rspec集成测试与devise throws NoMethodError错误 [英] rspec integration test with devise throws NoMethodError error

问题描述

我的文件'spec / request / news_controller_spec.rb'看起来像： p>

  require'spec_helper'
 
描述NewsControllerdo 
 
 include Devise： ：TestHelpers 
 
描述GET / newsdo 
 
 before（：each）do 
 @ request.env [devise.mapping] = Devise.mappings [：user] 
 @user = Factory.create（：user）
 @ user.confirm！ 
 sign_in @user 
 end 
 
它登录后应显示最新消息屏幕do 
 page.should have_content（新闻）
 end 
 end 
 end 
  

如果我运行测试，我会得到：

 失败：
 
 1）广告系列GET /新闻作品！ 
失败/错误：无法从backtrace找到匹配的行
 NoMethodError：

我按照 https：/ /github.com/plataformatec/devise/wiki/How-To%3a-Controllers-and-Views-tests-with-Rails-3-%28and-rspec%29 和其他类似的问题在这里，但我可以找不到解决方案。

我正在使用以下gemset：

• capybara（1.1.2）


• devise（1.5.3）


• factory_girl_rails（1.6.0）


• （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。

我，通过登录的用户获得我的集成测试。在这种情况下，只有在用户登录时才会显示新闻。

谢谢。

解决方案

我确实有同样的问题，谷歌搜索后，我发现包含 Warden :: Test :: Helpers 直接是一个更多简单的解决方案要求规格，因为它以编程方式登录/注销用户，就像这样：

 ＃spec / support / request_helpers.rb 
 require'spec_helper'
 include Warden :: Test :: Helpers 
 
 module RequestHelpers 
 def create_logged_in_user 
 user = Factory（：user）
登录（用户）
用户
结束
 
 def登录（用户）
 login_as用户，范围：用户
结束
结束
  

简而言之，只包括 Warden :: Test :: Helpers 然后使用 login_as< your_user> 方法，就是这样！

从这里取得的解决方案： http://simple10.com/rspec-capybara-devise-login-tests/

I have a similar error posted here, but all will not fix my problem.

My file 'spec/request/news_controller_spec.rb' looks like:

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

If I run the test I'll get:

I followed instructions on https://github.com/plataformatec/devise/wiki/How-To%3a-Controllers-and-Views-tests-with-Rails-3-%28and-rspec%29 and other similar Questions here, but I can't find a solution.

I'm using following gemset:

• capybara (1.1.2)
• devise (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)

and some other gems.

Can anybody help me, getting my integration tests with a logged in user get running. In this case the news are only displayed, if a user is logged in.

Thanks.

解决方案

I actually had the same exact problem, and after googling a little bit I found that including Warden::Test::Helpers directly was a more concise solution for request specs, since it programmatically signs in/out users just like this:

# 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

In short, just include Warden::Test::Helpers and then use the login_as <your_user> method and that's it!
