Rails 4与rspec和factory_girl_rails安装引擎

Question

我正在用mongoid odm构建一个轨道4安装的应用程序。一切正常，但rspec测试无法正常工作。当我运行bundle exec rspec时出现错误，说：

厂没有登记：cafcaf_user

我的用户模型：

module Cafcaf 
    class User 
    include Mongoid::Document 
    field :username, type: String 
    field :email, type: String 
    field :full_name, type: String 
    field :last_name, type: String 
    end 
end 

我spec_helper.rb

# This file is copied to spec/ when you run 'rails generate rspec:install' 
ENV["RAILS_ENV"] ||= 'test' 
require File.expand_path("../../spec/test_app/config/environment.rb", __FILE__) 
require 'rspec/rails' 

# Requires supporting ruby files with custom matchers and macros, etc, in 
# spec/support/ and its subdirectories. Files matching `spec/**/*_spec.rb` are 
# run as spec files by default. This means that files in spec/support that end 
# in _spec.rb will both be required and run as specs, causing the specs to be 
# run twice. It is recommended that you do not name files matching this glob to 
# end with _spec.rb. You can configure this pattern with with the --pattern 
# option on the command line or in ~/.rspec, .rspec or `.rspec-local`. 
Dir[Rails.root.join("spec/support/**/*.rb")].each { |f| require f } 

# Checks for pending migrations before tests are run. 
# If you are not using ActiveRecord, you can remove this line. 
ActiveRecord::Migration.check_pending! if defined?(ActiveRecord::Migration) 

RSpec.configure do |config| 
    # ## Mock Framework 
    # 
    # If you prefer to use mocha, flexmock or RR, uncomment the appropriate line: 
    # 
    # config.mock_with :mocha 
    # config.mock_with :flexmock 
    # config.mock_with :rr 

    # Run specs in random order to surface order dependencies. If you find an 
    # order dependency and want to debug it, you can fix the order by providing 
    # the seed, which is printed after each run. 
    #  --seed 1234 
    config.order = "random" 
end 

我user_spec.rb

require 'spec_helper' 
module Cafcaf 
    describe User do 

    it "has a valid factory" do 
     FactoryGirl.create(:cafcaf_user).should be_valid 
    end 
    it "is invalid without a username" 
    it "is invalid without an email" 
    end 
end 

我factories.rb

FactoryGirl.define do 
    factory :cafcaf_user, :class => 'User' do 
    username "MyString" 
    email "MyString" 
    full_name "" 
    last_name "MyString" 
    end 
end 

我的lib/cafcaf/engine.rb

module Cafcaf 
    class Engine < ::Rails::Engine 
    isolate_namespace Cafcaf 
    config.generators do |g| 
     g.test_framework :rspec 
     g.fixture_replacement :factory_girl, :dir => 'spec/factories' 
    end 
    end 
end 

我的Gemfile

source "https://rubygems.org" 


gem 'rails', "~> 4.0.4" 
gem 'mongoid', github: 'mongoid/mongoid', tag: 'v4.0.0.beta1' 

group :development, :test do 
    gem 'rspec-rails', '~> 3.0.0.beta2' 
    gem 'database_cleaner', '~> 1.2.0' 
    gem 'factory_girl_rails', '~> 4.4.1' 
end 

我gemspec

$:.push File.expand_path("../lib", __FILE__) 
require "cafcaf/version" 

# Describe your gem and declare its dependencies: 
Gem::Specification.new do |s| 
    s.name  = "cafcaf" 
    s.version  = Cafcaf::VERSION 
    s.authors  = ["Your name"] 
    s.email  = ["bla@bla.com"] 
    s.homepage = "http://ir.io" 
    s.summary  = "Summary of Cafcaf." 
    s.description = " Description of Cafcaf." 

    s.files = Dir["{app,config,db,lib}/**/*", "MIT-LICENSE", "Rakefile", "README.rdoc"] 

    s.add_dependency "rails", "~> 4.0.4" 
end 

正是我不知道要继续。如何在安装的rails引擎应用程序中使用rspec和factory_girs gem？我做了大量的测试，但没有找到解决方案。

Answer 1

我发现通过添加以下代码解决spec_helper.rb

ENGINE_RAILS_ROOT=File.join(File.dirname(__FILE__), '../') 
Dir[File.join(ENGINE_RAILS_ROOT, "spec/factories/**/*.rb")].each {|f| require f } 

现在，它就像一个魅力。
