BBB001.001 Boot blocking (charger disconnected) (Ubuntu 22.04)

Test description

This test aims to verify that booting is blocked when the battery level is below 5% with charger disconnected from the DUT.

Test configuration data

1. FIRMWARE = Dasharo
2. OPERATING_SYSTEM = Ubuntu 22.04

Test setup

1. Proceed with the Test cases common documentation section.

Test steps

1. Make sure the charger is not plugged into the DUT.
2. Power on the DUT.
3. Boot into the system.
4. Log into the system by using the proper login and password.
5. Open a terminal window and install stress-ng package by executing following command:

sudo apt install stress-ng

1. Open a terminal window and run following bash script:

get_battery_level() {
    battery_level=$(cat /sys/class/power_supply/BAT0/capacity)
    echo "$battery_level"
}
target_battery_level=3
while true; do
    current_battery_level=$(get_battery_level)
    echo "Current battery level: $current_battery_level%"
    if [ "$current_battery_level" -le "$target_battery_level" ]; then
        echo "Battery level reached 3%. Stopping stress-ng."
        break
    fi
    stress-ng --cpu 0 --timeout 10s
done

1. After the script finished working, reboot the DUT.

Expected result

1. The bash script reads current battery charge level and stresses the CPU until the battery charge level reaches below 5%. Example output:

Current battery level: 92%
stress-ng: info:  [25309] setting to a 10 secs run per stressor
stress-ng: info:  [25309] dispatching hogs: 16 cpu

1. After reboot, booting into the OS should be blocked and following warning message should appear:

        echo "Battery level reached 3%. Stopping stress-ng."
        break
    fi
    stress-ng --cpu 0 --timeout 10s
done

1. After the script finished working, plug the charger into the DUT.
2. Reboot the DUT.

Expected Result

1. After reboot, the warning message should not appear and the DUT should boot normally.
