Not Receiving Growl Messages from Autotest on Windows

I am following the Ruby on Rails Tutorial (http://ruby.railstutorial.org) . In Chapter 3, the author covers testing. Everything seems to be working according to the instructions, but I don't get Growl notifications (green or red) after starting autotest. Also, in Growl, it says "No Applications Have Registered Yet".

References:

I tried both gem installs mentioned in the autotest-growl readme
I blindly loaded the gem karl-autotest-growl, although the blog describing it, although clearly written, is a bit dated
ph7spot has a fairly [detailed walkthough][4] to setup autotest for linux, windows, and xos (http://ph7spot.com/musings/getting-started-with-autotest)

My setup:

Windows 7 64bit
Growl v2.0.6 (build 2.0.6.1)

c:\Sites.autotest file contents:

    require 'autotest/growl'
    require 'autotest/fsevent'
    require 'redgreen/autotest'
    require "test_notifier/autotest"

gemfile contents:

    source 'http://rubygems.org'

    gem 'rails', '3.0.7'
    gem 'sqlite3-ruby', '1.3.2', :require => 'sqlite3'

    group :development do
      gem 'rspec-rails', '2.5.0'
    end

    group :test do
      gem 'rspec', '2.5.0'
      gem 'webrat', '0.7.1'
      gem 'win32-process'
      gem 'spork', '0.9.0.rc5'
    end

"gemfile list" output: (partial)

autotest (4.4.6)
autotest-growl (0.2.9)
autotest-rails (4.1.0)
autotest-rails-pure (4.1.2)

Please let me know if you have any questions or suggestions on how I could troubleshoot the issue.

Thanks.

Solution

The .autotest file path is not correct. It should be:

C:\sites\sample_app\.autotest

Also you need to remove the require 'autotest/fsevent' line from the .autotest file as it is for OSX only.
