This test checks the use of SVGAnimatedEnumeration within SVGFilterElement On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE". Check initial 'filterUnits' value PASS filterElement.filterUnits.toString() is "[object SVGAnimatedEnumeration]" PASS typeof(filterElement.filterUnits.baseVal) is "number" PASS filterElement.filterUnits.baseVal is SVGUnitTypes.SVG_UNIT_TYPE_USERSPACEONUSE Switch to 'objectBoundingBox' PASS filterElement.filterUnits.baseVal = SVGUnitTypes.SVG_UNIT_TYPE_OBJECTBOUNDINGBOX is SVGUnitTypes.SVG_UNIT_TYPE_OBJECTBOUNDINGBOX PASS filterElement.filterUnits.baseVal is SVGUnitTypes.SVG_UNIT_TYPE_OBJECTBOUNDINGBOX PASS filterElement.getAttribute('filterUnits') is "objectBoundingBox" Try setting invalid values PASS filterElement.filterUnits.baseVal = 3 threw exception TypeError: Type error.
