assert_dom_equal(expected, actual, message = nil)

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

# 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")
# File actionpack/lib/action_dispatch/testing/assertions/dom.rb, line 10
def assert_dom_equal(expected, actual, message = nil)
  expected_dom = HTML::Document.new(expected).root
  actual_dom   = HTML::Document.new(actual).root
  assert_equal expected_dom, actual_dom, message
end
assert_dom_not_equal(expected, actual, message = nil)

The negated form of assert_dom_equivalent.

# 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")
# File actionpack/lib/action_dispatch/testing/assertions/dom.rb, line 20
def assert_dom_not_equal(expected, actual, message = nil)
  expected_dom = HTML::Document.new(expected).root
  actual_dom   = HTML::Document.new(actual).root
  assert_not_equal expected_dom, actual_dom, message
