我在kotlin测试中使用spek非常新.使用spek时,在logcat上出现以下错误.我不知道为什么我得到这个

我对gradle文件有以下依赖关系
testImplementation 'junit:junit:4.12'
testImplementation 'org.jetbrains.spek:spek-api:1.1.0-beta3'
testImplementation 'org.jetbrains.spek:spek-junit-platform-engine:1.1.0-beta3'
testImplementation 'org.junit.platform:junit-platform-runner:1.0.0-M3'
测试文件

import org.junit.runner.RunWith
@RunWith(JUnitPlatform::class)
class ExampleUnitTest : Spek({
val x = 2
val y = 3
given("x = $x and y = $y") { …我很难配置基于JUnit Jupiter(5)的测试环境.那里有两个不同的错误:
WARNING: TestEngine with ID 'spek' failed to discover tests
org.junit.platform.commons.util.PreconditionViolationException: Could not load class with name...
Exception in thread "main" java.lang.NoSuchMethodError: org.junit.platform.launcher.Launcher.execute(Lorg/junit/platform/launcher/LauncherDiscoveryRequest;)V
at com.intellij.junit5.JUnit5IdeaTestRunner.startRunnerWithArgs(JUnit5IdeaTestRunner.java:61)...
配置如下.
主要build.gradle:
apply plugin: 'org.junit.platform.gradle.plugin'
buildscript {
ext.kotlin_version = '1.1.4-3'
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.0-beta5'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath "org.junit.platform:junit-platform-gradle-plugin:1.0.0"
classpath "de.mannodermaus.gradle.plugins:android-junit5:1.0.0"
}
}
allprojects {

}
}

}
模块 …
我正在尝试将Spek测试框架添加到我的Android Studio项目中.按照说明在这里,我最终添加以下内容到我的模块build.gradle:
testCompile 'org.jetbrains.spek:spek-api:1.1.5'
testCompile 'junit:junit:4.12'
testCompile "org.junit.platform:junit-platform-runner:1.0.0"
testRuntimeOnly 'org.jetbrains.spek:spek-junit-platform-engine:1.1.5'
然后我注释了我的测试 @RunWith(JUnitPlatform::class)
但是,当我尝试运行测试时,我得到:
org.junit.platform.commons.util.PreconditionViolationException: Cannot create Launcher without at least one TestEngine; consider adding an engine implementation JAR to the classpath
知道我错过了什么吗？
我试图将我的测试区分为单元测试和集成测试。我的想法是使用新的JUnit5批注@Tag("unit")，该批注对我的JUnit测试非常有效，但我无法使其与Spek一起使用。
我现在的课程是：
data class MyObject(val value: Int)
我的测试：
@Tag("unit")
object MyObjectTest {
@Test
fun checkEquality() {
val o1 = MyObject(1)
assertEquals(o1, o1)
}
}
与我的build.gradle具有：
task utest(type: Test) {
outputs.upToDateWhen { false }
useJUnitPlatform {
includeEngines 'junit-jupiter', 'junit-vintage', 'spek'
includeTags 'unit'
excludeTags 'performance', 'integration', 'functional'
}
testLogging {
events "passed", "skipped", "failed"
}
}
当我执行utest时，这可行。但是，使用Spek进行相同操作时：
@Tag("unit")
object MyObjectSpek : Spek({
given("an Object") {
val o1 = MyObject(1)
it("should be equal to itself") {
assertEquals(o1, o1)
}
}
}) …我想要一个通用的测试装置：
@RunWith(JUnitPlatform::class)
abstract class BaseSpek: Spek({
beforeGroup {println("before")}
afterGroup {println("after")}
})
现在我想使用该规范：
class MySpek: BaseSpek({
it("should xxx") {}
})
但由于无参数BaseSpek构造函数，我遇到了编译错误。实现我需要的正确方法是什么？
我在spek试图找到测试时遇到了崩溃.我尝试过很多不同的版本和样本配置.我从命令行运行.Gradle 4.0,mac osx.任何帮助,将不胜感激!
这是错误:
