Test Writing: CircularQueue Poll

Created By: Chris Taylor
/ Version: 2023.8.0

Implement the CircularQueue class that extends the AbstractCircularQueue class and implement the Object poll() method.

The following attributes are available from the AbstractCircularQueue class:

  • Object[] items - It's length determines the capacity of the queue. You may assume it is not null
  • boolean isEmpty - true when queue is empty
  • int frontIndex - index to the front of the queue
  • int backIndex - index to the back of the queue

Test Design Challenge

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

  • Provide a public class named TestCircularQueue 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
