Test coverage: How many models have factories - not all will need them of course. I'm definately not implying that all of the models are going to need factories!

factories_to_make.rb

#for running in the console
require 'factory_girl'

models = []
factories = []

#otherwise this list isn't going to contain all models.
Rails.application.eager_load!
 
ActiveRecord::Base.descendants.each do |model|
  models << model.name
end

#Record the factories in use. Fac Records!
#(And exclude the subfactories indicated by _)
FactoryGirl.factories.each{ |fac| factories << fac.name.to_s.capitalize unless fac.name.to_s.include? "_" };nil

todo = models - factories

puts "We have #{models.count} models. We have #{factories.count}. Potentially we have #{todo.count} factories to create."
todo.sort.each{ |model| put model + "," }
