PowerMock + Robolectric + Dagger2

Activity activity;
@Mock
FileDownloaderManager fileDownloaderManager;

    @Rule
    public PowerMockRule rule = new PowerMockRule();

    @Before
    public void beforeTest() {

        // You intialise activity here
        activity = Robolectric.setupActivity(Activity.class);
    }

    @Test
    public void init_FileDownloaded() {

        // and use it here, the initialisation is out of scope for this
        ProgressTextView progressTextView = new ProgressTextView(activity);
    }

You need to change your program logic to allow for something like this:

Activity activity;
@Mock
FileDownloaderManager fileDownloaderManager;

    activity = Robolectric.setupActivity(Activity.class);

    @Rule
    public PowerMockRule rule = new PowerMockRule();

    @Before
    public void beforeTest() {

    }

    @Test
    public void init_FileDownloaded() {

        ProgressTextView progressTextView = new ProgressTextView(activity);
    }

Also

 ApplicationSIP.get().applicationComponent().inject(this);

I'm not sure what you are referring to as this

I cannot see where you are initialsing FileDownloaderManager in you classes, but it seems you are attempting to use the custom manager as the inbuilt android manager.

Caused by: java.lang.ClassCastException: Cannot cast com.tg.osip.tdclient.update_managers.FileDownloaderManager$$EnhancerByMockitoWithCGLIB$$a751cd05 to com.tg.osip.tdclient.update_managers.FileDownloaderManager
at java.lang.Class.cast(Class.java:3369)

I hope this helps to get you a little clearer.
