Rails + Rspec：如何測試環境特定的操作？ 例如“......除非Rails.env.production？”

Question

我正在為支付處理器編寫一個包裝器：

class PaySimpleWrapper 
  attr_reader :transaction

  def initialize(args={})
    @transaction.usesandbox = true unless Rails.env.production?
  ....

我如何測試usessandbox屬性是否僅在非生產環境中設置？

  describe PaySimpleWrapper do
    let(:wrapper) { PaySimpleWrapper.new }

    describe "when in production" do
      before { Rails.stub_chain(:env, :production?) { true } }
      it "uses the live system" do
        expect(wrapper.transaction.usesandbox).to be_false
      end
    end

    describe "when not in production" do
      before { Rails.stub_chain(:env, :production?) { false } }
      it "uses the sandbox" do
        expect(wrapper.transaction.usesandbox).to be_true
      end
    end
  end
