"Its" makes testing methods with multiple arguments much easier

Tested on MRI Ruby 1.8.7, 1.9.2, 1.9.3, Rubinius (1.8 and 1.9) and JRuby

Have you ever written something like this in your specs?

it "should be US currency" do
  subject.currency(:us).should == 'US dollar'
end

it "should be AU currency" do
  subject.currency(:au).should == 'AU dollar'
end

it "should be UK currency" do
  subject.currency(:uk).should == 'UK pound'
end

If yes, then this is what you really needed:

its(:currency, :us) { should == 'US dollar' }
its(:currency, :au) { should == 'AU dollar' }
its(:currency, :uk) { should == 'UK pound' }

Installation and use

Add to your Gemfile:

gem 'its'

Then require it somewhere:

require 'its'

And you are done.
