I’m a big fan of Behavior Driven Development (BDD). It really illustrates how one little change in your code can have significant impact on the rest of you application, which you would never be able to catch without testing. Not to to mention the benefit of being able to write code and make sure it works even if you don’t have production data available.
So, upon completing a clean upgrade to Leopard I noticed that after installing Growl and growlnotify, that growlnotify would not work even through Growl itself was working.
1) First let’s set up the .autotest file. For this you’ll need the gems rspec (1.1.3), ZenTest (3.9.1), and redgreen since ZenTest change how it handled exceptions in 3.9.
sudo gem install rspec
sudo gem install ZenTest
sudo gem install redgreen
Now open up your ~/.autotest file in Textmate
mate ~/.autotest
Paste in the following code. Notice the exceptions at the bottom of the file that really helps speed up autotests as well as keeps your cpu usage low. My Macbook would get really hot really fast prior to using this execptions.
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|
filtered = autotest.results.grep(/\d+\s.*examples?/)
output = filtered.empty? ? ” : filtered.last.slice(/(\d+)\s.*examples?,\s(\d+)\s.*failures?(?:,\s(\d+)\s.*pending)?/)
if output =~ /[1-9]\sfailures?/
growl “Test Results”, “#{output}”, “~/Library/autotest/rails_fail.png”
elsif output =~ /pending/
growl “Test Results”, “#{output}”, “~/Library/autotest/rails_pending.png”
else
growl “Test Results”, “#{output}”, “~/Library/autotest/rails_ok.png”
end
end
end
Autotest.add_hook :initialize do |at|
%w{.svn .hg .git vendor}.each {|exception| at.add_exception(exception)}
end
Next, you’ll want to download the Pass, Fail, and Pending images below and place them in ~/Library/autotest:
First, the prerequisite to growlnotify is Growl. You can download it from http://growl.info/. It’s a graphical installer, so you shouldn’t have an issues.
Once you’ve installed Growl, pop open the terminal and enter the following commands.
cd /Volumes/Growl 1.1.2/Extras/growlnotify
sudo sh install.sh
Give it a test run:
growlnotify -m “Testing growlnotify” Test
So if that doesn’t work, it’s probably because of an issue with the default permissions and Mac OS X 10.5 Leopard. Here’s what my permssions were. (I have no idea why the @ symbol is there)
cd /usr/local/bin
ls -l
-rwxr-xr-x@ 1 ryan 501 130288 Jan 22 17:38 growlnotify
To fix the permissions, I ran the following:
sudo chown root:admin growlnotify
Resulting in the following permssions:
cd /usr/local/bin
ls -l
-rwxr-xr-x@ 1 root admin 130288 Jan 22 17:38 growlnotify
Give it a test run again:
growlnotify -m “Testing growlnotify” Test
Now you can change directories to your rails app and run autotest and growlnotify should be working now..
cd ~/myrailsapp
autotest
