From d85767a8c82df0ad8530800172d7bae4f837d6d8 Mon Sep 17 00:00:00 2001 From: Jacopo Mondi Date: Fri, 11 Jan 2019 09:59:03 +0100 Subject: test: media_device: Make MediaDeviceTest a MediaDevicePrintTest As a new class for test link handling will be added as a separate test, it makes no sense to have a generic "MediaDeviceTest" class. Rename it in "MediaDevicePrintTest", and make it run only printing test.
