Testing with Ruby

To get started with Ruby testing, I am using RSpec ruby framework.
http://rspec.info/

To use RSpec, first you will need to have the gem "guard" which is a command line tool to work with RSpec.
$ gen install guard.

$ bundle exec guard list
This will give you a list of frameworks installed and ready for guard to work with.

After that run
$ bundle exec guard.

This will take you to the guard prompt . Do the following to run all tests.

$ guard(main)> all rspec.

You are up and running!
