Getting Insurance
The easiest way to get Insurance is to use Ruby Gems:
$ gem install insurance
Setting up your Rails application
Use the railscov command to install a Rake task into your
Rails application directory.
$ railscov -A MyRailsApp
Running Insurance on your Rails application
Use the installed Rake task.
$ rake insruance
This will generate an insurance/ directory with an HTML
file for each file in your project. Lines of code that were not
executed will be marked with a red tinted background.
