Unit Test Cases

Testing has_submissions?

Includes 4 testcases:

1.The team doesn't submit any file or link.

      let(:team2) { build(:assignment_team, id: 2, parent_id: 1, name: "team2", submitted_hyperlinks: "") }
      it "no file or no link" do
        expect(team2.has_submissions?).to eq(false)
      end

2.The team submits a link instead of files.

      let(:team1) { build(:assignment_team, id: 1, parent_id: 1, name: "team1", submitted_hyperlinks: "http://example.com") }
      it "submitted hyperlinks" do
        expect(team1.has_submissions?).to eq(true)
      end

3. The team submits some files. Stub is used to emulate the scenario that the team has submitted a file.

 
      it "returns true" do
        allow(team2).to receive(:submitted_files).and_return([double(:File)])
        expect(team2.has_submissions?).to be true
      end
