ruby-on-rails - 使用 Rspec 测试页面重定向后的通知

Question

登录用户尝试访问新操作和创建操作后，尝试在页面重定向后测试通知。

规范失败:

失败:

1) Authentication authorization as signed in master submitting a GET request to the Masters#new action 
     Failure/Error: it { should have_content("You cannot complete this request when signed in.") }
     Capybara::ElementNotFound:
       Unable to find xpath "/html"
     # ./spec/requests/authentication_pages_spec.rb:126:in `block (5 levels) in <top (required)>'

  2) Authentication authorization as signed in master submitting a POST request to the Masters#create action 
     Failure/Error: it { should have_content("You cannot complete this request when signed in.") }
     Capybara::ElementNotFound:
       Unable to find xpath "/html"
     # ./spec/requests/authentication_pages_spec.rb:132:in `block (5 levels) in <top (required)>'

过滤前:

before_action :already_signed_in, only: [:new, :create]

def already_signed_in
    redirect_to root_url, notice: "You cannot complete this request when signed in." if signed_in?
end

授权规范:

context "as signed in master" do 
  let(:master) { FactoryGirl.create(:master) }
  before { sign_in master, no_capybara: true }
  subject { page }

  context "submitting a GET request to the Masters#new action" do 
    before { get new_master_path }
    specify { expect(response).to redirect_to(root_url) }
    it { should have_content("You cannot complete this request when signed in.") }
  end

  context "submitting a POST request to the Masters#create action" do 
    before { post masters_path }
    specify { expect(response).to redirect_to(root_url) }
    it { should have_content("You cannot complete this request when signed in.") }
  end
end

Answer 1

嗯，是啊!响应没有任何内容，因为它是重定向!

所以你可以询问flash对象是否有消息。

如果您确实想知道它是否显示在下一页上，您需要编写集成测试，因为它实际上会遵循浏览器中的重定向并检查后续页面中的消息。
