FactoryStats

This gem can print simple statistics on your factory_girl factories when using rspec.

Installation

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']

Usage

$ FACTORY_STATS=1 rspec

Example output:

-- Address factory calls: --
create: 1100
 10.370000   1.640000  11.010000 ( 13.088933)

  0.050000   0.010000   0.060000 (  0.065872)
