E1850 Write unit tests for review response map

Expertiza

It is an open source software created by North Carolina State University's students. It works on ruby on rails framework. This platform allows instructor to post notification about tests and assignments and also allows students to view grades, submit assignments, find teammates etc.

Problem Statement

1.Create a new file named review_response_map_spec.rb under spec/models folder
2.Write RSpec unit tests to make the path coverage above 90%.
3.Coverage as many edge cases as you can.
4.Achieve as high branch coverage as you can. We will use the mutant-rspec gem to measure test thoroughness and fault-finding capability of your tests.

Test Plan

The get_title method

describe '#get_title' do
    it 'returns the title' do
      expect(review_response_map.get_title).to eql("Review")
    end
  end

The questionnaire method

describe '#questionnaire' do
    it 'returns questionnaire' do
      allow(assignment).to receive(:review_questionnaire_id).and_return(1)
      allow(Questionnaire).to receive(:find_by).with(id: 1).and_return(questionnaire)
      expect(review_response_map.questionnaire.id).to eq(1)
    end
  end 

The export_fields method

 describe '.export_fields' do
    it 'returns list of strings "contributor" and "reviewed by"' do
      expect(ReviewResponseMap.export_fields "").to eq(["contributor", "reviewed by"])
    end
  end

The delete method

describe '#delete' do
    it 'deletes the review response map' do
      allow(review_response_map.response).to receive(:response_id).and_return(1)
      allow(FeedbackResponseMap).to receive(:where).with(reviewed_object_id: 1).and_return([feedback_response_map])
      allow(feedback_response_map).to receive(:delete).with(nil).and_return(true)
      allow(MetareviewResponseMap).to receive(:where).with(reviewed_object_id: review_response_map.id).and_return([meta_review_response_map])
      allow(meta_review_response_map).to receive(:delete).with(nil).and_return(true)
      allow(review_response_map).to receive(:destroy).and_return(true)
      expect(review_response_map.delete).to be true
    end
  end

The get_responses_for_team_round method

describe '.get_responses_for_team_round' do
    context 'when team doesnt exist' do
      it 'returns empty response' do
        team = instance_double('AssignmentTeam').as_null_object
        allow(team).to receive(:id).and_return(false)
        expect(ReviewResponseMap.get_responses_for_team_round team, 1).to eql([])
      end
    end 
     context 'when team exists' do
      it 'returns the responses for particular round' do
        team = instance_double('AssignmentTeam', :id=>1)
        round = 1
        allow(ResponseMap).to receive(:where).with(reviewee_id: 1, type: "ReviewResponseMap").and_return([response_map, response_map2])
        expect(ReviewResponseMap.get_responses_for_team_round(team, round).length).to eql(2)
      end
    end
  end

The show_feedback method

describe '#show_feedback' do
    context 'when no response is present or response is nil' do
      it 'returns nil' do
        db1 = instance_double("Response").as_null_object
        expect(review_response_map.show_feedback db1).to be(nil)
      end
    end
  end
end

Testing Framework

We used RSpec framework to test the given file.RSpec is a 'Domain Specific Language' (DSL) testing tool written in Ruby to test Ruby code.It is a behavior-driven development (BDD) framework which is extensively used in the production applications. The basic idea behind this concept is that of Test Driven Development (TDD) where the tests are written first and the development is based on writing just enough code that will fulfill those tests followed by refactoring. It contains its own mocking framework that is fully integrated into the framework based upon JMock.The simplicity in the RSpec syntax makes it one of the popular testing tools for Ruby applications. The RSpec tool can be used by installing the rspec gem which consists of 3 other gems namely rspec-core, rspec-expectation and rspec-mock.
