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

19:       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
