coco

Coco is another code coverage utility for Ruby 1.9. One uses it from rspec or unit/test with a simple "require 'coco'". It displays the names of files that are covered less than 90% on the console. It builds a simple HTML report only for files covered less than 90%. It reports sources that have no tests. It is UTF-8 compliant. It is configurable via a simple YAML file. It has colorized console output.
