I've read a lot about TDD and I've tried to develop using TDD without success ... I always stop staring at the screen...I've learned that I should not write tests for methods or class. I should write tests for behaviors. That's because objects interact with each other and this interaction should be tested.Following the example bellow:Imagine that, I, as a company owner, would like to save my customers information  to consult that later.That's my business value.Just to learn, I would not like to use any framework or library, just plain PHP and PHPUnit.Ok, now, where should I start?I think that my users must enter an url to go to the form ... So should I test if it's loading the page? Is this a good start? If it's true, how could I test it?
TDD: Where should I start?
