This repo contains code for you to test your solution two different ways. One is to use RSpec and the other is to run ad-hoc tests with ruby code written for you.
To run the specs simply run rspec spec/mass_object_spec.rb
To run the ad-hoc tests simply run ruby test/ruby_mass_object_test.rb
These specs are to act as a basic guide to show you how one would use the framework you're building.
