Test Writing: Catching Exceptions

Created By: Geoffrey Challen

/ Version: 2020.11.0

Create a method named catcher that takes, as a single parameter, a Faulter that has a fault method. You should call that fault method. If it generates no exception, you should return 0. If it generates a null pointer exception, you should return 1. If it throws an illegal argument exception, you should return 2. If it creates an illegal state exception, you should return 3. If it generates an array index out of bounds exception, you should return 4.

Test Design Challenge

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

• Provide a public class named TestCatcher 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
