当我运行应用程序Butterknife绑定好，但在我的Robolectric 3.0测试中，我得到以下异常：

测试设置 

    @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);
}

碎片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();
    
}

请有人帮忙解决这个问题，因为我想一起使用butterknife和robolectric。

PowerMock经常与Robolectric发生冲突。当作者将其从测试中删除时，问题得以解决
