Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment. ```bash bin/console Aaa::Bbb::Program.execute() # => "" ``` `cmdlet` is setup with Guard, run `guard`, this will watch development file changes and run tests automatically, if successful, it will then run rubocop for style quality.
