The test is currently not hooked up, but it pulls the latest 4.9.x kernel image, builds a simple kernel module against it and then creates a test package containing the kernel module and a shell script. The shell script prints out the 'modinfo' and then tries to 'insmod' the module. It checks the output of 'dmesg' of the load succeeded. Signed-off-by: Rolf Neugebauer <rolf.neugebauer@docker.com>
