Our Kotlin environment is built on top of our Java environment, giving you access to any libraries we have installed there, too.

For example, to run a JUnit test in Kotlin:

import org.junit.*;
import org.junit.runner.*;

fun main(args: Array<String>) {
  JUnitCore.main("Solution");
}

  @Test
  fun testNoop() {
    Assert.assertTrue(true);
  }
