| E1608. Refactor & write unit tests for [question_type].rb (eg. criterion.rb)
| | This wiki page is for the description of changes made under E1608OSS assignment for Spring 2016, CSC/ECE 517. |
| Contact: Zhewei Hu (zhu6@ncsu.edu)
| |
| What it does: In last summer we refactored different class of questions to make them follow the same design (you can take a look on Criterion.rb): there are 4 methods “edit”, “view_question_text”, “complete” and “view_completed_question” correspond to different views.
| |
| Files involved: criterion.rb, scale.rb, checkbox.rb, questionnaire_header.rb, upload_file.rb
| |
| 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

| 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 (“”).

| Cyclomatic complexity for complete is too high.
| |
| This problem can be solved by moving branches outside to other private methods. See source code above.
| |
| Similar codes in edit method are found in 2 other locations.
| |
| (questionnaire_header.rb and upload_file.rb)
| |
| Such code duplication can be eliminated by moving the identical part of the similar edit method to a new function, named edit_prefix(html, count) to their common superclass, which is Question (question.rb).
| |
| Here is the source code of the added edit_prefix method in question.rb:
| |
| | |
| def edit_prefix(ob, html)
| |
| html ='<tr>'
| |
| html+='<td align="center"><a rel="nofollow" data-method="delete" href="/questions/' +ob.id.to_s+ '">Remove</a></td>'
| |
| html+='<td><input size="6" value="'+ob.seq.to_s+'" name="question['+ob.id.to_s+'][seq]" id="question_'+ob.id.to_s+'_seq" type="text"></td>'
| |
| html+='<td><textarea cols="50" rows="1" name="question['+ob.id.to_s+'][txt]" id="question_'+ob.id.to_s+'_txt">'+ob.txt+'</textarea></td>'
| |
| html+='<td><input size="10" disabled="disabled" value="'+ob.type+'" name="question['+ob.id.to_s+'][type]" id="question_'+ob.id.to_s+'_type" type="text">''</td>'
| |
| end
| |
| The original code are commented out and insert the function call of the above function, html will be returned in the above function, see codes below:
| |
| | |
| def edit(count)
| |
| html = edit_prefix(self, html)
| |
| # html ='<tr>'
| |
| # html+='<td align="center"><a rel="nofollow" data-method="delete" href="/questions/' +self.id.to_s+ '">Remove</a></td>'
| |
| # html+='<td><input size="6" value="'+self.seq.to_s+'" name="question['+self.id.to_s+'][seq]" id="question_'+self.id.to_s+'_seq" type="text"></td>'
| |
| # html+='<td><textarea cols="50" rows="1" name="question['+self.id.to_s+'][txt]" id="question_'+self.id.to_s+'_txt">'+self.txt+'</textarea></td>'
| |
| # html+='<td><input size="10" disabled="disabled" value="'+self.type+'" name="question['+self.id.to_s+'][type]" id="question_'+self.id.to_s+'_type" type="text">''</td>'
| |
| html+='<td><!--placeholder (UnscoredQuestion does not need weight)--></td>'
| |
| html+='</tr>'
| |
| | |
| html.html_safe
| |
| end

| | |
| Similar codes in view_question_text method are found in 4 other locations.
| |
| (dropdown.rb, questionnaire_header.rb, text_response.rb, upload_file.rb)
| |
| The solution to this problem is the same as above one, below is the function added in the most common superclass, which is Question, that contains the common parts of the codes found in the view_question_text methods in all five classes.
| |
| def view_qt_prefix(ob, html)
| |
| html = '<TR><TD align="left"> '+ob.txt+ ' </TD>'
| |
| html += '<TD align="left">'+ob.type+'</TD>'
| |
| html += '<td align="center">'+ob.weight.to_s+'</TD>'
| |
| end
| |
| The original code are commented out and insert the function call of the above function, html will be returned in the above function, see codes below:
| |
| | |
| def view_question_text
| |
| html = view_qt_prefix(ob, html)
| |
| # html = '<TR><TD align="left"> '+self.txt+' </TD>'
| |
| # html += '<TD align="left">'+self.type+'</TD>'
| |
| # html += '<td align="center">'+self.weight.to_s+'</TD>'
| |
| html += '<TD align="center">Checked/Unchecked</TD>'
| |
| html += '</TR>'
| |
| html.html_safe
