Thank you Michael, you are perfectly right in reminding me this. At
this particular point in time I'm not yet architecturally foresighted
enough to be able to do that. While I was writing the design documents
I did write the list of methods each object would have needed and from
that description theoretically I could have made the tests first. In
practice, while eventually writing the code for those methods, I've
come to realize that there was a large amount of variance between what
I -thought- I needed and what I -actually- needed. So, had I written
the test before, I would have had to rewrite them again. That been
said, I agree that writing the tests before must be my goal. I hope
that as my experience increases I'll be able to know beforehand the
behaviors I need from each method/object/module of my applications.
One step at the time I'll get there... =)
