# 1. add this to formtastic_spec.rb inside the ":as => :select" describe block

it 'should have one option with a "selected" attribute' do
  output_buffer.should have_tag('form li select option[@selected]', :count => 2) # the 2 is intentional
end

# 2. run the specs

expected
<form class="formtastic post" action="/posts" method="post" id="new_post"><li class="select optional" id="post_author_id_input"><label for="post_author_id">Author</label><select name="post[author_id]" id="post_author_id"><option value="37">Fred Smith</option>
<option selected="selected" value="42">Bob Rock</option></select>
</li></form>
to have 2 elements matching "form li select option[@selected]", but found 1

# 3. change the spec to only look for one

it 'should have one option with a "selected" attribute' do
  output_buffer.should have_tag('form li select option[@selected]', :count => 1)
end

# 4. run the specs, they pass
