/**
* Simulate that an AJAX event has been fired. You add an AJAX event to a component by using:
*
* <pre>
* ...
* component.add(new AjaxEventBehavior(ClientEvent.DBLCLICK) {
* public void onEvent(AjaxRequestTarget) {
* // Do something.
* }
* });
* ...
* </pre>
*
* You can then test that the code inside onEvent actually does what it's supposed to, using the
* WicketTester:
*
* <pre>
* ...
* tester.executeAjaxEvent(component, ClientEvent.DBLCLICK);
*
* // Test that the code inside onEvent is correct.
* ...
* </pre>
*
* PLEASE NOTE! This method doesn't actually insert the component in the client DOM tree, using
* javascript.
*
* @param component The component which has the AjaxEventBehavior we wan't to test. If the
* component is null, the test will fail.
* @param event The event which we simulate is fired. If the event is null, the test will fail.
