rspec&设计测试助手 [英] rspec & devise test helpers

问题描述

根据这从devise wiki我应该能够在我的控制器测试中使用一个login_user帮助程序。因此，我在规格目录中有以下内容：

 ＃spec_helper.rb 
 ... 
目录[Rails.root.join（spec / support / ** / *。rb）]。 require f} 
 
 RSpec.configure do | config | 
 config.include Devise :: TestHelpers，：type => ：controller 
 config.extend ControllerMacros，：type => ：控制器
 ... 
  

和

 ＃support / controller_macros.rb 
 module ControllerMacros 
 def login_user 
 before（：each）do 
 @ request.env [ devise.mapping] = Devise.mappingings [：user] 
 @user = Factory.create（：user）
 sign_in @user 
 end 
 end 
 end 
  

但是调用助手不起作用：

$ $ $ $ $ $ $ $ $需要'spec_helper'
描述GET / guides / editdo
login_user
end

有人可以指向我错在哪里。测试套件从此开始工作。我得到一个未定义的局部变量或方法消息，所以我猜是没有包含该模块。

rspec 2.6.0
设计1.3.4

解决方案

我想象这种方法有几个问题。首先是使用请求规范而不是控制器规范，所以 login_user 方法不能通过 config.extend ControllerMacros，：type = > ：控制器。第二，即使您能够包含该方法，也很有可能无法正常工作，因为Devise测试帮助者专门为控制器/视图测试而编写，而不是集成测试。

看看David Chelimsky的答案到这个SO问题，这可能是有帮助的。

According to this from the devise wiki I should be able to use a login_user helper method in my controller tests. Accordingly I have the following within the spec directory:

#spec_helper.rb
...
Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}

RSpec.configure do |config|
  config.include Devise::TestHelpers, :type => :controller
  config.extend ControllerMacros, :type => :controller
...

and

#support/controller_macros.rb
module ControllerMacros    
  def login_user
    before(:each) do
      @request.env["devise.mapping"] = Devise.mappings[:user]
      @user = Factory.create(:user)
      sign_in @user
    end
  end
end

however calling the helper doesn't work:

#requests/some_spec.rb
require 'spec_helper'
describe "GET /guides/edit" do
  login_user     
end

Can someone point toward where I'm going wrong. The test suite works about from this. I get a undefined local variable or method message so I guess the module isn't being included.

解决方案

I imagine there are a couple of problems with this approach. First is that you're using request specs, not controller specs, so the login_user method is not made available by config.extend ControllerMacros, :type => :controller. Second, even if you are able to include the method it most likely won't work anyway, since the Devise test helpers are specifically written for controller/view tests, not integration tests.

Take a look at David Chelimsky's answer to this SO question, which may be of help.
