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 following test checks if the title is correct or not.

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

The following tests 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 following tests 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 following tests 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 folowing code tests 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 following code tests 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
