Create a class called, LinkedInUserTest. The LinkedInUserTest class contains the JUnit test methods (annotated with @Test).

Error check removing a connection o Create a unit test which creates three LinkedIn users. Assign the first username as han, the second username as luke, and the last username as Leia Connect han with luke Call the removeConnection method, attempting to remove the connection between han and Leia. Assert that the method throws a LinkedInException with the message, You are NOT connected with this user Sorting Create a unit test which creates three LinkedIn users.
