From 839a1426ce2a8510cdf0e648b06f28e7c33b64b6 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Tue, 1 Dec 2015 11:24:20 +0100 Subject: tests/kms_force_connector: Include in BAT set Forcing connector state is a basic piece of our test infrastructure that we use in all the kms_ tests. It allows us to run tests even if no outputs are connected. They're also really fast, so perfect candidates for inclusion into the BAT set.
