  19 <h2>Description</h2>
  20 <p>
  21   This test validates that all of the BatteryManager attributes exist and
  22   are set to correct values, with corresponding events fired,
  23   when the charger is plugged in.
  24 </p>
  25
  26 <h2>Preconditions</h2>
  27 <ol>
  28   <li>
  29     The device is unplugged from the charger before this test is run.
  30   </li>
  31   <li>
  32     The battery must not be full or reach full capacity before the time the test is run.
  33   </li>
  34 </ol>
  35
  36 <div id="note">
  37   <ol>
  38     <li>
  39       Plug in the charger and wait for all the tests to complete.
  40     </li>
  41     <li>
  42       The tests may take long time since the definition of how
  43       often the chargingtimechange, dischargingtimechange, and levelchange
  44       events are fired is left to the implementation.
