Summary: The addition of the test infrastructure is motivated by the regressions caused by adding mode switching and transformation support. A contributing factor to these regression is the fact that the DRM platform does not have any tests. It is difficult to test this code as it needs to work with hardware, thus we cannot use the real DRM library. Instead we need to use mocking. This change sets up some first basic tests with the help of a mockDrm library. In order to better test the code as units the Drm classes are slightly refactored. Most importantly the dependency to DrmBackend is removed wherever possible and replaced by a simple int fd which is mostly the only element used by the classes. This first test introduces basic testing of a DrmObject. It is intended to extend this to at least also test DrmPlane as a central piece of our Drm platform plugin. This will also extend the tests of DrmObject. Reviewers: #kwin, #plasma Subscribers: plasma-devel Tags: #plasma Differential Revision: https://phabricator.kde.org/D8776
