Test Writing: Add One Function

Created By: Geoffrey Challen

/ Version: 2020.8.0

For this homework you'll write a simple function, a reusable piece of code that allows us to build more complex computer programs.

We're going to start simple. Declare and implement a function called addOne. Your function should accept a single int argument and return the result of adding one to its argument.

Test Design Challenge

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

• Provide a 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 Java's assert method
