karate - 如何使用 Gradle 构建系统运行 Karate 和 Gatling

Question

我正在尝试将 Karate 测试作为 Gatling 性能测试来运行。使用 Maven 时，我的整个设置工作得非常完美。然而我被迫使用 Gradle。当尝试在 Gradle 下运行时，会发生以下灾难。

了解可能导致 KarateAction 崩溃的任何想法。

MyAPI.scala

class MyAPI extends Simulation {
    val protocol = karateProtocol(
        "/myendpoint" -> Nil
    )

    val action = karateFeature("classpath:org/mycompany/karate/tests/myAPI.feature@test=myTag")

    setUp(
        scenario("my-api")
            .exec(action)
            .inject(rampUsersPerSec(1) to (5) during (5 seconds))
            .protocols(protocol)
    )
}

build.gradle

buildscript {
    ext {
        karateVersion = '0.9.2'
    }
}

apply plugin: 'scala'

configurations {
    gatling
}

dependencies {
    testCompile("com.intuit.karate:karate-apache:${karateVersion}")
    testCompile("com.intuit.karate:karate-mock-servlet:${karateVersion}")
    testCompile("com.intuit.karate:karate-junit4:${karateVersion}")
    testCompile("com.intuit.karate:karate-gatling:${karateVersion}")
    testCompile("net.masterthought:cucumber-reporting:3.8.0")

    gatling "org.scala-lang:scala-library:2.12.8"
    gatling "io.gatling:gatling-app:3.0.2"
    gatling "io.gatling.highcharts:gatling-charts-highcharts:3.0.2"
    gatling "com.intuit.karate:karate-gatling:${karateVersion}"
}

sourceSets {
    simulations {
        scala {
            srcDirs = ['src/test/java/org/mycompany/karate/perf']
        }
        resources {
            srcDirs = ['src/test/java/org/mycompany/karate/perf']
        }

        compileClasspath += configurations.gatling
    }
    test {
        resources {
            srcDir file('src/test/java')
            exclude '**/*.java'
        }
    }
}

test {
    systemProperty "karate.options", System.properties.getProperty("karate.options")
    systemProperty "karate.env", System.properties.getProperty("karate.env")
    outputs.upToDateWhen { false }
}

task gatlingRun(type: JavaExec) {
    description = 'Run Gatling Tests'
    new File("${buildDir}/reports/gatling").mkdirs()

    classpath = sourceSets.simulations.runtimeClasspath += configurations.gatling

    main = "io.gatling.app.Gatling"
    args = [
        '-s', 'org.mycompany.karate.perf.MyAPI',
        '-sf', 'src/test/java/org/mycompany/karate/perf',
        '-rf', "${buildDir}/reports/gatling"
    ]
    systemProperties System.properties
}

命令行

gradle gatlingRun

我有一个使用 scala 和 java 的 gradle 项目，并且必须创建一个 gradle 任务来将资源移动到正确的文件夹，以便使它们可用。

task copyResources(type: Copy) {
  from ("src/test/java/") {
    include "/**/*.feature"
    include "karate-config*.js"
    include "logback*.xml"
    include "/**/*.csv"
    include "/**/*.json"
  }
  into "$buildDir/classes/java/test/"

}
