You can also try:

view.btnAddField.fireEvent(new ClickEvent() { } );

(It's a little hack, because com.google.gwt.event.dom.client.ClickEvent has protected constructor.)

or

DomEvent.fireNativeEvent(Document.get().createClickEvent(0, 0, 0, 0, 0,
            false, false, false, false), view.btnAddField);

Then, in both cases, there's no need to create separate classes and break encapsulation for handlers in order to test click events.

I solve that problem by using this code

btnAddField.fireEvent(new ButtonClickEvent ())

private class ButtonClickEvent extends ClickEvent{
        /*To call click() function for Programmatic equivalent of the user clicking the button.*/
    }

It is working fine now.
