Heroku emulation on a local computer

Question

I'm new to Heroku and Ruby on Rails, and this may seem trivial. But I could not find the answer.

Google App Engine has a web server application that emulates all App Engine services on the local computer. Does Heroku have something similar?

Basically I want to run / debug the RoR application on the local machine before pushing it to Heroku.
