# This cop would promote faster tests by lazy-loading of
# application files. Also, this could help you suppress potential bugs
# in combination with external libraries by avoiding a preload of
# application files from the factory files.

# @example
# # bad
# factory :foo, class: Foo do

# # good
# factory :foo, class: 'Foo' do
