Still in early development stages, to install:
npm install -g automocha
Automocha will use mocha to autorun any tests contained within
./test/automocha/ and end in -test.js. Automocha will
then watch all of the test files and any files specified on the
command line for chages and rerun mocha on change.
ex:
automocha ./lib/**/*.js
Will run all of the tests found in ./test/automocha and when any of the
test files change or any of the javascript files in ./lib change it will
rerun all of the tests.
