Spring speeds up development by keeping your application running in the background.
When Spring is enabled, cache_classes
should be set to false
# config/environments/test.rb​class Application < Rails::Applicationconfig.cache_classes = falseend
# config/spring.rb​Spring.watch('.ruby-version','.rbenv-vars','tmp/restart.txt','tmp/caching-dev.txt')
# Gemfile​group :development dogem 'spring'gem 'spring-watcher-listen', '~> 2.0.0'end
