java - Gatling 2.0 throttle 不发送任何请求

Question

我正在尝试运行具有节流功能的简单 Gatling 场景，但没有请求发送到服务器。

我正在使用 Gatling 2.0.2、Java 1.8.0_25、Maven 3.2.3(都在 OS X 上运行)

我的代码是这样的:

object RequestHomePage {

  def apply() = {
      exec(http("Home Page Request")
        .get("http://my.page/home")
        .header("Accept", "application/xml,application/xhtml+xml")
  }
}

object HomePage {

  val executeScenario = scenario("Home Page Retrieval")
                                  exec(RequestHomePage())
}

class PerformaceSimulation extends Simulation {

  val maxResponseTime = 5000 // milliseconds

  val simultaneousUsers = atOnceUsers(100)

  setUp(HomePage.executeScenario
          .inject(atOnceUsers(100))
          .throttle(jumpToRps(1), holdFor(10 seconds))
    )
    .protocols(httpProtocol)
    .assertions(
      global.responseTime.max.lessThan(maxResponseTime)1
    )
}

输出如下:

有谁知道为什么 throttle(...) 不发送任何请求？ 谢谢

自 2.0.2 以来，已经修复了几个关于节流的错误。请升级到 2.1.4。
