Hello, Technically the Android Service should support injection by giving you some "Dependency Resolver/Container" so you can pass the resolver/container from the framework you are working with. But this is not the case, in fact, the Android Developer Training don't recommend the use of Dependency Injections frameworks ( http://developer.android.com/training/articles/memory.html#DependencyInjection ).
Here we are facing the same problem. I think you could use the Android Annotations injection ( https://github.com/excilys/androidannotations/wiki/Enhance-custom-classes), but I don't know how you could use it on unit testing because android annotations resolve the dependencies in compile time. Another suggestion is the old fashion "unit test constructor". I don't know if this works, but you could give a try: create a constructor that receives all your dependencies (but you still need the default without parameters, so that Android could start your service) and instead of the traditional ServiceTestCase, just do a new FooService with your dependencies and call your doSomeThing method.
