ruby-on-rails-4 - Rails，Devise，Rspec:未定义的方法 'sign_in'

Question

我正在尝试使用Devise辅助方法登录和注销在Rails中编写Rspec测试。 sign_in方法不起作用。但是，在对应用程序进行大量更改之前，它可以更早地工作。

我尝试过的事情:

我将测试助手包括在Rspec.configure中。

使用Warden的login_as

清除Rails缓存。

摆脱 capybara ，看看是否引起了

问题

我未在 Controller 规格中明确设置 session (例如，没有有效的 session )

到目前为止，还没有骰子。与登录用户一起测试我的 Controller 时，我需要做些什么？

错误信息:

 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 规格

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

gem 文件

group :development, :test do
    gem 'rspec-rails', '~> 3.0.0.beta'
    gem 'capybara'
    gem 'factory_girl_rails'
    gem 'faker'

    gem 'guard-annotate'

    gem 'guard-livereload', require: false

end

factory / 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

提前致谢。

Answer 1

您最近是否像我一样升级到RSpec 3？这是从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.

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