Could you please elaborate for dummies like me what is guard in Ruby land please?

Guard is a gem - github.com/guard/guard

It has plugin like guard-rspec.

What Guard does is it watches a number of files and restart your server when needed (changing Gemfile, routes etc).

Guard-Rspec add to that by watching your test files and automatically running them when you save

and restart your server when needed (changing Gemfile, routes etc)

I did not start the server in years. Why would I need to ever start a server when I have tests?
