See stuff about a Rails app.
There were a few things missing to the included rake stats
RailsStats mainly adds the ability to be run from outside the project in question. This can be helpful if the app you are interested in can not be booted for some reason.
You will need a Rakefile in the directory where you call rake and you will
need to require rails_stats:
# Rakefile
require "rails_stats"Then you can call it:
$ rake stats\[/path/to/app/\]
Directory: /path/to/app/

Just add rails_stats to your Gemfile.
Depending on your setup, you might need to require rails_stats in your Rakefile.
Then you'll be able to just run:
$ bundle exec rake statsRailsStats adds more coverage than the default.
- Any concepts you've added within an
appdirectory - Configuration files
- Library files
- Gems that you've created and embedded in the project
- Engines and their code
- RSpec/Unit/Cucumber Tests
Here are some open source Rails projects and their output.
