问题描述
在进行POC时，我面临一个问题.空手道加特林(Karate Gatling)在使用加特林(Gatling)进行仿真注射时效果很好.但是，当我尝试使用Gatlings节流功能时，它会抛出一些异常.执行完成的话是-Simulation com.perffeatures.ExecuteThrottle在150秒内完成.此后将引发异常.报告未生成
While doing a POC, I am facing an issue. Karate Gatling works well in doing injections for simulations using Gatling. However, when I tried to use the Gatlings throttle feature, it throws a few exceptions. The executions completed saying - Simulation com.perffeatures.ExecuteThrottle completed in 150 seconds. The exception is thrown after this. Report is not generated
这是我尝试过的情况
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，我会收到类似的异常
I am getting exceptions like this after the execution completion
Simulation com.perffeatures.ExecuteThrottle completed in 150 seconds
Done with the load test execution for throttle test

推荐答案
是的，这是(唯一的)已知的Karate-Gatling集成的模仿，并在文档中明确提到: https://github.com/intuit/karate/tree/master/karate-gatling#limitations
Yes, this is (the only?) known lmitation of Karate-Gatling integration as of now and clearly mentioned in the documentation: https://github.com/intuit/karate/tree/master/karate-gatling#limitations
从技术上讲这是可行的(但需要做一些工作)，并将在以后的版本中提供.
This is technically possible (but needs some work) and will be made available in a future release.
我正在寻找可以更快做出贡献的人.
And I'm looking for someone who can contribute sooner.
对于零暂停时间，您可以使用 Nil
For zero pause times you can use Nil
val protocol = karateProtocol(
"/cats/{id}" -> Nil,
"/cats" -> pauseFor("get" -> 15, "post" -> 25)
)
