我正在尝试第一次使用PowerMockito模拟类构造函数，但是它不起作用。我当前的代码是：

public class Bar {
    public String getText() {
        return "Fail";
    }
}
public class Foo {
    public String getValue(){
        Bar bar= new Bar();
        return bar.getText();
    }
}
@RunWith(PowerMockRunner.class)
@PrepareForTest(Bar.class)
public class FooTest {
    private Foo foo;
    @Mock
    private Bar mockBar;
    @Before
    public void setUp() throws Exception {
        MockitoAnnotations.initMocks(this);
        PowerMockito.whenNew(Bar.class).withNoArguments().thenReturn(mockBar);
        foo= new Foo();
    }
    @Test
    public void testGetValue() throws Exception {
        when(mockBar.getText()).thenReturn("Success");
        assertEquals("Success",foo.getValue());
    }
}
