#  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

Hi, Payton Dwight

The problem was funny :) I'll report to Craig tomorrow.

To fix first error, that is

JavaTester.java:77: error: unreported exception IOException; must be caught or declared to be thrown
    Main.main(null);
             ^
1 error

The problem is that, when you catch IOException, you should not leave your main method declared throws

    // if you try catch Exception, remove throws from here
    // if you don't use try catch, then leave it here.
    public static void main(String[] args) throws IOException { // remove throws !!! 
        // write your code here
        Prompter prompt = new Prompter();
        String story = null;
        try {
            story = prompt.promptForStory();
        } catch (IOException e) {
            e.printStackTrace();
        }

The second error that comes is

 Bummer! Whoops looks like you forgot to remove the TODO's after you completed them. This helps everyone know it is done

That is the one you know how to fix right ? :)

When you remove all TODOs comes, the hardest one

Whoops looks like you didn't censor the words (2a). mCensoredWords contains 'dork', but it made it past somehow.

This one is impossible to solve, unless you know the answer :) Which I do, fortunately.

It has nothing to do with your code, it has to do with the testing.

Long story short, replace

            System.out.printf("Censored word (%s) found. Please try again. %n", word); // won't pass :( sorry

With

            System.out.printf("Censored word found. Please try again. %n");

And you will pass the challenge :)

If you want to know why it does not pass, let me know I'll try to explain.

So try it again, let's if it works now :)

I was having issues with the "Whoops, looks like you didn't censor the words..." error. The above mentioned changed solved it.

Hey Alexander,

Thank you for taking the time to write such a detailed response. I am curious as to why the last error arises in testing. Is it something to do with the way the tests are written?

So I don't know for sure, but he is testing all System.out.print for censored words,

because he has to write tests not knowing details of your implementation.

So if you put anywhere in your output

  System.out.printf("dork%n");

You will not pass.

Basically because they just look for censored words like "dork", and if they find such words, boom, you've got an error.

It is extremely hard to write tests for these challenges, I saw his code for Techdegree project 1, so yeah sometimes it is just hard to test the code that you don't know.

And that is exactly how he writes tests, inferring your structure.

Hi, I struggled for some time with this issue. I understand it is hard to write these tests. On the other hand, it is frustrating to be sitting with a local solution that 'works' but still 'failing' the challenge repeatedly.

Granted, failing the challenge several times lead to me re-evaluating parts of the solution and improving it. It also lead me to more thoroughly searching the forums. So, in the end, maybe it is good to be bumping your head against this for a while. However, had I not found this thread, who knows how long I would have sat with it.

My suggestion is to put more detailed instructions into the challenge or add more detailed 'tips' when errors are shown. For example, when displaying the censored word error, add a note to the reader to make sure not to include censored words in their prompts.

All things considered, it is more satisfying to solve the challenge and see the green success message after struggling with it, than it is to pass it the first time!
