    <h1>Description</h1>
    <p>
      This test validates that all of the navigator.battery attributes exist and are set to correct values, when the battery is charging.
    </p>
    <h2>Preconditions</h2>
    <ol>
      <li>
        The device is plugged in to the charger before this test is run.
      </li>
      <li>
        The battery must neither be empty or full, nor reach empty or full capacity during the test.
      </li>
    </ol>
