| This test: |
| 1. Checks that ambient light sensor exists if specified in powerd prefs. |
| 2. Checks that the default brightness after initial boot is reasonable. |
| 3. Changes the brightness level to min (0%) and max (100%). |
| 4. Checks that the brightness level resets after rebooting the device. |
| |
| The test fails if: |
| -Ambient light sensor does not exist even though specified in powerd prefs. |
| -Initial brightness is not reasonable. |
| -Device not able to change brightness to min and max levels. |
| -Device not able to set the brightness level to default after reboot. |
| |
| Note: for devices with ambient light sensor, test will allow for a small change |
| in internal display brightness; test will fail if internal display brightness |
| changes drastically. |
| |
| Example usage: |
| test_that -b <board> <host> power_BrightnessResetAfterReboot |
