mockito: The class [X] not prepared for test
After migrating my JAVA EE app. (Spring Web model-view-controller (MVC) framework) from Ant to Maven I have some errors executing the Junit test that before the migration were working fine
org.powermock.api.mockito.ClassNotPreparedException:
The class org.springframework.web.util.WebUtils not prepared for test.
To prepare this class, add class to the '@PrepareForTest' annotation.
In case if you don't use this annotation, add the annotation on class or method level.

Answer
Try @RunWith(PowerMockRunner.class) instead of @RunWith(MockitoJUnitRunner.class)
