Another COde COverage for ruby 1.9 (from the famous post of Aaron Patterson). This one suits my needs.
Use it from rspec with a simple require 'coco'
Display filenames covered < 90% on console
Build simple html report only for files covered < 90%
Report sources that have no tests
Configuration could be done via a simple yaml file
More features to come, see issues
at the beginning of your tests, usually in a *helper*.rb file.
ruby >= 1.9.2
GPLv3, see COPYING.
Feel free to email Xavier Nayrac with any questions.
