Autotest, RSpec and Growl on OS X ☆

I’ve just been getting autotest (part of the ZenTest suite) to work. It’s a really good framework for just getting your tests to run automatically in the background.

Following the instructions in one of the fantastic PeepCode screencasts I got the notifications from autotest to get piped though to Growl

In the PeepCode Episode there’s a link to to Wincent Colaiuta’s knowledge base on how to do this. However, it would seem that the formatting of the RSpec output has changed since this ~/.autotest file was written. “Not implemented” strings have changed to “Pending”

49 examples, 0 failures, 1 pending

I’ve rewritten the file and you can find it below. I also extended it slightly as I wanted to see when tests were pending. Now if there are no failures, but there are pending descriptions they will be flagged up with a different icon so you know theres some tests to be implemented.

require 'autotest/redgreen'

module Autotest::Growl
  def self.growl title, msg, img, pri=0, stick="" 
    system "growlnotify -n autotest --image #{img} -p #{pri} -m #{ msg.inspect} #{title} #{stick}" 
  end

  Autotest.add_hook :ran_command do |autotest|
    results = [autotest.results].flatten.join("\n")
    output = results.slice(/(\d+)\s+examples?,\s*(\d+)\s+failures?(,\s*(\d+)\s+pending)?/) 
    if output  =~ /[1-9]\sfailures?/
      growl "FAIL:", "#{output}", "~/Library/autotest/rails_fail.png", 2, "-s" 
    elsif output  =~ /[1-9]\spending?/
      growl "PENDING:", "#{output}", "~/Library/autotest/rails_pending.png", 2, "-s" 
    else
      growl "PASS:", "#{output}", "~/Library/autotest/rails_ok.png" 
    end
  end
end
