Петли Гатлинга не работают

Вероятно, это что-то простое, но я просто не могу найти причину, по которой базовые циклы Гатлинга не работают ни в одном из моих тестов.

Независимо от того, как я пытаюсь определять циклы (счетчик повторений, продолжительность), мой упрощенный сценарий всегда выполняется один раз для каждого пользователя.

Код теста:

import io.gatling.core.Predef._
import io.gatling.http.Predef._

class RecordedSimulation extends Simulation {

  object Browse {

    val browse = exec(
      http("Getting category times")
        .get("http://localhost:8080/category/cat_1")
    )
  }

  val scn = scenario("My scenario").repeat(2000) {
    exec(Browse.browse)
  }

  setUp(
    scn.inject(atOnceUsers(10))
  )


}

вместо того, чтобы видеть 10x 2000 вызовов, я всегда вижу только 10 (равных "atOnceUsers):

Пожалуйста, попробуйте asLongAs

http://gatling.io/docs/1.5.6/user_documentation/tutorial/advanced_usage.html

asLongAs (session => session.getAttribute("username") != "user7") {exec}

Измените условие, как хотите. Это функция сеанса и работает ...

Не могли бы вы предоставить версию Gatling, которую вы использовали. Я использую 2.2.1, и ваш код работает для меня (я указал конец журнала - как вы можете видеть, есть 20000 запросов ОК)
