As part of an application I am developing, I have been delving into the dark art of Rails testing. Since the existing literature on the topic is a bit sparse, I have written up a couple of brief articles on testing strategies for rails. The first one is on the usefulness of ''Positive and Negative Controls'', and the other is a simple way to make sure you are working with valid or invalid objects in your tests.
