Rubyonrails RailsRspec 在控制器中测试重定向

因此，我目前正在为现有控制器中的一个控制器编写一个测试，这个控制器以前没有.我想测试的是一个重定向，当有人不允许编辑某个内容，而有人允许编辑它时，就会发生重定向.

正在编辑的控制器操作

def edit
  if !@scorecard.reviewed? || admin?
    @company = @scorecard.company
    @custom_css_include = "confirmation_page"
  else
    redirect_to :back
  end
end

因此，如果一个记分卡已经过审核，那么只有管理员可以编辑该分数.

# scorecards
resources :scorecards do
  member do
    get 'report'
  end
  resources :inaccuracy_reports, :only => [:new, :create]
end

最后是测试

  require 'spec_helper'

  describe ScorecardsController do

    describe "GET edit" do
      before(:each) do
        @agency = Factory(:agency)
        @va = Factory(:va_user, :agency => @agency)
        @admin = Factory(:admin)
        @company = Factory(:company)
        @scorecard = Factory(:scorecard, :level => 1, :company => @company, :agency => @agency, :reviewed => true)
        request.env["HTTP_REFERER"] = "/scorecard"
      end

      context "as a admin" do
        before(:each) do
          controller.stub(:current_user).and_return @admin
        end

        it "allows you to edit a reviewed scorecard" do
          get 'edit', :id => @scorecard.id
          response.status.should be(200)
        end
      end

      context "as a va_user" do
        before(:each) do
        controller.stub(:current_user).and_return @va
      end

      it "does not allow you to edit a reviewed scorecard" do
        get 'edit', :id => @scorecard.id
        response.should redirect_to :back
      end
    end
  end
end

因此，va在试图编辑已审核的分数时将被重定向回，而管理员不会.

但在rspec上运行时，我发现

ScorecardsController
  GET edit
    as a admin
      allows you to edit a reviewed scorecard
    as a va_user
      does not allow you to edit a reviewed scorecard (FAILED - 1)

Failures:

  1) ScorecardsController GET edit as a va_user does not allow you to edit a reviewed scorecard
     Failure/Error: response.should redirect_to :back
   Expected response to be a redirect to </scorecard> but was a redirect to <http://test.host/>
     # ./spec/controllers/scorecards_controller_spec.rb:33:in `block (4 levels) in <top (required)>'

Finished in 0.48517 seconds
2 examples, 1 failure

所以我不知道它是否有效，因为我把request.env["HTTP_REFERER"] = "/scorecard"设置为应该是:back的位置.或者，我是不是错过了这个 idea ？看httpstatus个答案，我可以使用300个答案，但我不知道从哪里开始？

任何帮助都会很棒

编辑

我可以这样做来测试

...
response.status.should be(302)

但我是从这question条中得到这个 idea 的，它听起来可能很强大，因为它指定了重定向到的url.

有人做过这样的测试吗？
