Is there a service or website that I can use to test a client implementation of the OAuth 2.0 protocol? The question linked above points to some excellent resources but they currently implement v1.0 of OAuth.

You can run your very own Django OAuth 2.0 Server or Rack OAuth 2.0

There is also Apache's Amber Authorization Server
