### Question:
KmlTrack extends KmlLineString { public ArrayList<Long> getTimestamps() { return mTimestamps; } KmlTrack(ArrayList<LatLng> coordinates, ArrayList<Double> altitudes, ArrayList<Long> timestamps, HashMap<String, String> properties); ArrayList<Long> getTimestamps(); HashMap<String, String> getProperties();  }### Answer:
@Test public void testTimestamps() { KmlTrack kmlTrack = createSimpleTrack(); assertNotNull(kmlTrack); assertNotNull(kmlTrack.getTimestamps()); assertEquals(kmlTrack.getTimestamps().size(), 3); assertEquals(kmlTrack.getTimestamps().get(0), Long.valueOf(1000L)); assertEquals(kmlTrack.getTimestamps().get(1), Long.valueOf(2000L)); assertEquals(kmlTrack.getTimestamps().get(2), Long.valueOf(3000L)); }
