2. Find the smallest difference
3. Make the smallest change that make the tests pass

Useful for when you need to have two hosts talk to each other on a specific port but they're both NATed (behind routers).  
For example, you want to be able to SSH into your friend's machine to pair program with them.

host-machine$ ssh -R 55555:localhost:22 myaccount@my_ssh_server.com

connecting-machine$ ssh -L 55555:localhost:55555 myaccount@my_ssh_server.com
connecting-machine$ ssh -p 55555 user_on_host_machine@localhost
