void tst_PositionPlugin::getUpdates()
{
    QGeoPositionInfoSource *src = QGeoPositionInfoSource::createSource("test.source", 0);
    src->setUpdateInterval(1000);

    QSignalSpy spy(src, SIGNAL(positionUpdated(QGeoPositionInfo)));
    src->startUpdates();
    QTest::qWait(1500);
    QCOMPARE(spy.count(), 1);
    QCOMPARE(spy[0].size(), 1);

    QGeoPositionInfo info = qvariant_cast<QGeoPositionInfo>(spy[0][0]);
    QCOMPARE(info.coordinate().latitude(), 0.1);
