Grunt has a task to watch current folder. I just stumbled across these
commands by luck but they seem to create a nice simple flow to get
started testing and writing code.
(enter .git for git repo path)
Now you have a grunt managed project!
I then ran:
and opened a new terminal pane using iTerm2 in the same window ⌘D
then, opened vim and changed lib/Grunts.js to return axxxsome instead
of 'awesome'. Voila the other pane that is `watching` spits out a nice
list of trace statements. It runs /nodeunit/ tests but still, if i'm
starting out, I think this is easier than getting a similar workflow
working without ruby.
