如何改進規格

-1

我正在學習Ruby on Rails。而在我的新項目中，我正在使用rspec，shoulda matchers。我只想知道如何改進編寫規格的方式。我還需要在其他模型規格中重複使用「術語」。我怎樣才能做到這一點？如何改進規格

感謝

require 'rails_helper' 

RSpec.describe Portfolio, type: :model do 
    it { should validate_presence_of(:code) } 
    it { should validate_presence_of(:name) } 

    it "has a valid factory" do 
     expect(FactoryGirl.create(:portfolio)).to be_valid
