This gem is deprecated. Please use terminal-notifier-guard. Install it manually

$ gem install terminal-notifier-guard

Or put it in your Gemfile

group :development do
  gem 'guard'
  gem 'terminal-notifier-guard'
end

Uses the built-in OS X Mountain Lion Notification Center to display messages. It uses a nice app by Eloy Durán that gives you command line access to the service.

Add this line to your application's Gemfile:

gem 'nsnotify'

And then execute:

$ bundle

Or install it yourself as:

$ gem install nsnotify

require 'nsnotify'

# Use the notify method
Nsnotify.notify "Testing!", "Can you see me?!"

# Or one of the other convenience methods
# (success, error, warning, pending, info, broken)
Nsnotify.success "Yeah if this works!"
Nsnotify.error "Did something go wrong?!?"

# You can set the title to your app's name
# instead of that lame Nsnotify.
Nsnotify.app_name = "MyApp"
Nsnotify.success "Yeah, see me?!"

I added a pull request for Guard integration, so you will have all your Guard notifications through the Notification Center by having the following in your Gemfile:

group :development, :test do
  gem 'guard'
  gem 'nsnotify'
end

The default onclick behavior for a notification is open/focus Terminal.app. If you want to change that to another terminal emulator you can change the app bundle identifier:

# Focus iTerm2 when clicking a message.
Nsnotify.app_bundle_identifier = 'com.googlecode.iterm2'

I put it in spec_helper.rb, and it works fine with Guard and Spork.
