CakePHP + Watchr

watchr.rb

###
#
# Watchr Configuration.
#
# This is used to watch the entire application's folder for modifications to
# models, controllers, tests, configuration files and logs. For logs, notify
# with log file's name. For the rest, run appropriate test(s) and notify of
# results. Test results also appear on the terminal window where you launched
# `watchr`.
#
# Inspired by http://www.amitsamtani.com/2010/05/09/cakephp-autotest-using-watchr/
#
# Requires the `watchr` gem. If you don't have it, run:
#
#    gem install watchr
#
# The `watchr` configuration file (this file) needs to be stored in `app/Config`
# and used when starting the `watchr`:
#
#    watchr app/Config/watchr.rb
#
# It is assumed that you also have the required images:
#
#    app/Config/.watchr_images/passed.png
#    app/Config/.watchr_images/failed.png
#
