Dynamically adding scenarios based on loop

Obviously, we won’t help with your jenkins part.

To reduce verbosity (as I don’t think that is the subject at hand), let’s start with this code:

class Sample extends Simulation {
  private val httpProtocol = http
    .baseUrl("https://sample.com")

  val scnLaunchApp = scenario("LaunchApp").exec(
    // ...
  )
  val scniosDeviceApps = scenario("iosDeviceApps").exec(
    // ...
  )

  setUp(
      scnLaunchApp.inject(atOnceUsers(1)),
      scniosDeviceApps.inject(atOnceUsers(1)),
    ).protocols(httpProtocol)
}

Do you know that setUp may take a List[PopulationBuilder] as arguments?

  val injections = List(
    scnLaunchApp.inject(atOnceUsers(1)),
    scniosDeviceApps.inject(atOnceUsers(1)),
  )

  setUp(injections).protocols(httpProtocol)

Do you know that you can build a list of elements that are optional?

val sample = List(
  Some(1),
  None,
  Some(2),
  None,
  None,
  Some(3)
)
// val sample: List[Option[Int]] = List(Some(1), None, Some(2), None, None, Some(3))

Then, you can flatten it

sample.flatten
// res: List[Int] = List(1, 2, 3)

In another hand, you can get an option for an environment variable with sys.env.get("ENV_NAME") or an option of system property with sys.props.get("prop.name").

So, you can write something like:

  val injections = List(
    sys.props.get("launchApp").filter(_ == "true").map(_ => scnLaunchApp.inject(atOnceUsers(1))),
    sys.props.get("iosDeviceApps").filter(_ == "true").map(_ => scniosDeviceApps.inject(atOnceUsers(1))),
  ).flatten

  setUp(injections).protocols(httpProtocol)

To achieve what you want.

Is that clear?

I (really do) hope that helps.

Cheers!
