assert_dom_equal(expected, actual, message = "") click to toggle source

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")

    # File lib/action_dispatch/testing/assertions/dom.rb, line 13
13:       def assert_dom_equal(expected, actual, message = "")
14:         expected_dom = HTML::Document.new(expected).root
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)
17: 
18:         assert_block(full_message) { expected_dom == actual_dom }
19:       end

assert_dom_not_equal(expected, actual, message = "") click to toggle source

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")

    # File lib/action_dispatch/testing/assertions/dom.rb, line 28
28:       def assert_dom_not_equal(expected, actual, message = "")
29:         expected_dom = HTML::Document.new(expected).root
30:         actual_dom   = HTML::Document.new(actual).root
31:         full_message = build_message(message, "<?> expected to be != to\n<?>.", expected_dom.to_s, actual_dom.to_s)
32: 
33:         assert_block(full_message) { expected_dom != actual_dom }
34:       end
