Ubuntu11.10+ruby on rails 3+rspec+autotest 配备

Ubuntu11.10+ruby on rails 3+rspec+autotest 配置
step1:    创建新的项目，不包含默认测试文件(-T)
    $ rails new sampleapp -T

step2:
    $ cd sampleapp

step3:
    修改Gemfile
    添加

    gem 'therubyracer'
    group :development do
    gem 'rspec-rails'
    end
    group :test do
    gem 'rspec'
    gem 'webrat'
    end

step4:
    $ bundle install

step5:    安装rspec
    $ rails generate rspec:install

step6:    新建几个页面，【并删掉部分测试(可略过)】
    $ rails generate controller Pages home contact
    $ rm -rf spec/views
    $ rm -rf spec/helpers

step7: 安装autotest（http://automate-everything.com/2009/08/gnome-and-autospec-notifications/#comments)
    
    $sudo gem install ZenTest
    【#可能在安装的时候提示gem版本太低,需要~>1.8，需要升级，以下给出升级方法（直接gem update --system是不行的）：
    #$sudo gem install rubygems-update -v 1.8.24（我安装时的最新版本）
    #$sudo update_rubygems
    #$sudo gem update --system
    #】
    $sudo gem install redgreen
    $sudo apt-get install libnotify-bin
step8:
    新建文件~/.autotest，内容如下
 

   #!/bin/ruby
    require 'redgreen' #若为ubuntu11.*需要去掉此行
    require 'autotest/timestamp'
    module Autotest::GnomeNotify
        def self.notify title, msg, img
            system "notify-send '#{title}' '#{msg}' -i #{img} -t 3000"
        end
        Autotest.add_hook :ran_command do |at|
            image_root = "~/.autotest_images"
            results = [at.results].flatten.join("\n")
            results.gsub!(/\\e\[\d+m/,'')
            output = results.slice(/(\d+)\sexamples?,\s(\d+)\sfailures?(,\s(\d+)\spending?|)/)
            full_sentence, green, failures, garbage, pending = $~.to_a.map(&:to_i)
            if output
                if failures > 0
                    notify "FAIL", "#{output}", "#{image_root}/fail.png"
                elsif pending > 0
                    notify "Pending", "#{output}", "#{image_root}/pending.png"
                else
                    notify "Pass", "#{output}", "#{image_root}/pass.png"
                end
            end
        end
    end

step9:
    下载autotest_images.zip，将.autotest_images放到放到~/下，即~/.autotest_images/
    下载链接：http://automate-everything.com/wp-content/uploads/2009/08/autotest_images.zip

step10:享受成果。
$cd sampleapp  #若已在此目录，略过
$autotest
