FactoryGirl源代码
https://github.com/thoughtbot/factory_girl_rails
factory_girl
factory_girl is a fixtures replacement with a straightforward definition syntax, support for multiple build strategies (saved instances, unsaved instances, attribute hashes, and stubbed objects), and support for multiple factories for the same class (user,admin_user, and so on), including factory inheritance.
Rails
factory_girl_rails provides Rails integration for factory_girl. All Rails-specific features are only compatible with Rails 3.
Currently, automatic factory definition loading is the only Rails-specific feature.

Gem:
gem install factory_girl_rails Configuration
Add factory_girl_rails to your Gemfile:
gem 'factory_girl_rails' Generators for factories will automatically substitute fixture (and maybe any other fixture_replacement you set). If you want disable this feature, add the following to your application.rb file:
config.generators do |g| g.factory_girl false end Default factories directory is test/factories, or spec/factories if test_framework generator is set to :rspec; change this behavior with:
config.generators do |g| g.factory_girl dir: 'custom/dir/for/factories' end If you use factory_girl for fixture replacement, ensure that factory_girl_rails is available in the development group. If it's not, Rails will generate standard yml files instead of factory files.
factory_girl takes an option suffix: 'some_suffix' to generate factories as "modelname_some_suffix.rb"
例子：
修改Gemfile，添加factory-girl-rails
group :test do
gem 'capybara','1.1.2'
gem 'factory_girl_rails','4.1.0'
end
执行bundle install进行安装
新建spec/factories.rb，添加如下内容
FactoryGirl.define do
factory :user do
name "Michael Roshen"
email "[email protected]"
password "foobar"
password_confirmation "foobar"
end
end
let(:user) { FactoryGirl.create(:user) } 定义user
spec/request/user_pages_spec.rb
require 'spec_helper'
describe "UserPages" do
subject { page }
describe "signup page" do
before { visit signup_path }
it { should have_selector('h1', text: "Sign Up") }
it { should have_selector("title", text: full_title("Sign Up"))}
end
describe "profile page" do
let(:user) { FactoryGirl.create(:user)}
before { visit user_path(user)}
it { should have_selector('h1', text: user.name)}
it { should have_selector('title', text: user.name)}
end
end
Rspec默认使用fixture，如果使用factorygril，则需要将默认配置注释掉
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
# Remove this line if you're not using ActiveRecord or ActiveRecord fixtures
config.fixture_path = "#{::Rails.root}/spec/fixtures"
# If you're not using ActiveRecord, or you'd prefer not to run each of your
# examples within a transaction, remove the following line or assign false
# instead of true.
config.use_transactional_fixtures = true
# If true, the base class of anonymous controllers will be inferred
# automatically. This will be the default behavior in future versions of
# rspec-rails.
config.infer_base_class_for_anonymous_controllers = false
# 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
