Injecting services into AngularJS directive controller directly

Question

I understand how Angular dependency injection works with directives but wanted clarification on something. I have a dummy test directive as follows:

app.directiv

In this case, you're receiving the same service, so it likely doesn't matter too much. I personally prefer to keep them as localized as possible; if you don't need $filter in the link function or something like that, I'd just inject it into the controller.

In certain cases, this may also make it easier to mock dependencies during testing.
