Test Design Challenge

You're challenge is to write tests for this problem described above.

• Provide a public class named TestWhisperer with a single non-private class method named test that accepts no arguments and does not return a value.
• If the implementation of the class described above is incorrect, your test method should throw an exception.
• If it is correct, do not throw an exception.
• You may want to use Kotlin's assert or check methods
