Mockito code during @Before annoted method solution

i'm new on using Mockito framework (and Behavior/Test Driven Development) and using to help me code some things;

I´m coding my own Java library for xml to create graphic things and i tried first verify some behaviours: (MockitoAnnotations.initMocks(Class) is used in BaseTestClass):

public class GeneralXml extends BaseTestClass {

    private static final String TAG = "General XML";
    @Mock(name="xml") private XmlGraphics mockXML;

    @Before
    public void s开发者_如何学编程etUp() throws Exception{ 

        //stub method parseDimension
        when(mockXML.parseDimension(anyString()))
            .thenReturn(500);

        // stub method parsePosition: 500 X 500 X 500 is an
        // arbitrary dimension of window
        when(mockXML.parsePosition(anyString()))
            .thenReturn(
                new Random().nextFloat() * mockXML.parseDimension(Xml.WIDTH),
                new Random().nextFloat() * mockXML.parseDimension(Xml.HEIGHT),
                new Random().nextFloat() * mockXML.parseDimension(Xml.DEPHT));

        // Now Colors must have betwwen 0 and 255
        // (RGB color)
        when(mockXML.parseColorComponent(anyString()))
            .thenReturn(
                new Random().nextInt(256),    
                new Random().nextInt(256),    
                new Random().nextInt(256));    

    }

But I receive error in all subsequent verifications, like:

@Test
public void mockPosition() {
    Log.d(TAG, "mock", "x = "+mockXML.parsePosition(Xml.X));
    Log.d(TAG, "mock", "y = "+mockXML.parsePosition(Xml.Y));
    Log.d(TAG, "mock", "z = "+mockXML.parsePosition(Xml.Z));

    verify(mockXML, times(3)).parsePosition(anyString());
}    

I think that my error is in:

 when(mockXML.parsePosition(anyString()))    
        .thenReturn(    
            new Random().nextFloat() * mockXML.parseDimension(Xml.WIDTH),
            new Random().nextFloat() * mockXML.parseDimension(Xml.HEIGHT),
            new Random().nextFloat() * mockXML.parseDimension(Xml.DEPHT));

This is not a valid code? or I misunderstanding something? Thanks for any help

Try adding this as the first line in your setUp() function:

    MockitoAnnotations.initMocks(this);
