About Expertiza

Expertiza is an assignment/project management portal that can be used by both instructors and students for collaborative learning and feedback. It is an open-source project based on Ruby on Rails framework. It allows the instructors not only to create and customize new or existing assignments but also to create a list of topics the students can sign up for. Students can form teams to work on various projects and assignments. Expertiza also lets students peer-review other students' submissions, enabling them to work together to improve others' learning experiences.

Description and Testing

Our project deals with refactoring the answer.rb file. The code is responsible for doing the following tasks:

  • To design and implement an answsers_by_response method that returns answers in each response.
  • Get the answer model fully tested.

Files Involved

  • answer.rb
  • answer_spec

Running Tests

To successfully run answer_spec on the local machine, please run the below rspec command.

  rspec spec/answer_spec.rb


Project Description

The objective of the project is to refactor the following Ruby on Rails model classes in the existing project:- Answer Model on Expertiza.The model is designed to represent answers to questions in Expertiza. So, whenever anyone fills out a rubric, each “question” that is answered creates a new Answer object.

The task is to refactor the existing code present in the model file and implement them in a new repository. Since the project is implemented from scratch, there are various aspects of the project that have to be implemented and therefore unit test cases are implemented to test the implementation.


  • answers_by_question_for_reviewee_in_round:
 1. This method joins the responses, answers, response_maps, and questions table. 
 2. Then it applies a where clause to filter the results based on the given assignment_id, reviewee_id, q_id, and round parameters. 
 3. It retrieves answers and comments columns from the combined table. 


Code Snippet:

scope :by_question_for_reviewee_in_round, -> (assignment_id, reviewee_id, q_id, round) do

   joins(response: {map: :reviewer})
     .joins(:question)
     .where("review_maps.reviewed_object_id = ? AND
             review_maps.reviewee_id = ? AND
             answers.question_id = ? AND
             responses.round = ?", assignment_id, reviewee_id, q_id, round)
     .select(:answer, :comments)
 end


  • answers_by_question:
 This method joins the questions, answers, responses, and response_maps table. 
 Then it applies a where clause to filter the results based on the given q_id and assignment_id. 
 It retrieves the distinct answers and comments columns from the combined table. 

Code Snippet:

scope :by_question, -> (assignment_id, q_id) do

   joins(response: {map: :reviewer})
     .joins(:question)
     .where("review_maps.reviewed_object_id = ? AND
             answers.question_id = ?", assignment_id, q_id)
     .select(:answer, :comments)
     .distinct
 end

     .distinct
 end

Test Plan

We have implemented test cases using RSpec for different validation checks for answer.rb.

Code Snippet:

require '/Users/aw/Documents/Course Study Material/OODD/Program 3/spec/rails_helper.rb' require '/Users/aw/Documents/Course Study Material/OODD/Program 3/spec/spec_helper.rb'

RSpec.describe Answer, type: :model do

 describe ".by_question_for_reviewee_in_round" do
   let(:assignment) { create(:assignment) }
   let(:reviewer) { create(:user) }
   let(:reviewee) { create(:user) }
   let(:round) { 1 }
   let(:question) { create(:question, assignment: assignment) }
   let(:response_map) { create(:review_map, reviewed_object: assignment, reviewer: reviewer, reviewee: reviewee) }
   let(:response) { create(:response, map: response_map, round: round) }
   let!(:answer) { create(:answer, question: question, response: response) }
   it "returns the answer and comments for the specified question, reviewee, assignment, and round" do
     expect(Answer.by_question_for_reviewee_in_round(assignment.id, reviewee.id, question.id, round))
       .to match_array([{answer: answer.answer, comments: answer.comments}])
   end
 end


 describe ".by_question" do
   let(:assignment) { create(:assignment) }
   let(:reviewer) { create(:user) }
   let(:question) { create(:question, assignment: assignment) }
   let(:response_map) { create(:review_map, reviewed_object: assignment, reviewer: reviewer) }
   let(:response) { create(:response, map: response_map) }
   let!(:answer) { create(:answer, question: question, response: response) }
   it "returns the answer and comments for the specified question and assignment" do
     expect(Answer.by_question(assignment.id, question.id))
       .to match_array([{answer: answer.answer, comments: answer.comments}])
   end
 end

Code Snippet:

 describe ".by_question_for_reviewee" do
   let(:assignment) { create(:assignment) }
   let(:reviewer) { create(:user) }
   let(:reviewee) { create(:user) }
   let(:question) { create(:question, assignment: assignment) }
   let(:response_map) { create(:review_map, reviewed_object: assignment, reviewer: reviewer, reviewee: reviewee) }
   let(:response) { create(:response, map: response_map) }
   let!(:answer) { create(:answer, question: question, response: response) }
   it "returns the answer and comments for the specified question, reviewee, and assignment" do
     expect(Answer.by_question_for_reviewee(assignment.id, reviewee.id, question.id))
       .to match_array([{answer: answer.answer, comments: answer.comments}])
   end
 end

Code Snippet:

 describe ".by_response" do
   let(:response) { create(:response) }
   let!(:answer) { create(:answer, response: response) }
   it "returns the answer for the specified response" do
     expect(Answer.by_response(response.id)).to eq([answer.answer])
   end
 end

end

Test Execution

We divided the work among the teammates and started tackling the problems. We stubbed the data using the factory and mocked the method calls which were being done internally to get the desired output from the methods that were calling other methods internally.

Test Coverage

The summary helper spec file is newly created. This project increased testing coverage by 72.86% according to simplecov test.

Future Plan

The future scope of this project is to implement waitlist.rb model class that handles the functions related to adding/removing sign up teams to the waitlist for each topic. There are other instance methods in both sign_up_team.rb and sign_up_topic.rb that requires implementation. But, since they are dependent on other model classes, we have added them to our TODO list to implement them in the future.

Conclusion

We have refactored the code in the answer.rb file to return answers in each response. We have tested the model fully and attaching the video of the test cases in the submission.
