RcovRails
A simple "no thoughts required" solution to adding RCOV code coverage to your Rails application.
Just install the plugin, install the RCOV gem, and you're done.
Enjoy.
Example
Install as a Rails 3 Gem:
$: vim Gemfile
group :development do
gem "rcov_rails"
end
$: bundle install
$: rake test:coverage # boom!
Install as a Rails 2.x Plugin:
$: sudo gem install rcov
$: ruby script/plugin install git://github.com/matthewrudy/rcov_rails
$: rake test:coverage # boom!
Install as a Rails 3.x Plugin: // I suggest you don't do this, as you'll need to add rcov via bundler anyway
$: sudo gem install rcov
$: vim Gemfile
group :development do
gem "rcov"
end
$: bundle install
$: rails plugin install git://github.com/matthewrudy/rcov_rails
$: rake test:coverage # boom!
