空手道加特林在使用加特林的油门功能时抛出异常，没有生成报告

Question

在进行POC时，我面临一个问题。空手道加特林在使用加特林进行模拟注射时效果很好。然而，当我尝试使用Gatlings节流功能时，它抛出了一些例外。执行完成了Say-Simulation com。性能特征。ExecuteThrotle在150秒内完成。在此之后将引发异常。未生成报告

这就是我尝试过的场景

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")
  }
}

在执行完成后，我会遇到这样的异常情况

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

Answer 1

是的，这是（唯一的？）目前已知的空手道-加特林融合的情况，并在文件中明确提到：https://github.com/intuit/karate/tree/master/karate-gatling#limitations

这在技术上是可能的（但需要一些工作），并将在未来的版本中提供。

我在找一个能更快做出贡献的人。

对于零暂停时间，您可以使用Nil

val protocol = karateProtocol(
  "/cats/{id}" -> Nil,
  "/cats" -> pauseFor("get" -> 15, "post" -> 25)
)
