I had written the original guide for "A Guide to Testing Rails Applications". The current documents maintains the same structure and examples I had drafted albeit with some minor changes to keep up with newer version of Rails. Older version which had credits included: http://guides.rubyonrails.org/v2.3.11/testing.html Github lifo/docrails History: ff359af865/railties/doc/guides/source/testing_rails_applications.txt
