autotest in Gnome"

autotest是个方便的测试工具，ZenTest的组件之一，对Rspec支持很好。

在Peedcode的教学视频中很多时候看到作者用autotest时，测试结果会以桌面系统Notify的形式通知用户，每次看到都觉得好羡慕。其实在Gnome环境下的同学不用羡慕，因为在Gnome下也可以，把你Home目录下的.autotest文件（附件有），加入以下代码，并把附件中的图片文件放到Home下（把dot改为.）。

require 'rnotify' require 'gtk2'

module Autotest::RNotify class Notification attr_accessor :verbose, :image_root, :tray_icon, :notification, :image_pass, :image_pending, :image_fail

def initialize(timeout = 5000, image_root = "#{ENV['HOME']}/.autotest_images" , verbose = false) self.verbose = verbose self.image_root = image_root

puts 'Autotest Hook: loading Notify' if verbose Notify.init('Autotest') || raise('Failed to initialize Notify')

puts 'Autotest Hook: initializing tray icon' if verbose self.tray_icon = Gtk::StatusIcon.new tray_icon.icon_name = 'face-monkey' tray_icon.tooltip = 'RSpec Autotest'

puts 'Autotest Hook: Creating Notifier' if verbose self.notification = Notify::Notification.new('X', nil, nil, tray_icon) notification.timeout = timeout

Thread.new { Gtk.main } sleep 1 tray_icon.embedded? || raise('Failed to set up tray icon')

def notify(icon, tray, title, message) notification.update(title, message, nil) notification.pixbuf_icon = icon tray_icon.tooltip = "Last Result: #{message}" tray_icon.icon_name = tray notification.show end

def passed(title, message) self.image_pass ||= Gdk::Pixbuf.new("#{image_root}/pass.png", 48,48) notify(image_pass, 'face-smile', title, message) end

def pending(title, message) self.image_pending ||= Gdk::Pixbuf.new("#{image_root}/pending.png",48,48) notify(image_pending, 'face-plain', title, message) end

def failed(title, message) self.image_fail ||= Gdk::Pixbuf.new("#{image_root}/fail.png", 48,48) notify(image_fail, 'face-sad', title, message) end

def quit puts 'Autotest Hook: Shutting Down...' if verbose #Notify.uninit Gtk.main_quit end end Autotest.add_hook :initialize do |at| @notify = Notification.new end Autotest.add_hook :ran_command do |at| results = at.results.last puts "the results is #{results}" unless results.nil? output = results[/(\d+)\s+example?,\s*(\d+)\s+failures?(,\s*(\d+)\s+peding)?/] if $~[2].to_i > 0 @notify.failed("Tests Failed", output) elsif $~[4].to_i > 0 @notify.pending("Tests Pending", output) else unless at.tainted @notify.passed("All Tests Passed", output) else @notify.passed("Tests Passed", output) end end end end

Autotest.add_hook :quit do |at| @notify.quit end end

ohoh～～我们来看看效果怎样，在任意一个加入rspec on rails插件的Project下（当然是写了spec的）执行autotest： notify.png

是不是很有趣呢？当然这个依赖于库ruby-gnome2，ruby-libnotify，都是用各自Linux发行班的包管理软件可以轻松得到的，比如我的arch就是，yaourt ruby-gnome2 ruby-libnotify。这个其实也可以用在unit test下，不过需要修改Autotest.add_hook :ran_command中的正则。

Ruby一个可爱的地方就是配置文件也是代码，代码还是代码。autotest的扩展性真好，这也是得益于Ruby的哲学，要修改一个类的行为就打开它，定义它，很优雅。Code is the best firend of Programmer 。
