This is a sample questionnaire project. The UI is pretty bare bones. I used MUI to take advantage of some ready made components.

To run the code:

• npm install
• npm run dev

The application will open up at http://localhost:3000

The questions are obtained from question-data.json. The questions can be added/removed and the navigation steps will change.

The input types supported are in the components folder.

On submit a post request is sent to a mock "submit" api.

Added a few unit test cases for components

Assumptions:

• The id for each question object in the question-data.json file HAS to be incremental.
• Random ids are not supported. The application will not work as the consective numbers are used to increment and decrement the page id.
• Validation is done only when the "required" field in the question object is set to true

Extras:

• A summary page is shown with all the selected answers for review before submit.
