测试环境配置：Android + JUnit 5 + Mockito + Spek + Kotlin

我很难配置基于JUnit Jupiter（5）的测试环境。 我有两个不同的错误：

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 { repositories { google() jcenter() maven { url "http://dl.bintray.com/jetbrains/spek" } } } junitPlatform { filters { engines { include 'spek' } } } 

模块build.gradle ：

 apply plugin: 'com.android.application' apply plugin: 'kotlin-android' apply plugin: 'kotlin-android-extensions' apply plugin: 'de.mannodermaus.android-junit5' android { compileSdkVersion 26 buildToolsVersion "26.0.0" defaultConfig { ... testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" } ... compileOptions { targetCompatibility JavaVersion.VERSION_1_8 sourceCompatibility JavaVersion.VERSION_1_8 } } dependencies { implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version" implementation 'com.android.support:appcompat-v7:26.0.2' implementation 'com.android.support:recyclerview-v7:26.0.2' testImplementation 'org.jetbrains.spek:spek-api:1.1.4' testImplementation 'org.jetbrains.spek:spek-junit-platform-engine:1.1.4' testImplementation junit5() // testImplementation 'org.junit.jupiter:junit-jupiter-engine:5.0.0' not needed when using the one above testImplementation 'org.junit.platform:junit-platform-runner:1.0.0' testImplementation 'org.mockito:mockito-core:2.8.47' testImplementation 'com.nhaarman:mockito-kotlin-kt1.1:1.5.0' testCompileOnly "de.mannodermaus.gradle.plugins:android-junit5-embedded-runtime:1.0.0" } 

这个配置应该基于https://github.com/aurae/android-junit5 。 但是我也试过没有它。

有没有人设法找到这些库的依赖关系的工作配置？
