Before you start:

• Try not to read ahead.
• Do one task at a time. The trick is to learn to work incrementally.
• Make sure you only test for correct inputs, there is no need to test for invalid inputs for this kata.
• Test First!

Description

Quiz Builder is a console application that allows you to create and fill quizzes. This application is currently in development, so some of its features are already implemented but other need to be implemented.

Current features

• Create quiz
  • Supports the next kind of questions:
    • Text
    • Date
    • Pick one option (similar to a radio input element in HTML)
  • Each question type has its own associated validations, for example:
    • The question type TEXT supports the validations REQUIRED and MIN_LENGTH
  • Given a created quiz, it is possible to fill the values for its questions

Pending features to implement

Question types

1. Add support for a new question type called NUMERIC
2. Associate the next validations REQUIRED and MIN to it. Remember that you need to convert the values to int

Validations

You'll notice that several validations are implemented but they are not being applied.

3. Add the required code to apply validations when the user is filling the quiz.

4. Add support for new kind of validations for question's answer.

   • Text validations
     • Max length
     • Only uppercase text

Enhance the Show Quiz menu action

We want to enhance this action because currently the question information is not usefully,

5. Enhance that logic to show the question title and answer. REFACTORING

Persistence

Currently all the information is stored on memory, that means quizzes are lost after finishing the application. Sometime ago, a member of the dev team did a research about persisting information in a JSON file, you can check and run the JsonPersistence.java file which was the result of the research.

6. Given the JsonPersistence.java file, try to reuse that code to implement the quiz persistence in a JSON file and also load a quiz given a JSON file. Don't forget to include the respective action menu for this.

Menu

We don't like how the action menu (Menu.java) is implemented, it has too much IFs; there should be a better way to implement it,

7. Provide a better alternative that helps in the maintainability .

Unit testing

There are some unit tests that will help you during the refactoring.

8. Include more scenarios.
9. Additionally, there are some features that are failing, please fix them and add the related tests.
