railstutorial.org - undefined method `Factory'

Question

I\'m attempting to follow railstutorial.org, and am currently on Chapter 7, where you start using factories: http://railstutorial.org/chapters/modeling-and-viewing-users-two#sec

Answer 1

(I've listed it here, because it might help someone who doesn't follow the tutorial correctly)
