I'm no longer maintaining this plugin. Feel free to fork it and do what you wish with it, but I won't be updating it anymore.
This is a simple rails plugin for Rails 3 that adds some useful rcov rake tasks.
rake test:coverage # Tests coverage on the entire application rake test:coverage:units # Tests coverage for unit tests rake test:coverage:functionals # Tests coverage for functional tests rake test:coverage:integration # Tests coverage for integration tests
The task ends up creating a coverage folder with an html coverage report in it.
SHOW_ONLY is a comma-separated list of the files you'd like to see (although you can only run functionals, you still see all the models and helpers which are 'touched'). Right now there are four types of files rake test:coverage recognizes: models, helpers, controllers, and lib. These can be abbreviated to their first letters:
rake test:coverage SHOW_ONLY=models rake test:coverage SHOW_ONLY=helpers,controllers rake test:coverage SHOW_ONLY=h,c
As of Rails 3, rake tasks can be distributed easily in plugins packaged as gems, and that's what we do here. So, to install rcov_plugin, simply do:
gem install rcov_plugin
or add the gem to your bundler Gemspec
rcov_plugin works great with JRuby.
If using JRuby, remember to run rake with it, like this: jruby -S rake test:coverage
Special thanks go to Leonard Borges (http://www.leonardoborges.com) for getting the plugin working with JRuby.

This plugin worked with Rails 2 back in the day, and I've got a tag on the repo that you can use to install the old Rails 2 version. Use the following command:
script/plugin install -r refs/tags/rails_2 git://github.com/commondream/rcov_plugin.git
Special thanks go to all of the contributors to this plugin:
