Run growl with mocha tests, MacOS

mocha is a great testing framework. It has a flag to use growl notifications. The command to run using the watch feature and growl:

$ mocha --growl --watch

This way you are supposed to be able to run the tests on the background and get notifications through growl.

It took me a second to realize that in order to actually get the notifications you have to install a separate node-growl module from npm.

There is also a dependency on a gem terminal-notifier:

$ sudo gem install terminal-notifier
