This allows you to substitute test implementations. When testing, we aren't trying to see if the automated DI works, we want to know the classes work independent of any external class, framework, or service.

Looks nice so far. That's nice but what about Mediators testing or anything else with [Inject]?

I've just started blogging on the topic of flex unit testing myself. The Flex community seems to be a way behind others in terms of knowledge and application of unit testing techniques.

Nice one Joel!

As the EventBroadcaster is a simple wrapper around the EventDispatcher, nulling and re-instantiating the broadcaster doesn't do much – ie, the EventDispatcher it wraps stays alive between tests, and the registered listeners will survive. I would recommend re-instantiating the EventDispatcher between tests. Something like:


private var service:FlickrImageService;
private var serviceDispatcher:EventDispatcher;

[Before]
public function setUp():void
{
serviceDispatcher = new EventDispatcher();
service = new FlickrImageService();
service.eventBroadcaster = new EventBroadcaster(serviceDispatcher);
}

[After]
public function tearDown():void
{
service.eventBroadcaster = null;
serviceDispatcher = null;
service = null;
}

Not sure if that will mess about with the async stuff – but I don't think so.
