How can we cover unit testing for the library?

Right now, the only way to develop this is by hitting the live Cloud Datastore API. Is there a way we can use these API calls in unit tests without mocking?

Can we have a "local datastore" server that understands the API and makes it easy for local development?

Use gcd dev server?

Having a conversation over here: googleapis/google-cloud-python#2

I think the issue really is more about in-memory testing -- a stub service would be really nice to expose (along the lines of how dev_appserver.py in App Engine does it) like with google.appengine.ext.testbed.
