        def its(attribute, &block)
          describe(attribute) do
            define_method(:subject) { super().send(attribute) }
            it(&block)
          end
        end
subject (&block)

Defines an explicit subject for an example group which can then be the implicit receiver (through delegation) of calls to should.

Examples

describe CheckingAccount, "with $50" do
  subject { CheckingAccount.new(:amount => 50, :currency => :USD) }
  it { should have_a_balance_of(50, :USD) }
  it { should_not be_overdrawn }
  its(:currency) { should == :USD }
end

See +ExampleMethods#should+ for more information about this approach.
