The 'Binder' seems not friendly for unit testing

[luziqin]

There a lot of binding and app logic inside the binder part will make it hard for unit testing.Did you ever consider this problem?

Yes, although what makes it hard to unit test is not that there is a lot of binding and app logic in there, but the fact that you have to mock the inputs (service). However, that is a common problem when testing a component that has a dependency on some other component.

As for the side effects on the view controller, those can easily be check by inspecting the instance.

I would suggest the following approach for testing:

1) To test business logic: write unit tests against the services 2) To test app logic: write UI tests against the app
