SimpleTest.waitForExplicitFinish();
/*
This file runs a series of type-agnostic tests to check the state of the mini DOM trees that represent various SVG 'list' attributes (including checking the "object identity" of the objects in those trees) in the face of various changes, both with and without the complication of SMIL animation being active.
For additional high level information on the tests that are run, see the comment for 'create_animate_elements' below.
To have the battery of generic tests run for a new list attribute, add an element with that attribute to the document, then add a JavaScript object literal to the following 'tests' array with the following properties:
target_element_id
The ID of the element that has the attribute that is to be tested.
attr_name
The name of the attribute that is to be tested.
prop_name
The name of the DOM property that corresponds to the attribute that is to
be tested. For some list types the SVGAnimatedXxxList interface is
inherited by the element interface rather than the element having a
property of that type, and in others the list type is not animatable so
there is no SVGAnimatedXxxList interface for that list type. In these
cases this property should be set to null.
bv_name
The name of the DOM base value property for the attribute that is to be
tested. This is usually 'baseVal', but not always. In the case of
SVGStringList, which is not animatable, this is the name of the
SVGStringList property.
av_name
The name of the DOM anim value property for the attribute that is to be
tested. This is usually 'animVal' but not always. In the case of
SVGStringList, which is not animatable, this should be set to null.
el_type
The name of the SVGXxxElement interface on which the property corresponding
to the attribute being tested is defined.
prop_type
The name of the SVGAnimatedXxxList interface (e.g. SVGAnimatedLengthList),
if it exists, and if the element has a property is of this type (as
opposed to the element interface inheriting it).
list_type
The name of the SVGXxxList interface implemented by the baseVal and
animVal objects.
item_type
The name of the SVGXxx interface implemented by the list items.
attr_val_3a:
attr_val_3b:
Two attribute values containing three different items.
attr_val_4
An attribute value containing four items.
attr_val_5a:
attr_val_5b:
Two attribute values containing five different items.
attr_val_5b_firstItem_x3_constructor:
Function to construct a list-item that should match the first item in a
SVGXxxList after three repeats of a cumulative animation to attr_val_5b.
This function takes t.item_constructor as its only argument.
item_constructor:
Function to create a dummy list item.
item_is:
Function to compare two list items for equality, like "is()". If this
property is omitted, it is assumed that we can just compare
"item.value" (which is the case for most list types).

This function returns a DocumentFragment with three 'animate' element children. The duration of the three animations is as follows:
animation 1: | *-----------*-----------*-----------*
animation 2: | *--*
animation 3: | *--*
|___________________________________________> time (s)
| | | | | | | | | | | | | | |
0 1 2 3 4 5 6 7 8 9 10 11 12 13 14
The first animation repeats once so that we can test state on a repeat animation.
The second animation overrides the first animation for a short time, and has fewer list items than the first animation. This allows us to test object identity and other state on and after an overriding animation. Specifically, it allows us to check whether animVal list items are kept or discarded after the end of an overriding animation that has fewer items.
The third animation has additive="sum", with fewer items than the lower priority animation 1, allowing us to test object identity and other state in that scenario. TODO: some type aware tests to check whether the composite fails or works?
At t=0s and t=1s we test the effect of an attribute value changes in the absence and presence of SMIL animation respectively.
At t=10s we programmatically remove the fill="freeze" from animation 1.
