The visitor segmentation and light javascript implementation are perfect for small to medium size environments, looking to improve the OOTB reporting.

My buddy and fellow SharePoint Junkie/MVP, Andrew Woodward, has put together a nice white paper which walks you through the steps necessary to get started with Test Driven SharePoint Development.

This paper is the first in a series that he is putting together, so keep an eye on his blog or better yet, subscribe.
