Rails + Rspec：如何测试环境特定的操作？例如＆＃34; ...除非Rails.env.production？＆＃34;

Question

我正在为付款处理器编写包装器：

class PaySimpleWrapper 
  attr_reader :transaction

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

我如何测试usessandbox属性是否仅在非生产环境中设置？

  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
