Override the equality operator in your Ruby classes
Test driven development by example is a wonderful book. It could only be better if the examples were all in Ruby :).

Fear not, because I’ve just blogged about how to override the equality operator in ruby, at the same time, throwing in some extra goodness of test driven development.
