Test Writing: Mystery Class 1

Created By: Geoffrey Challen

/ Version: 2020.10.0

Ready for another reverse engineering challenge! This one is tough, so good luck! I'll provide a few hints:

• The class maintains two Int values
• One is set by the constructor
• Two methods manipulate the other
• The third method's return is based on a relationship between the two values

Have fun!

Test Design Challenge

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

• Provide a public class named TestMystery 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
