<h2>Description</h2>
<p>
This test validates that all of the BatteryManager attributes exist and
are set to correct values, with corresponding events fired,
when the charger is plugged in.
</p>
<h2>Preconditions</h2>
<ol>
<li>
The device is unplugged from the charger before this test is run.
</li>
<li>
The battery must not be full or reach full capacity before the time the test is run.
</li>
</ol>
<div id="note">
<ol>
<li>
Plug in the charger and wait for all the tests to complete.
</li>
<li>
The tests may take long time since the definition of how
often the chargingtimechange, dischargingtimechange, and levelchange
events are fired is left to the implementation.
</li>
</ol>
</div>
<div id="log"></div>
