This tests trait access methods on the TraitAccess interface
for the 'begin' trait. Each trait getter and setter method is called on
each applicable SVG Tiny 1.2 element.
The test is passed if, five seconds after the document begins:
the rectangle is blue,
there is a blue circle to the right of the rectangle whose
diameter is the same as the height of the rectangle,
an animation showing rotating rectangles to the right of the circle begins,
a video showing a dog to the right of the animation begins (if 3gp video is supported), and
an audio clip begins playing (if wav audio is supported).
Also, there must be no text displayed inside the rounded green rectangle.
