Test Writing: Object v. Reference Equality

Created By: Geoffrey Challen

/ Version: 2020.10.0

Implement a method named compare that accepts two Any? arguments. It should return 0 if both references are equal, 1 if both objects are equal, and -1 otherwise. Either reference can be null, so you'll need to handle those cases carefully!

Test Design Challenge

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

• Provide a public class named TestComparison 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
