def assert_dom_equal(expected, actual, message = "")
  expected_dom = HTML::Document.new(expected).root
  actual_dom   = HTML::Document.new(actual).root
  full_message = build_message(message, "<?> expected to be == to\n<?>.", expected_dom.to_s, actual_dom.to_s)

  assert_block(full_message) { expected_dom == actual_dom }
end
assert_dom_not_equal(expected, actual, message = "")

The negated form of assert_dom_equivalent.

Examples

# assert that the referenced method does not generate the specified HTML string
assert_dom_not_equal '<a href="http://www.example.com">Apples</a>', link_to("Oranges", "http://www.example.com")
