You have this in the bag man. Just remember that since you are instantiating the post object, it has no description to get. Therefore, you just need to enter in some arbitrary description.

        ForumPost post = new ForumPost(author, forum.getTopic(), "blah blah blah");

You can also enter in anything you want for the title as well and the test will pass because it is just looking for a String. When I completed this I just made up a title and description to pass with the author because I felt that a title is different than the topic. For example, a forum post could be setup like:

Topic: Java Title: Method Overloading Author: Hasan Nagaria Description: A discussion about overloading methods in Java and their uses.

Hope this helps.

Thanks a lot, these questions are really frustrating sometimes the way they are structured really frustrates me.
