Rails，Devise，Rspec：未定义的方法'sign_in' [英] Rails, Devise, Rspec: Undefined method 'sign_in'

问题描述

我正在尝试用Rails编写Rspec测试，使用Devise帮助方法登录和注销。 sign_in方法不起作用但是，在应用程序发生了一些变化之前，它已经工作得更早了。

我尝试过的东西：

• 我在Rspec.configure中包含测试助手。


• 使用Warden的login_as


• 清除Rails缓存。


• 摆脱Capybara看看是否导致问题


• 我没有在我的控制器规范中明确地设置会话（例如没有valid_session）

到目前为止，没有骰子。使用登录用户测试我的控制器需要做些什么？

错误消息：

  OrderItemsController GET #index渲染：索引视图
失败/错误：sign_in：admin 
 NoMethodError：
未定义的方法`sign_in'用于＃< RSpec :: ExampleGroups :: OrderItemsController_2 :: GETIndex：0x00000102c002d0>

解决方案

你最近像我一样升级到RSpec 3吗？这是来自 RSpec 3文档 ：

自动添加元数据
3.0.0之前的RSpec版本会自动将元数据添加到基于
的基础上，文件系统。这对于新用户而言是混乱的，而对于一些老用户来说，这不是
。

在RSpec 3中，必须明确启用此行为：

 ＃spec / rails_helper.rb 
 RSpec.configure do | config | 
 config.infer_spec_type_from_file_location！ 
 end 
  

由于这个假设行为在教程中非常流行，所以默认的
由rails生成的配置生成rspec：install启用此功能。

如果您遵循上述列举的规范目录结构，并且
配置为infer_spec_type_from_file_location !, RSpec将自动
包含每个类型的正确的支持功能。

添加该配置代码片段后，我不再需要指定规范类型（例如 type：：controller ）。

I am trying to write Rspec tests in Rails, using Devise helper methods for signing in and out. The sign_in method is not working. However, it had been working earlier, before a slew of changes to the app.

Things I have tried:

• I am including the test helpers in Rspec.configure.
• Using Warden's login_as
• Clearing the Rails cache.
• Getting rid of Capybara to see if that were causing the issue
• I am not setting the session explicitly in my controller specs (e.g. no valid_session)

So far, no dice. What do I need to do differently to test my controllers with a signed-in user?

Error message:

 OrderItemsController GET #index renders the :index view
 Failure/Error: sign_in :admin
 NoMethodError:
      undefined method `sign_in' for #  <RSpec::ExampleGroups::OrderItemsController_2::GETIndex:0x00000102c002d0>
 # ./spec/controllers/order_items_controller_spec.rb:6:in `block (2 levels) in <top (required)>'

Controller Spec

require 'spec_helper'

describe OrderItemsController do
    before (:each) do
        admin = create(:admin)
        sign_in :admin
    end

    describe "GET #index" do
        it "renders the :index view" do
            get :index
            expect( response ).to render_template :index
        end
    end
end

spec_helper.rb

require 'rspec/rails'
require 'capybara/rspec'

RSpec.configure do |config|

  config.include ApplicationHelper
  config.include ControllersHelper
  config.include UsersHelper
  config.include Devise::TestHelpers, type: :controller
  config.include FactoryGirl::Syntax::Methods

end

Gemfile

end

factories/user.rb

FactoryGirl.define do

    factory :user do
        first                   { Faker::Name.first_name }
        last                    { Faker::Name.last_name }
        email                   { Faker::Internet.email }
        admin                   false
        password                "secrets1"
        password_confirmation   "secrets1"
        confirmed_at            Date.today

        factory :admin do
            admin               true
        end
    end
end

Thanks in advance.

解决方案

Did you recently upgrade to RSpec 3 like I did? This is from the RSpec 3 documentation:

Automatically Adding Metadata RSpec versions before 3.0.0 automatically added metadata to specs based on their location on the filesystem. This was both confusing to new users and not desirable for some veteran users.

In RSpec 3, this behavior must be explicitly enabled:

​# spec/rails_helper.rb
RSpec.configure do |config|
    config.infer_spec_type_from_file_location!
end

Since this assumed behavior is so prevalent in tutorials, the default configuration generated by rails generate rspec:install enables this.

If you follow the above listed canonical directory structure and have configured infer_spec_type_from_file_location!, RSpec will automatically include the correct support functions for each type.

After I add that configuration snippet, I no longer have to specify the spec type (e.g. type: :controller).
