If a little decomposition is good, then A LOT of decomposition is better right? Well, maybe not :) In this talk, we'll take a look at understanding the intent behind Dependency Injection, understand the value of following the Single Responsibility Principle in our OO designs, and investigate the trouble that blind adherence to this pattern can often cause in our projects.

Effective unit testing is more art than science -- in this talk we'll look at both Patterns and Anti-Patterns for writing, organizing, and designing efficient, effective unit tests that help to ensure your tests continue to add value to your project throughout its evolution rather than becoming an anchor that weighs down your progress and impedes your speed! Learn both what to do and what NOT to do from someone who has been writing unit tests for over ten years!

In this session we take a small, functional but tightly-coupled, software solution and improve its design using each of Robert C. Martin's S.O.L.I.D. principles. Each principle is applied in sequence to the existing solution, making it possible for the attendee to observe the principle in relative isolation first while also evolving an understanding of how the principles all collaboratively reinforce each other when applied together.
