screen_is_not_black_test reboots the device under test and verifies that its screen is not black within 100 seconds after reboot.
This test is enabled for the terminal and workstation products.
The test can optionally start up tiles before checking the screen. Use this mode for configurations that do not start up any graphical environment on boot but are capable of running tiles, like the terminal product.
Test targets:
screen_is_not_black - Reboots the device and examines the screen without starting any additional programs. Use this in configurations that start up a graphical environment by default.
tiles_test - Starts tiles and verifies the screen is not black on products that use it. This will cause root_presenter to start as well.
