# The discussion is about two styles of interfaces.
# The first option is to use enumerable to make it look like an array
# The second option is to just return another array
# Of course in real life the class does more than this, this is just an example.

# What is your preference or opinion on this? Please comment :)

# option 1: include Enumerable:

SpecCoverage formatter

This formatter loads SimpleCov a code coverage reporting tool for Ruby 1.9. SimpleCov already does a good job in making it really easy to configure and load itself, but even good efforts can be improved upon.

The only problem is that you'll need to have something like a spec_helper to load it. You might not have this or you might find it ugly having to resort to environment variables to turn it off or on.

With this formatter, SimpleCov will start, and it will load a .coverage file in which you can add ruby code to configure SimpleCov in a non-obtrusive way. Configuration for a typical Rails app will look like this:

SimpleCov.start 'rails'
