Everyone can test patches. Really! simplytest.me to the rescue!
It's blazing fast, and it fills in the info about the database and user for you during the install screens.
To Test Drupal 8
For the project name, type drupal, and then for the version, scroll down and look for 8.x under Branches.
To get a patch url
Go to an issue number, for example: http://drupal.org/node/1833022 (a confusing multilingual screen). Then I skip to the end and find the most recent patch.
On my Mac, I command-click and copy the url address. But one could just highlight the address and copy it.
