How to click a layout when testing?

I saw that the recently released Vaadin 6.8.0 had added click to the button class, which is great for testing and will be quite useful for me.

In the same vein, I have a clickable layout and would like to test that when I click it, the correct behavior occurs. Lacking something as convenient as Button’s click method, is there any easy way in which I can do this, and if so, what would such a solution look like?

Let me know and best regards,
