While writing functional test cases, we might need a common utility to be used through our test cases. These utility is generally recognized as "Macros" and more specifically as "Controller Macros". With Rspec we can easily configure such Macros, as Rspec specifically provide a RSpec.configure block to define all our utility and support classes/modules used throughout our test suit. The RSpec.configure block looks like this. RSpec.configure do config.extend(AuthenticateMacro) end With Test::Unit which is a default testing tool provided by rials and its much more liter than Rspec, we can't
