This wiki page is for the description of changes made under E1608 OSS assignment for Spring 2016, CSC/ECE 517. The assignment task is to refactor & write unit tests for [question_type].rb (eg. criterion.rb).


Problem Statement

Files related

Four models is related: criterion.rb, scale.rb, checkbox.rb, questionnaire_header.rb, upload_file.rb. There are 4 methods “edit”, “view_question_text”, “complete” and “view_completed_question” correspond to different views.

  • edit ~> when instructor add/edit new questions
  • view ~> when instructor view existed questions
  • complete ~> when students do peer reviews
  • view_completed_question ~> when student view existed peer reviews

Expertiza question types inheritance hierarchy

  • Choice question
    • Scored question
      • Scale
      • Criterion
    • Unscored question
      • Dropdown
      • CheckBox
  • TextResponse
    • TextArea
    • TextField
  • UploadFile

Files problem

There are some issues in each file, such as security, complexity, duplication, etc. And currently there is no unit tests for [question_type].rb.

Our contribution

  • 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 (“”).
