Same error. Running Multi-Site. WordPress 3.6.1.
Turn off your other plugins and try again. Normal troubleshooting steps apply.
Same issue here. Wp 3.7. Deactivated all other plugins and issue persists.
Same problem here with 3.7
However after upgrading to 3.7.1 via the update page, the plugin no longer has this problem and the plugin tester page reports everything is clear.

Same here. Wish I’d thought to try that.
I had this problem as well. In my case, it was caused by a missing file: /wp-admin/includes/class-wp-upgrader-skins.php
I’ve no idea how that file came to be missing. <edit>On closer inspection, I found that the site was still running 3.6.1.</edit>
( ! ) Fatal error: Class ‘Automatic_Upgrader_Skin’ not found in C:\wamp\www\t2k\wp-content\plugins\background-update-tester\background-update-tester.php on line 251
