Unit Testing: Minutes now will save hours later

Imagine a world where your code automatically tests itself each and every
time you deploy.  Where your code can tell if anything broke since the
last time you shipped.  Where your deployment environment points out any
mistakes you made so you can fix them before a customer calls to complain.

That world exists. And you can get there today.

Drafting unit tests for JavaScript isnÎéÎ÷t glamorous, but it will save
you time down the road and make your application more robust.  Integrating
testing with an existing grunt.js workflow automates the process and makes
it that much more useful.
