I am starting work on a personal project which should (hopefully) develop into a startup, the project will need to scale well and I would prefer to invest the time now in TDD.
I am a big Lithium fan, and I am aware that Lithium have their own built in test suite, but I can't find any solid documentation on it and I have never done any real TDD before.
Is there a better way for me to go? Or should I just stick in with Lithium and grind the learning process?
EDIT: Just to clarify. I am talking about PHP Frameworks, not testing frameworks.
