How I'd express the donors choose spec

donors_choose_spec.rb

describe DonorsChoose do
  describe "requesting data" do
    let(:test_title) { "A test project" }

    def mock_request(args)
      request = double(:fetch => %Q/{"proposals": [{"title": "#{test_title}"}]}/)
      DonorsChoose::Request.should_receive(:new).with(args).and_return(request)
    end

    context "via lat & lng" do
      subject do
        described_class.projects_near_me("40.4405556", "-79.9961111")
      end

      before do
        mock_request(:centerLat => "40.4405556", :centerLong => "-79.9961111")
      end

      it { should include_project 'A test project' }
    end

    context "via zip code" do
      subject do
        described_class.projects_by_zip("15232")
      end

      before do
        mock_request(:keyword => "15232")
      end

      it { should include_project 'A test project' }
    end
  end
end
