以下是一些关于测试的基本gem的引入和初始化，方便以后copy&past。
1. 引入gem
# rspec-rails is a testing framework for Rails 3.x and 4.x.
# https://github.com/rspec/rspec-rails
gem 'rspec-rails', '~> 3.2.1'

# http://matchers.shoulda.io
gem 'shoulda-matchers', :require => false
# A library for setting up Ruby objects as test data
