self.assertEqual(rect.xMinimum(), 0.0)
self.assertEqual(rect.yMinimum(), 1.0)
self.assertEqual(rect.xMaximum(), 20.0)
self.assertEqual(rect.yMaximum(), 10.0)
self.assertEqual(rect.crs().authid(), 'EPSG:3111')
rect.setCrs(QgsCoordinateReferenceSystem('epsg:28356'))
self.assertEqual(rect.crs().authid(), 'EPSG:28356')
# in variant
v = QVariant(QgsReferencedRectangle(QgsRectangle(1.0, 2.0, 3.0, 4.0), QgsCoordinateReferenceSystem('epsg:3111')))
