its(attribute, &block) click to toggle source

    # File lib/spec/example/subject.rb, line 23
23:         def its(attribute, &block)
24:           describe(attribute) do
25:             define_method(:subject) { super().send(attribute) }

subject(&block) click to toggle source

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.
