示例1: checkIsClippingStackingContextAndContainer
static void checkIsClippingStackingContextAndContainer(LayoutBoxModelObject& obj)
{
EXPECT_TRUE(obj.canContainFixedPositionObjects());
EXPECT_TRUE(obj.hasClipRelatedProperty());
EXPECT_TRUE(obj.style()->containsPaint());
// TODO(leviw): Ideally, we wouldn't require a paint layer to handle the clipping
// and stacking performed by paint containment.
ASSERT(obj.layer());
PaintLayer* layer = obj.layer();
EXPECT_TRUE(layer->stackingNode() && layer->stackingNode()->isStackingContext());
