLetter).take(length).mkString
  }

  def getPagedTenants: ChainBuilder = {
    feed(custPageIteratorFeeder)
      .exec(http("Get Existing Tenants Paged")
...

      )
  }

  def createNewUser: ChainBuilder = {
    feed(custRandGroupTenantFeeder)
      .exec(http("Create New User")
...
      )
  }

  def getNewUser: ChainBuilder = {
    exec(http("Retrieve New User")
...
    )
  }
}

Thank you Vu! I got it to work well partly. And it works very well! Next I want to pass an argument with a list. For example -Dtestsimulationstorun=test5,test25,test7. Any idea if this is possible?

I’m glad you made it work.

Below is the gist of what I have currently. You may want to add more Scala codes for your specific need. Hope that helps!

`

class Test extends Simulation {

def getOption(key: String, default: String): String = { java.lang.System.getProperty(key, default) }

val simScenarios = getOption(…) /** this is your testsimulationstorun /
val simUrls = getOption(…) /* this is your target server urls */

def testSimulation = {

val testScenarios = Map(

“test1” → Set(
test1.inject(…)
),
“test2” → Set(
test2.inject(…)
),
“test3” → Set(
test3.inject(…)
)
)

simScenarios
.split(",|\+")
.foldLeftSet[io.gatling.core.structure.PopulationBuilder]((sim, scn) => sim ++ testScenarios(scn.trim()))
.toVector
}

def testProtocol = {

val testBaseUrls: Vector[String] = simUrls.split(",|\+").map(_.trim()).toVector

val testHeaders: Map[String, String] = Map(
“Connection” → “close”
)

http
.baseURLs(testBaseUrls: _*)
.disableFollowRedirect
.headers(testHeaders)
}

setUp(testSimulation: _*).protocols(testProtocol)

}
