Instance Method Details

#arg(name, position = nil, &block) ⇒ Object

TODO support anonymous positional: arg(0) { ‘0’ }

Examples:


describe Thing do
  arg(:first, 0) { '0' }
  arg(:second, 1) { '1' }
  arg(:kw_arg) { 3 }
  arg_block(:blk) { proc { 'body' } }

  # `subject` is now: Thing.new('0', '1', kw_arg: 3, &blk)

  it { is_expect(subject).to be_a(Thing) }
  it { is_expect(subject.perform).to be_nil }
end
