title: JUnit test in Kotlin
body: <p><strong>Warning: I'm a huge noob to TDD and Kotlin.</strong></p>
  
  <p>I've found good code snippets on the web for writing JUnit tests in Kotlin, but when I copy and paste, IntelliJ does not automagically import <code>kotlin.test.*</code> or <code>org.junit.Test</code>.  Typically in Eclipse, when I copy and paste code snippets like this, the IDE can figure out where these libraries are in my underlying java install.  Figured Kotlin/IntelliJ would be the same.</p>
  
  <p>In the below screenshot, any idea why I cannot import test libraries?  Do they need to be added explicitly to my path?  Do I need to put these under a <code>test</code>, rather than the <code>src</code> folder? </p>
