Need to run scenario based on user parameter using Aslongas in gatling

Hi , I m new to Gatling. I need to run the scenario based on user’s input condition. I m using Aslongas but m facing the error, where the scenario is running continuously does not stop when it meets the condition.

val count = new java.util.concurrent.atomic.AtomicInteger(0)



val epicScenario = scenario("scenario").feed(userFeeder)
  .asLongAs(count.getAndIncrement() <= 3)  {
      exec(LoginFlow())
        .exec(Actionflow)
        .exec(session =>
          session.set(count,count+1)
        )

}

Kindly help with the above one, If anyone have an idea.

Hi,

“count.getAndIncrement() <= 3” is executed only once. Being true the first time, it stays true for ever.

A solution could be to make sure it is evaluated each time by making it a function : session => count.getAndIncrement() <= 3

However, if you only intend to loop multiple times, you might find the usage of repeat simpler:

.repeat(n) {
exec(LoginFlow())
.exec(Actionflow)
}

Thanks Guillaume. I have got it with the below code:

val scn = scenario("scenario").feed(userFeeder)
  .exec { session => session.set("counter", 0) }
  .asLongAs(condition = _ => counter.getAndIncrement() < Config.NUM_USERS, exitASAP = false) {
    exec(LoginFlow())
      .exec(Actionflow)
  }

Thanks
