Definitely check out Rails Dev Box(https://github.com/rails/rails-dev-box https://github.com/rails/rails-dev-box) too. It helps to create a virtual environment for testing and running the Rails test suite. Once you have that installed, you basically don't have to worry about dependencies that you need to bootstrap the Rails test suite.
