This test checks the SVGAnimatedNumber API - utilizing the surfaceScale property of SVGFESpecularLightingElement

On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".


Check initial surfaceScale value
PASS feSpecularLightingElement.surfaceScale.toString() is "[object SVGAnimatedNumber]"
PASS typeof(feSpecularLightingElement.surfaceScale.baseVal) is "number"
PASS feSpecularLightingElement.surfaceScale.baseVal is 1

Check that integers are static, caching value in a local variable and modifying it, should have no effect
PASS numRef is 100
PASS feSpecularLightingElement.surfaceScale.baseVal is 1

Check assigning various valid and invalid values
PASS feSpecularLightingElement.surfaceScale.baseVal = -1 is -1
PASS feSpecularLightingElement.surfaceScale.baseVal = 300 is 300
PASS feSpecularLightingElement.surfaceScale.baseVal = 'aString' is 'aString'
PASS feSpecularLightingElement.surfaceScale.baseVal is NaN
PASS feSpecularLightingElement.surfaceScale.baseVal = 0 is 0
PASS feSpecularLightingElement.surfaceScale.baseVal = feSpecularLightingElement is feSpecularLightingElement
PASS feSpecularLightingElement.surfaceScale.baseVal is NaN
PASS feSpecularLightingElement.surfaceScale.baseVal = 300 is 300

Check that the surfaceScale value remained 300
PASS feSpecularLightingElement.surfaceScale.baseVal is 300
PASS successfullyParsed is true
