From b2b3599b5b0673901bbce958bd9802b9d6313fcf Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Tue, 11 Jun 2019 16:13:39 +0300 Subject: tests: Add CameraSensor class test MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add a test to verify media bus codes, sizes and resolution retrieval through the CameraSensor API based on the Sensor A in the vimc pipeline. Also check that the getFormat() method returns the expected media bus code and size.
