What’s wrong with it: You can click these [question_type].rb files listed above. These links will redirect to Code Climate. You need to fix these issues in each file, such as security, complexity, duplication, etc. And currently there is no unit tests for [question_type].rb. What needs to be done: Refactor these [question_type].rb files and fix issues. Keep the inputs and outputs of these methods (edit, view, complete, view_completed_question) the same as before. Write unit tests for [question_type].rb listed above. Create RSpec files for each question type in /spec/models/ folder Create multiple tests to check valid and invalid cases, such as input including special character double quote (“”).
