From 257df552a454d7afdc339ef88040e986400d2d89 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Niklas=20S=C3=B6derlund?= Date: Mon, 24 Feb 2020 20:12:45 +0100 Subject: test: Extract BufferSource class out of camera tests to libtest MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The BufferSource class can be used by other tests other then the camera buffer importer test, move it to libtest. The only changes to BufferSource is for it to be allowed to be split in a header and source file. This change makes it necessary for libtest to have access to internal libcamera headers. As the internal headers already are accessible to all test cases this does not increase the exposure of libcamera internals to the test cases.
