Question

我正在编写一个控制器规范来验证这个私有方法，但我得到了错误Module::DelegationError: ActionController::RackDelegation，但我很失落，因为如何解决这个问题。我找到的最好的例子是http://owowthathurts.blogspot.com/2013/08/rspec-response-delegation-error-fix.html。

如何通过unverified规范？我想确保401被退回。

方式

def validate_api_request
  return four_oh_one unless api_request_verified?(request)
end

当前规范

describe Api::ApiController, type: :controller do
  describe '#validate_api_request' do
    it 'verified' do
      allow_any_instance_of(described_class).to receive(:api_request_verified?).and_return(true)
      expect(subject.send(:validate_api_request)).to be_nil
    end

    it 'unverified' do
      allow_any_instance_of(described_class).to receive(:api_request_verified?).and_return(false)
      allow(controller).to receive(:redirect_to)
      binding.pry
    end
  end
end

我正在使用Rails 4。

如果有人正在处理编写控制器规范的类似问题，请按以下两个指南解决此问题：http://codegur.com/22603728/test-user-authentication-with-rspec和https://gayleforce.wordpress.com/2012/12/01/testing-rails-before_filter-method/。

describe Api::ApiController, type: :controller do
  describe '#validate_api_request' do
    controller(Api::ApiController) do
      before_filter :validate_api_request
      def fake
        render text:  'TESTME'
      end
    end

    before do
      routes.draw { get 'fake', to: 'api/api#fake' }
    end

    it 'verified' do
      allow_any_instance_of(described_class).to receive(:api_request_verified?).and_return(true)
      expect(subject.send(:validate_api_request)).to be_nil
    end

    it 'unverified' do
      allow_any_instance_of(described_class).to receive(:api_request_verified?).and_return(false)
      get 'fake'
      expect(response.status).to be(401)
    end
  end
end

在Rspec中的API控制器测试模块中获取委派错误
