This gem can print simple statistics on your factory_girl factories when using rspec.
Add this line to your application's Gemfile:
gem 'factory_stats', require: false, :github => 'liefery/factory_stats'And then execute:
$ bundle
Go to your spec_helper.rb (or where ever else, that runs before the rspec examples and after factory_girl is required) and add the following:
require 'factory_stats' if ENV['FACTORY_STATS']$ FACTORY_STATS=1 rspec
Example output:
