Butterknife unable to bind in Robolectric test - robolectric

Question

When I run the app Butterknife binds ok, but in my Robolectric 3.0 test I'm getting the following exception:
java.lang.RuntimeException: Unable to bind views for com.elt.passsystem.fragment.residential.task.TaskInstanceGeneralFragment

The Test setup
#Before
public void setup() throws Exception {
Injector.getInstance().setComponent(
DaggerTestComponent.builder()
.mockGlobalConfigsModule(new MockGlobalConfigsModule(true))
.mockDataAccessModule(new MockDataAccessModule(true))
.jobManagerModule(new JobManagerModule(RuntimeEnvironment.application))
.build()
);
PowerMockito.mockStatic(LogCustom.class);
PowerMockito.doNothing().when(LogCustom.class, "v", Mockito.anyString(), Mockito.anyString());
fragment = new TaskInstanceGeneralFragment();
SupportFragmentTestUtil.startFragment(fragment, EpisodeOfCareDetailActivity.class);
completeRadioGroup = fragment.getView().findViewById(R.id.radio_group_complete);
reasonLinearLayout = fragment.getView().findViewById(R.id.linear_layout_reason);
}
The Fragment onCreateView
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
super.onCreateView(inflater, container, savedInstanceState);

View root = inflater.inflate(R.layout.fragment_residential_activity_general, null, false);
try {
ButterKnife.bind(this, root);
} catch (Exception e) {
e.printStackTrace();
}
Please can someone help to fathom this out as I'd like to use butterknife and robolectric together.

PowerMock is quite often conflicting with Robolectric. The issue is resolved as author removed it from tests
