E1848 Write unit tests for assignment team

For this progect, the goal is to wirte up unit tests for assignment_team.rb

Project Introduction

assignment_team.rb is the child class of team.rb. It is used to manage student teams in assignments. There are not enough unit tests for this model in expertiza. The following tests are added to assignment_team.rb in this project.

Unit Test Steps

Create unit test cases in the assignment_team_spec.rb

run rspec spec/models/assignment_team_spec.rb under expertiza directory

the rspec outputs the number of test cases that are passed and those that are failed.

Unit Test Cases

Testing include?

2 test cases are designed to test this method:

1. The team includes a given participant.

      let(:assignment_team) { build(:assignment_team, id: 1, parent_id: 1, name: "full name") }
      let(:participant1) { build(:participant, id: 2, user: user) }
      it "returns true" do
        allow(assignment_team).to receive(:add_participants).with(participant1)
        expect(assignment_team.includes?(participant1))
      end

2. The team doesn't include a given participant.

      let(:assignment_team) { build(:assignment_team, id: 1, parent_id: 1, name: "full name") }
      let(:participant1) { build(:participant, id: 2, user: user) }
      let(:participant2) { build(:participant, id: 3) }
      it "returns false" do
        allow(assignment_team).to receive(:add_participants).with(participant1)
        expect(assignment_team.includes?(participant2))
      end

Testing parent_model
