使用Gatling的油门功能时，Karate Gatling会抛出异常而不会生成任何报告

Question

在做POC时，我遇到了一个问题。 Karate Gatling在使用Gatling进行模拟注射方面效果很好。但是，当我尝试使用Gatlings油门功能时，会抛出一些例外情况。执行完成说 - 模拟com.perffeatures.ExecuteThrottle在150秒内完成。在此之后抛出异常。报告未生成

这是我尝试过的场景

class ExecuteThrottle extends Simulation {
  before {
    println("Execution of load test started for throttle test")
  }
  val protocol = karateProtocol("/api/users?delay=3" -> pauseFor("post" -> 10))
  val perfscenario3 = scenario("Feature_1").exec(karateFeature("classpath:com/perffeatures/perfscenario3.feature"))

  setUp(
    perfscenario3.inject(
      constantUsersPerSec(1) during (10 minutes)
    ).protocols(protocol)
  ).throttle(
    reachRps(10) in (30 seconds),
    holdFor(1 minute),
    jumpToRps(25),
    holdFor(1 minute)
  ).assertions(
    global.responseTime.max.between(100, 5000),
    global.failedRequests.percent.is(0)
  ).maxDuration(20 minutes)

  after {
    println("Done with the load test execution for throttle test")
  }
}

执行完成后，我得到这样的异常

    Simulation com.perffeatures.ExecuteThrottle completed in 150 seconds
    Done with the load test execution for throttle test

是的，这是（唯一的）已知的Karate-Gatling集成限制，截至目前并在文档中明确提到：qazxsw poi

这在技术上是可行的（但需要一些工作），并将在未来的版本中提供。

我正在寻找能够尽快做出贡献的人。
