Question

这是我编写的规范的代码。我试图为一个数组（付款）做一个，但是当我尝试在它上面添加let变量时，它告诉我变量或方法不存在。所以我假设变量没有被调用。

任何人都可以看看我应该如何重新规范我的规范，以便我可以做这样的事情：

payments.each do |p|
  it "updates the payment record of #{p.id} with a status of #{p.status}" do
    payments.each do |p|
      payment = Payment.find_by_id(p.id)
      payment_status = payment.status
      payment_status = p.status
      subject
      expect(Payment.find_by_id(p.id).status).to_not eq(payment_status)
    end
  end
end

原始规格代码：

  describe "PATCH #submit" do
    subject { patch :pay, :payment => [payments] }
    context "when the submission is valid" do
      let(:payments) { [] }
      let(:admin) { FactoryGirl.create(:admin) }
      let(:member) { FactoryGirl.create(:member) }
      let(:user) { FactoryGirl.create(:user }

      before :each do
        rand(2..4).times { payments << FactoryGirl.create(:payment, :payor => member, :merchant => user) }
        sign_in admin
      end

      it "updates the status of the payment" do
        p = payments.sample #get a random payment submitted
        payment = Payment.find_by_id(p.id)
        payment_status = payment.status
        subject
        p.reload
        expect(p.status).to_not eq(payment_status)
      end

      it "updates the record in the array" do
        payments.each do |p|
          payment = Payment.find_by_id(p.id)
          payment_status = payment.status
          payment_status = p.status
          subject
          expect(Payment.find_by_id(p.id).status).to_not eq(payment_status)
        end
     end
    end
  end

您不能在规范之外使用let定义的变量。如果你真的想让它可用，请在你的规范上定义一个方法并像这样使用它。

This question seems similar, with a similar response

RSpec将变量或（let变量）传递给它
