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