Test Writing: Course Equality

Created By: Geoffrey Challen

/ Version: 2020.9.0

Create a public class named Course. Course should define a single public constructor that accepts three fields: a String (the department), a String (the course number, and yes, this must be a String) and an int (the enrollment). You are welcome to name these fields however you like! Your constructor should reject null departments and numbers and negative enrollments.

You do not need to provide any getters and setters! Instead, define a single method named equals. Your equals method accepts an Object as a single parameter. It should return true if the passed object is a Course and has the same values for the department and number, and false otherwise.

Test Design Challenge

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

• Provide a public class named TestCourse 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
