#  This is essentially what I am testing 
1.  The user is prompted for a new string template (the one with the double underscores in it).

  a. The prompter class has a new method that prompts for the story template, and that method is called.

2.  The user is then prompted for each word that has been double underscored.

   a. The answer is checked to see if it is contained in the censored words.
      User is continually prompted until they enter a valid word

3.  The user is presented with the completed story

I can give you a clue :)

The problem is that in method promptForWord(String phrase) you don't use phrase, i.e. don't print it while prompting

That means that user cannot know what exactly he should enter, 'name' , or 'noun' or ...

That is why when you change

        System.out.println("Please input your words!");

To

        System.out.printf("Please input %s", phrase);

Tester will see phrase and you will be good to go
