Mockolate: dispatch binding events?

Question

Is it possible to ask Mockolate to dispatch binding events?

For example, given this class:

class Person {
    [Bindable]
    public var name:String;
}

I'd like the mock:

var mockPerson:Person = nice(Person);

To dispatch a propertyChangeEvent when the name field is change.

As you mentioned Binding events are instances of PropertyChangeEvent, just create an instance using PropertyChangeEvent.createUpdateEvent() and use that with .dispatches().

Like so:

mock(person).setter("name").arg(anything())
    .dispatches(PropertyChangeEvent.createUpdateEvent(person, "name", oldValue, newValue));

Note however that the oldValue and newValue will need to be supplied.

I see merit in making a shortcut for this scenario seeing as binding is heavily used. The only tricky part is keeping the previous value.

If you wanted to tackle implementing this yourself I suggest looking at the Answer and Decorator classes and subclasses.
