这是David Chelimsky写的一篇RSpec简明指南，原文在这里。
简介
要了解RSpec，我们首先需要了解什么是行为驱动开发（Behaviour Driven Development，简称BDD），BDD是一种融合了可接受性测试驱动计划（Acceptance Test Driven Planning），域驱动设计（Domain Driven Design）以及测试驱动开发（Test Driven Development，简称TDD）的敏捷开发模型。RSpec为BDD开发提供TDD支持。
通常测试Rails项目需要一下gems.
1.cucumber ---最有前途的

2.Capybara ----需要--》 Rack::Test and Selenium
Capybara aims to simplify the process of integration testing Rack applications, such as Rails, Sinatra or Merb. Capybara simulates how a real user would interact with a web application. It is agnostic about the driver running your tests and currently comes with Rack::Test and Selenium support built in. HtmlUnit, WebKit and env.js are supported through external gems.
A complete reference is available at at rubydoc.info.
可以配合cucumber使用。
rails generate cucumber:install --capybara
也可配合Rspec

3.gem install selenium-webdriver ----自动测试框架for IE /Firefox/Chrome/Android/Iphone
WebDriver is a tool for writing automated tests of websites. It aims to mimic the behaviour of a real user,
and as such interacts with the HTML of the application.
