title: Android Studio + Spek integration
body: <p>I'm trying to add Spek testing framework to my Android Studio project. Following the instructions <a href="http://spekframework.org/docs/latest/" rel="noreferrer">Here</a>, I ended up adding the following to my module <code>build.gradle</code>:</p>
  
  <pre><code>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'
  </code></pre>
  
  <p>Then I annotated my test with <code>@RunWith(JUnitPlatform::class)</code></p>
  
  <p>However, when I try to run the test, I get:
  <code>org.junit.platform.commons.util.PreconditionViolationException: Cannot create Launcher without at least one TestEngine; consider adding an engine implementation JAR to the classpath</code></p>
  
  <p>Any idea what am I missing?</p>
