 ## Adding another test case
 1. Add another `assert` statement after the first one that checks for the cube

 ## Conclusion
 You've seen one way to test your Scala code. You can learn more about
 ScalaTest's FunSuite on the [official website](https://www.scalatest.org/getting_started_with_fun_suite). You can also check out other testing frameworks such as  [ScalaCheck](https://www.scalacheck.org/) and [Specs2](https://etorreborre.github.io/specs2/).
