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 vendor/rails/actionpack/lib/action_controller/assertions/dom_assertions.rb, line 11 11: def assert_dom_equal(expected, actual, message = "") 12: clean_backtrace do 13: expected_dom = HTML::Document.new(expected).root 14: actual_dom = HTML::Document.new(actual).root 15: full_message = build_message(message, "<?> expected to be == to\n<?>.", expected_dom.to_s, actual_dom.to_s) 16: 17: assert_block(full_message) { expected_dom == actual_dom } 18: end 19: end
The negated form of assert_dom_equivalent.
