Test Writing: Dog Is Older

Created By: Geoffrey Challen

/ Version: 2021.3.0

Create a public class Dog that stores a single double age set by the constructor. (Reject negative ages using assert.) Dog should also provide a single class method named isOlder. isOlder should accept two Dog instances and return true if the first is older than the second, and false otherwise. You should also assert that both passed instances are not null.

So here is how Dog should work:

Test Design Challenge

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

• Provide a public class named TestDog 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 Java's assert method
