# Must have Nokogiri gem installed and save this file in your spec/support dir
# Allows you to write cleaner/faster specs in your views (50% faster than css_select)
# Increased readability in your spec doc
# ex.
# rendered.should contain('my heading').within('h1') # searches all H1 tags for 'my heading'
# or 
# rendered.should contain('my string') # searches entire rendered string for 'my string'
