Hi, Weston doesn't have any kind of autolaunch feature, but there are interested people at least for the desktop use case. Weston's own test suite uses a custom plugin to launch test clients, but it's not installed. That might be a better approach for a test suite than a generic desktop app autolaunch, since you can make the compositor quit and forward the test app exit code. That plugin is at tests/weston-test.c, and it implements also a test protocol, but the most relevant part for you is idle_launch_client(). test_client_sigchld() handles quitting Weston. We could think of some kind of arrangement to allow using Weston/headless to run automated tests in other projects out-of-the-box. Maybe the idle_launch_client() functionality could be integrated in the headless backend directly... but then we need more changes in Weston's test suite to allow running the tests with different backends. Maybe that would be a slightly longer term plan. Are you only looking for headless launching of apps, or would you be interested in more features like screenshooting or fake input events to drive and check tests? Thanks, pq
