@esolve esolve: the answers above from adrelanos and Julian are correct.

Just get a VPS trial service for few days, free Amazon EC2 or something similar
- that's easiest way for testing.

Though from pure technical point it's possible to connect to "localhost", but
it's much more work compared to just renting a VPS. It's like building your own
"one-hop" Tor network:

- you need to run a local Tor OR node with modified code (DEFAULT_ROUTE_LEN in
src/or/or.h must be lowered => requires recompilation of Tor binary)
- node has been set to not publish descriptor ("PublishServerDescriptor 0" in
torrc)
- do some mucking with local DNS resolver, e.g. install bind/unbound/dnsmasq
locally, point your computer's DNS settings to it and set a custom domain to
resolve myspecialdomain.blabla to some "local" address - you also may have to
assign or create an network interface with "spoofed" non-private IP address
(i.e. outside of adresses like 127/8, 192.168/16, etc).

I did some development this way (more details, but may be outdated:
https://github.com/hiviah/tor-devel-environment). But as I said the VPS way is
just so much easier, so is the hidden-service way mentioned above - which seems
what you are after.

There's also Shadow but I didn't try it yet (https://shadow.cs.umn.edu/).
