Question

我正在尝试使用限制功能运行简单的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（全部在OS X上运行）

我的代码如下所示：

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：

有谁知道为什么会限制（...）不发送任何请求？感谢

Answer 1

自2.0.2以来，有一些关于限制的错误修复。请升级到2.1.4。

Answer 2

在Gatling的用户组（https://groups.google.com/forum/#!topic/gatling/QW212U3hDus）与@ stephane-landelle讨论后，解决方案是使用：

.inject(constantUsersPerSec(numberOfUsers) during(loadDuration seconds))

in

setUp(scenario
  .inject(constantUsersPerSec(numberOfUsers) during(loadDuration seconds))
)
.protocols(httpProtocolConfig)
.assertions(
  global.responseTime.max.lessThan(maxResponseTime)
)

重要提示：关于节流（http://gatling.io/docs/2.1.4/general/simulation_setup.html#throttling）的Gatling 2.1.4文档中的第一个注释对于理解常量rps和节流（...）作为请求上限的函数至关重要每秒。
