Mumble your tests!

I’ve been working on a rails project, and in some screen cast, I saw autotest+growl and fell in love. I googled a bit for a Linux version of growl, and I found Mumbles. There was no built in autotest support, so I hacked around, extended the Mumbles dbus interface just a little, and then made a simple autotest hook that uses Mumbles.

Until the author commits my patch to his repository, you can get my patched version as a tarball here: Mumbles patched (its a bziped tarball, not a jpeg file - wordpress limitations, so right-click and save as)

And here’s the autotest plugin:

require 'dbus'

def send_message(title, message, icon)
  begin
    bus = DBus::SessionBus.instance
    mumbles_service = bus.service("org.mumblesproject.Mumbles&quot 
    mumbles = mumbles_service.object("/org/mumblesproject/Mumbles&quot 
    mumbles.introspect
    mumbles_iface = mumbles["org.mumblesproject.Mumbles"]
    sig = mumbles_iface.signals["Notify"]
    bus.emit(mumbles_service, mumbles, mumbles_iface, sig, title, message, icon)
  rescue Exception => e
  end
end

Autotest.add_hook :ran_command do |at|
   begin
     output = at.results.last.slice(/(\d+) examples?, (\d+) failures?(, \d+ pending)?/)
     if output =~ /.*[1-9] failure.*/ then
       send_message("FAIL", "#{output}", "fail.png&quot 
     else
       send_message("PASS", "#{output}", "pass.png&quot 
     end
  rescue Exception => e
  end
end

You’ll need the ruby-dbus library which you can get here

*Update:* surrounded the hook with begin rescue. Without this, autotest would crash if I had a syntax error in my spec, because at.result.last would be nil
