Test Writing: Array Deep Copy

Created By: Geoffrey Challen

/ Version: 2020.10.0

Create a method named copy that accepts a nullable array of Items. It should return a deep copy of the passed array: meaning that the returned array should contain references to new copies of the objects contained in the original array. Item provides a copy constructor that you can use to make copies. If the passed array is null, copy should return null.

Test Design Challenge

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

• Provide a public class named TestCopier 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
