Test Writing: Counter Object

Created By: Geoffrey Challen

/ Version: 2020.9.0

Define a public class named Counter with a single public instance method named increment. increment takes no parameters and returns an int. The first time it is called it should return 0, the next 1, the next 2, and so on. Each instance of Counter should maintain its own private counter.

Test Design Challenge

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

• Provide a public class named TestCounter 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
