Use string value when setting the class attribute explicitly.

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.

Examples

# bad
factory :foo, class: Foo do
end

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