Exception when stubbing static: GloballyConfiguredAnswer cannot be cast to org.mockito.ReturnValues

GoogleCodeExporter commented 9 years ago

What steps will reproduce the problem?
1. Attempting to stub a getInstance() method of a factory to return a stub.
2. Using Junit 4.4, execute the test.
3. Issue starts from: PowerMockito.mockStatic(InvokerFactory.class); 

What is the expected output? What do you see instead?
I expect a mock to created and usuable in the later calls:

        Mockito.when(InvokerFactory.getInvoker()).thenReturn("1"); 
        InvokerFactory.getInvoker();

What version of the product are you using? On what operating system?

 - Windows XP (SP1)
 - PowerMock 1.2.5.
 - Junit 4.4
 - Eclipse 3.4.2.

Please provide any additional information below.

====

public class InvokerFactory
{
    private InvokerFactory(){}

    public static String getInvoker()
    {
        return "ret";
    }
}

====

@RunWith( PowerMockRunner.class)
@PrepareForTest({InvokerFactory.class})
public class FactorTest extends TestCase
{
    public void testd() throws ServiceException
    {     
        PowerMockito.mockStatic(InvokerFactory.class); // <-- Error
        Mockito.when(InvokerFactory.getInvoker()).thenReturn("1"); 
        InvokerFactory.getInvoker();
    }
}

Would help if I added the stack trace:

Are you using Mockito 1.8? It's not yet supported. We're working to upgrading 
our
PowerMock to work with Mockito 1.8 but right now it only works with 1.7.
