Question

我在这里发布了类似的错误，但都无法解决我的问题。

我的文件'spec / request / news_controller_spec.rb'如下：

require 'spec_helper'

describe "NewsController" do

  include Devise::TestHelpers

  describe "GET /news" do

    before(:each) do
      @request.env["devise.mapping"] = Devise.mappings[:user]
      @user = Factory.create(:user)
      @user.confirm!
      sign_in @user
    end

    it "after login should show the latest news an screen" do
      page.should have_content("News")
    end
  end
end

如果我参加测试，我会得到：

我在此处遵循了https://github.com/plataformatec/devise/wiki/How-To%3a-Controllers-and-Views-tests-with-Rails-3-%28and-rspec%29和其他类似问题的说明，但我找不到解决方案。

我正在使用以下gemset：

capybara（1.1.2）
设计（1.5.3）
factory_girl_rails（1.6.0）
rails（3.2.0,3.1.1）
rspec（2.8.0）
rspec-core（2.8.0）
rspec-expectations（2.8.0）
rspec-mocks（2.8.0）
rspec-rails（2.8.1）

和其他一些宝石。

任何人都可以帮助我，让登录用户的集成测试得到运行。在这种情况下，只有在用户登录时才会显示新闻。

感谢。

我实际上遇到了同样的问题，经过谷歌搜索后我发现直接包含Warden::Test::Helpers是一个更简洁的请求规范解决方案，因为它以编程方式登录/注销用户：

# spec/support/request_helpers.rb
require 'spec_helper'
include Warden::Test::Helpers

module RequestHelpers
  def create_logged_in_user
    user = Factory(:user)
    login(user)
    user
  end

  def login(user)
    login_as user, scope: :user
  end
end

简而言之，只需添加Warden::Test::Helpers，然后使用login_as <your_user>方法就可以了！
