| <h2>Description</h2> |
| <p> |
| <strong> |
| This test is only useful on devices that expose the BatteryManager interface, |
| but lack a backend implementation. |
| </strong> |
| </p> |
| <p> |
| This test validates that all of the BatteryManager attributes exist and are set to their default values. |
| </p> |
| |
| <h2>Preconditions</h2> |
| <ol> |
| <li> |
| The implementation is unable to report the battery's charging state, |
| charging time, level or remaining time respectively. |
| </li> |
| <li> |
| The device is unplugged from the charger before this test case is run. |
| </li> |
| </ol> |
