RSpec에 테스트 모델 : 일부 속성에 거짓 : 거짓 제약

Question

나는 시험 (RSpec에) 널 (null)와 모델과 혼란 스러워요

그 속성 = 전무 중 하나를 새 인스턴스로 새로운 인스턴스를 생성. 유효한? true를 반환하지만 저장하려고하면 ActiveRecord :: NotNullViolation에 오류 메시지가 반환됩니다. '모델 유효성 검사'를 통과했지만 '데이터베이스 유효성 검사'에서 실패하는 것으로 알고 있습니다. 그런 다음 내 모델을 테스트하는 올바른 방법은 무엇입니까?

RSpec.describe BusinessSetting, type: :model do 
    # before :each do 
    # @business_setting = FactoryGirl.create(:business_setting) 
    # end 

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

    it "is invalid without a business_id" do 
    expect(FactoryGirl.create(:business_setting, business_id: 
nil)).not_to be_valid 
    end 

    it "is invalid without a bot_token" do 
    expect(FactoryGirl.build(:business_setting, bot_token: nil)).to 
raise_error 
    end 
end

Answer 1

expect to raise_error이

expect{FactoryGirl.create(:business_setting, business_id: nil)}.to raise_error
