I have recently created a subdomain for testing my changes on a live server. Today I have found that Google has indexed nearly a third of this test domain. How did Google find this test subdomain? There are no links to it, there's not wordpress blog (so no pinging of Google when a blog post is made), and it's not been registered in Webmaster Tools.
The only explanation I can think of is Google's free DNS has captured the subdomain address when it propagated around the 'net and is using that to index new websites.
I've added order deny,allow to my .htaccess file to block Google (and any visitors who come from the search results), but my question is: Is Google using the DNS records to find new websites? If not, how did Google find my website?

They are registered to sell domains. I'm sure they use a wide variety of crawling methods including keeping track of currently registered domainscalong with DNS data.
I dont think so, Google says
Google DNS is not used in web ranking, data is not shared with 'other
parts of google'
Google finds websites lots of different ways. They definitely don't wait for a webmaster to submit the site to them.
They could be, and probably are, using DNS. Also, if anyone with something that reports back to Google (ie analytics if it is installed, possibly Chrome, Google toolbar, etc) visits a URL on that subdomain Google will know about it.
