A pattern for testing class methods in ruby with rspec explicit subjects
# RSpec's subject method, both implicitly and explicitly set, is useful for
# declaratively setting up the context of the object under test. If you provide a
# class for your describe block, subject will implicitly be set to a new instance
# of this class (with no arguments passed to the constructor). If you want
# something more complex done, such as setting arguments, you can use the
# explicit subject setter, which takes a block.
describe Person do
context "born 19 years ago" do
subject { Person.new(:birthdate => 19.years.ago }
it { should be_eligible_to_vote }
