This test validates the various user interface event handlers. The test shows a target that can be used to generate the various kinds of mouse and keyboard events supported in SVG. Below the target, the list of events is shown with red markers next to each.

If the test passes, all the markers should have turned to green after the events have been triggered on the target. If any event has not triggered, its marker will remain red.

There are two reference images associated with this test case. The first illustrates the correct "start" or initial state of the rendered SVG file. The second illustrates the correct "finish" or final state of the rendered SVG, after the above-mentioned interaction, and if all tested events, have been successfully triggered. (Note. This harness does not yet provide access to both PNGs.)
