Doms are compared via `assert_dom_equal` and `assert_dom_not_equal`. Elements are asserted via `assert_select`, `assert_select_encoded`, `assert_select_email` and a subset of the dom can be selected with `css_select`. The gem is developed for Rails 4.2 and above, and will not work on previous versions. ## Nokogiri::CSS::SyntaxError exceptions when upgrading to Rails 4.2: Nokogiri is slightly stricter about the format of CSS selectors than the previous implementation. Check the 4.2 release notes [section on `assert_select`](http://edgeguides.rubyonrails.org/4_2_release_notes.html#assert-select) for help. ## Installation Add this line to your application's Gemfile: gem 'rails-dom-testing' And then execute: $ bundle Or install it yourself as: $ gem install rails-dom-testing ## Usage ### Dom Assertions ```ruby assert_dom_equal '
