use autotest on merb with rspec

首先要在确保Merb App的$approot$/autotest/discover.rb文件中加载了”merb”, “rspec”。
discover.rb内容如下
Autotest.add_discovery { "merb" }
Autotest.add_discovery { "rspec" }
安装必要的依赖包
$: sudo apt-get install libgtk2-ruby libnotify-dev
$: wget http://rubyforge.org/frs/download.php/27134/ruby-libnotify-0.3.3.tar.bz2
$: tar jxf ruby-libnotify-0.3.3.tar.bz2
$: cd ruby-libnotify-0.3.3/
$: ruby extconf.rb
$: make && sudo make install

检查libnotify安装是否正确
irb
irb(main):001:0> require 'rnotify'
=> true
irb(main):002:0> quit
autotest会将测试结果信息发送至rontify,我们需要创建一个名为.autotest的脚本并放置在$HOME目录下。这个脚本要正常运行需要launchy Gem和一组icon，现在我们来依次完成。
$: sudo gem install launchy
$: wget http://thelucid.com/files/autotest_images.zip
$: unzip autotest_images.zip
$: mv autotest_images ~/.autotest_images
如果需要对Rspec的测试结果以HTML格式输出就需要对App的spec/spec.opts文件进行编辑，添加如下内容
--format p
--format html:doc/spec/report.html
上面的设置使报告的结果以Html形式保存在了doc/spec目录中，需要手动创建这个目录。
mkdir -p doc/spec
最后就是~/.autotest脚本的内容：
require 'rnotify'
require 'gtk2'
require 'launchy'
