Question

当我尝试使用空手道运行Gatling性能测试时，我在错误日志中得到以下内容。

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：


            <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

这是我的scala文件：

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：

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

中提供的解决方案

Crashed with 'j.l.NullPointerException' when i try to run karate-gatling test reports

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。

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

我试图运行另一个与项目相关的功能文件，但给出了相同的错误，因此尝试了一个视频教程之后的简单测试-https://www.youtube.com/watch?v=RrRhndl-osY

有人可以帮忙吗？

Answer 1

对于其他遇到此问题的人来说，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。

这可能是因为在 Windows 上，Java bin 文件夹未添加到系统 PATH。有关更多详细信息，请参阅以下主题。
