使用Devise进行Rspec控制器测试无法测试重定向

Question

我只是想测试一个:user未在签订，将会被重定向到new_user_session_path，当他们试图访问的东西，他们不能。

当我打电话时：

describe "GET new" do 
    it 'expects redirect unless admin' do
        get :new
        expect(response).to redirect_to(new_user_session_path)
    end
end

我收到以下错误：

1) MealsController GET new expects redirect unless admin
     Failure/Error: redirect_to new_user_session_path, alert: "You must be signed in to access this page."

     NameError:
       undefined local variable or method `new_user_session_path' for #<MealsController:0x007fa066d5d230>
       Did you mean?  new_user_invitation_path

为什么会这样？

编辑：这是我的用户路线：

new_user_session GET    /users/sign_in(.:format)                                                                 sessions#new
