GatlingSystem-akka.actor.default-dispatcher-2错误-运行空手道加特林测试时因'j.l.NullPointerException'崩溃 [英] GatlingSystem-akka.actor.default-dispatcher-2 error - crashed with 'j.l.NullPointerException' when running Karate Gatling test

问题描述

当我尝试用空手道运行Gatling性能测试时，我在错误日志中得到以下内容.

When I try to run a Gatling performance test with Karate, I get the following in the error log.

Simulation perf.SVTKarateSimulation started...
17:55:28.277 [GatlingSystem-akka.actor.default-dispatcher-2][ERROR][Action.scala:71] c.i.k.g.KarateAction - 'classpath:com/TCEU/KarateTests/Test.feature' crashed with 'j.l.NullPointerException', forwarding to the next one

这是我的pom文件的外观:

This is how my pom file looks:

            <plugin>
                <groupId>io.gatling</groupId>
                <artifactId>gatling-maven-plugin</artifactId>
                <version>3.0.4</version>
                <configuration>
                    <simulationsFolder>src/test/java</simulationsFolder>
                    <includes>
                        <include>perf.SVTKarateSimulation</include>
                    </includes>
                    <jvmArgs>
                        <jvmArg>-Dfile.encoding=UTF-8</jvmArg>
                    </jvmArgs>
                </configuration>
            </plugin>    

并使用Karate-Gatling 0.9.5.RC4

And using Karate-Gatling 0.9.5.RC4

这是我的scala文件:

This is how my scala file:

package perf

import com.intuit.karate.gatling.PreDef._
import io.gatling.core.Predef._
import scala.concurrent.duration._
import io.gatling.http.Predef._

class SVTKarateSimulation extends Simulation {

  val create = scenario("Get api").exec(karateFeature("classpath:com/TCEU/KarateTests/test.feature"))

  setUp(
    create.inject(rampUsers(10) during (10 seconds)))

}

还有test.feature文件:

And the test.feature file:

Feature: Gatling test

    Background: 
    * url 'https://regres.in'

    Scenario: Get api

        Given path '/api/users/2'
        When method GET
        Then status 200

我查看了

崩溃为"jlNullPointerException"，当我尝试运行空手道加特林测试报告时

以及 https://github.com/intuit/karate/issues/404

但是其中提供的解决方案也无济于事.

But the solutions provided in that does not help either.

我正在使用Windows 10和Eclipse版本:2019-09 R(4.13.0).

I am using Windows 10 with Eclipse Version: 2019-09 R (4.13.0).

我尝试运行另一个与项目相关的功能文件，但给出了相同的错误，因此在视频教程之后尝试了一个简单的测试-

I tried to run another project related feature file but that gave the same error so tried a simple test following a video tutorial - https://www.youtube.com/watch?v=RrRhndl-osY

有人可以帮忙吗?

推荐答案

对于其他面临此问题的人来说，解决方案是使pom.xml与相同版本的Karate保持一致.我的空手道得分为0.9.5.RC4，而空手道阿帕奇的得分为0.9.4.当我将它们都设置为0.9.5.RC4时，我没有遇到这些问题.确保pom.xml一致.

For the benefit of anyone else who faces this issue, the solution is to keep your pom.xml consistent with same version of Karate. My karate-gatling was 0.9.5.RC4 where as karate-apache was 0.9.4. When I made them both 0.9.5.RC4, I did not face these issues. Make sure pom.xml is consistent.
