rspec不能使用设计用户身份验证 [英] rspec not working with devise user authentication

问题描述

我正在尝试使用RSpec来测试我的rails应用程序，它使用devise用户身份验证gem。

  devise（3.4.1）
 rails（4.1.7,4.1.6）
 rspec（3.1.0） 
 rspec-core（3.1.7）
 rspec-expectations（3.1.2）
 rspec-mocks（3.1.3）
 rspec-rails（3.1.0）
 rspec-support（3.1.2）
  

根据devise和rspec的文档，我有一个spec / controller / feed_controller_spec.rb这样：

  require'rails_helper'
 
 RSpec.describe FeedController ，：type => ：$ do 
 
 before（：each）do 
 devise_setup 
 end 
 
它阻止未经身份验证的访问do 
 get：index 
 response.should redirect_to（new_user_session_path）
 end 
 
它允许验证访问do 
 user = User.create！（：foo =>'bar' ...）
 sign_in user 
 get：index 
 expect（response）.to be_success 
 end 
 end 
  / pre> 
 
 
在我的spec / support / controller_macros.rb文件中：
  module ControllerMacros 
 def devise_setup 
 allow（request.env ['warden']）。接收（：authenticate！）。and_throw（：warden，{：scope =>：user}） 
 allow（controller）.to receive（：current_user）.and_return（nil）
 end 
 
 def sign_in（user）
 if user.nil？ 
 allow（request.env ['warden']）。接收（：authenticate！）。and_throw（：warden，{：scope =>：user}）
 allow（controller） （：current_user）.and_return（nil）
 else 
允许（request.env ['warden']）接收（：authenticate！）and_return（user）
 allow（controller） .to receive（：current_user）.and_return（user）
 end 
 end 
 end 
  
最后但并非最不重要的我的spec / spec_helper.rb文件具有以下添加行（在使用rails生成rspec：init命令的文件的顶部）：
  require'devise'
 
 RSpec.configure do | config | 
 config.include Devise :: TestHelpers，：type => ：controller 
 config.extend ControllerMacros，：type => ：控制器
 end 
  
当我在命令行上运行bundle exec rspec时，我收到以下错误：
  /.../ spec / spec_helper.rb：6：在`block in< top（required）> ;'：未初始化的常量ControllerMacros（NameError）
 from /usr/local/lib/ruby/gems/2.1.0/gems/rspec-core-3.1.7/lib/rspec/core.rb:81:in 'configure'
 from /home/vagrant/code/pulse/spec/spec_helper.rb:4:in`< top（required）>'
  
当我从spec_helper.rb文件中注释出ControlMacros行，它给出以下内容：
  1）FeedController阻止未经身份验证的访问
失败/错误：devise_setup 
 NameError：
未定义局部变量或方法`devise_setup'for＃< RSpec :: ExampleGroups :: FeedController：0xba5d20f4> 
＃./spec/controllers/feed_controller_spec.rb:9:in`（$）$（$）
 
 2）FeedController允许身份验证访问
失败/错误：devise_setup 
 NameError：
未定义局部变量或方法`devise_setup'for＃< RSpec :: ExampleGroups :: FeedController：0xba5c76a4> 
＃./spec/controllers/feed_controller_spec.rb:9:in'block（2 levels）in< top（required）>'
  
 
 
解决方案
似乎需要 require'support / controller_macros'。  spec / support 子目录中的文件是自动加载但不是必需的。
 
I am attempting to use RSpec to test my rails application which uses devise user authentication gem.

Here are a list of relevant gems already bundled:
devise (3.4.1)
rails (4.1.7, 4.1.6)
rspec (3.1.0)
rspec-core (3.1.7)
rspec-expectations (3.1.2)
rspec-mocks (3.1.3)
rspec-rails (3.1.0)
rspec-support (3.1.2)
As per the documentation for devise and rspec I have a spec/controller/feed_controller_spec.rb like this:
require 'rails_helper'

RSpec.describe FeedController, :type => :controller do

  before(:each) do
    devise_setup
  end

  it "blocks unauthenticated access" do
    get :index
    response.should redirect_to(new_user_session_path)
  end

  it "allows authenticated access" do
    user = User.create!(:foo => 'bar', ...)
    sign_in user
    get :index
    expect(response).to be_success
  end
end
And in my spec/support/controller_macros.rb file:
module ControllerMacros
  def devise_setup
      allow(request.env['warden']).to receive(:authenticate!).and_throw(:warden, {:scope => :user})
      allow(controller).to receive(:current_user).and_return(nil)
  end

  def sign_in(user)
    if user.nil?
      allow(request.env['warden']).to receive(:authenticate!).and_throw(:warden, {:scope => :user})
      allow(controller).to receive(:current_user).and_return(nil)
    else
      allow(request.env['warden']).to receive(:authenticate!).and_return(user)
      allow(controller).to receive(:current_user).and_return(user)
    end
  end
end
And last but not least my spec/spec_helper.rb file has the following added lines (at the top of the file that was created using rails generate rspec:init command):
require 'devise'

RSpec.configure do |config|
  config.include Devise::TestHelpers, :type => :controller
  config.extend ControllerMacros, :type => :controller
end
When I run bundle exec rspec on the command line I receive the following error:
/.../spec/spec_helper.rb:6:in `block in <top (required)>': uninitialized constant ControllerMacros (NameError)
    from /usr/local/lib/ruby/gems/2.1.0/gems/rspec-core-3.1.7/lib/rspec/core.rb:81:in `configure'
    from /home/vagrant/code/pulse/spec/spec_helper.rb:4:in `<top (required)>'
When I comment out the ControlMacros line from the spec_helper.rb file it gives the following:
1) FeedController blocks unauthenticated access
   Failure/Error: devise_setup
   NameError:
     undefined local variable or method `devise_setup' for #<RSpec::ExampleGroups::FeedController:0xba5d20f4>
   # ./spec/controllers/feed_controller_spec.rb:9:in `block (2 levels) in <top (required)>'

2) FeedController allows authenticated access
   Failure/Error: devise_setup
   NameError:
     undefined local variable or method `devise_setup' for #<RSpec::ExampleGroups::FeedController:0xba5c76a4>
   # ./spec/controllers/feed_controller_spec.rb:9:in `block (2 levels) in <top (required)>'

解决方案
Seems like you need to require 'support/controller_macros'. Files in the spec/support subdirectory are auto-loaded but not required.
