Devise和Rspec-测试未经身份验证的用户的重定向时，控制器测试中的错误

Question

I'm trying to write a test that makes sure unauthenticated useres are not able to access a certain page. Here is my spec

   it "redirects to the sign in page for unauthenticated users" do
      bob = Fabricate(:user)
      sign_out bob
      carolina_skiff = Fabricate(:boat_brand)
      get :edit, id: carolina_skiff.id
      expect(response).to redirect_to new_user_session_path
    end

When I run this I get this error.

Failure/Error: get :edit, id: carolina_skiff.id
     ArgumentError:
       uncaught throw :warden

It seems like I'm not able to log out a user. I have another spec where I'm signing in a user and that one works fine.

   it "sets the @boat_brand" do
      bob = Fabricate(:user)
      sign_in bob
      carolina_skiff = Fabricate(:boat_brand)
      get :edit, id: carolina_skiff.id
      expect(assigns(:boat_brand)).to eq(carolina_skiff)
    end

Any help would be greatly appreciated.

I don't know if it will help, but I came across similar problem when trying to do functional tests of devise redirection after log in. These are important points:

1. Test exactly Devise::SessionsController (not eg. UsersController) or write test Devise::SessionsController
2. Force correct mapping as described in docs: https://github.com/plataformatec/devise/wiki/How-To:-Test-controllers-with-Rails-3-and-4-(and-RSpec)
3. include Devise::TestHelpers

Sample test with redirection can look like this:

require "test_helper"

describe 'Devise::SessionsControllerTest' do
  # If you want different name in describe block write:
  # tests Devise::SessionsController

  include Devise::TestHelpers

  test "should redirect to page_x after logged in" do
    @request.env["devise.mapping"] = Devise.mappings[:user]
    user = users :user
    sign_in user
    get :new
    assert_redirected_to orders_path
  end
end

Where :user is just regular valid devise user, and orders_path is expected redirect path after log in. This is not exact log in test but rather test of the redirection from login page for logged in user (to be precise).
