We are going to build and test a command line app that does Rock, Paper, Scissors.
Testing command line applications is hard because we are getting and printing things out to the system. We need to find a ways to inspect or divert that process in order to test our application.
Before trying this on your own, you should have seen a lecture where we did this together. If not, use the assessment, todo-cli, as a reference for writing tests.
It only comes with the 'rspec' gem for testing. It also comes with files that set the ruby version and the gemset. Once you pull down this project once, and bundle gems, you shouldn't have to do it again. Your computer should just know which Ruby and gemset to use.

- Test your real logic, and then make the tests pass one at at time
