I've been trying to get into TDD myself for years. I've read the 2 most suggested books and another book that had "testing" in it. But I still came back with issues. I don't program Java, so I don't understand some of this code, so I can't just convert it over to the languages I know. The examples were of basic stuff like "Lets make something that adds two numbers", "Here's a basic mock, lets not worry about DB queries", etc... It really didn't teach me how to think in TDD, it wasn't specific for the languages I program in, nor did it touch on things like "real time data" coming from a stream source, which I think is "How to think in TDD and how to program to fit it."
