Test two HTML strings for equivalency (e.g., identical up to reordering of attributes)

Examples

# assert that the referenced method generates the appropriate HTML string
assert_dom_equal '<a href="http://www.example.com">Apples</a>', link_to("Apples", "http://www.example.com")

Source Code

# File action_controller/assertions/dom_assertions.rb, line 11
def assert_dom_equal(expected, actual, message = "")
  clean_backtrace do
    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
