Hands-On Object-Oriented Programming with Kotlin

Gradle with Groovy

You should add the path to junit-platform-gradle-plugin to a classpath, and add test dependencies to the appropriate section in the build.gradle file. As a result of this, your build.gradle file will look as follows:

buildscript {    dependencies {        classpath 'org.junit.platform:junit-platform-gradle-plugin:1.0.0'    }}apply plugin: 'org.junit.platform.gradle.plugin'junitPlatform {    filters {        engines {            include 'spek'        }    }}repositories {    maven { url "http://dl.bintray.com/jetbrains/spek" }}dependencies {    testCompile 'org.jetbrains.spek:spek-api:1.1.5'    testRuntime 'org.jetbrains.spek:spek-junit-platform-engine:1.1.5'}
