is assert_select_rjs deprecated in Rails 3.1 ?

I have seen it in 3.0.9 doc ( http://apidock.com/rails/v3.0.9/ActionDispatch/Assertions/SelectorAssertions/assert_select_rjs ) but it's not mentioned in the latest guide ( Testing Rails Applications — Ruby on Rails Guides)

if deprecated how can I check the view from an Ajax call ( assert_match + gsub could work ? ... ) am I missing any doc ?

xhr :get, :change_area, { :area => south_west.id}

thanks for feedback

I have seen it in 3.0.9 doc (APIdock… ) but it's not mentioned in the latest guide (Testing Rails Applications — Ruby on Rails Guides)

All of rjs (including assert_select_rjs) was removed from rails 3.1 and extracted into prototype-rails ( GitHub - rails/prototype-rails: Add RJS, Prototype, and Scriptaculous helpers to Rails 3.1+ apps ) plugin
