Hi guys, it’s been a while that I haven’t posted anything. I was thinking writing all those technical things sometimes is not enough for the reader to visualize the concept. So I came up with a screencast this time. I’ll try to create these screencasts once a week and will cover different topics. This series will contain Making Code More Testable talks only. For other topics, I’ll create different series. Anyways, let’s get back to the overview :)

A nice modularity tip that should be considered when you’re designing a modular system:

Today I was reading an answer to a question (http://bit.ly/FkgKB) about naming the implementation classes.
