Java – mockito’s spy object in spring

When I try to snoop on objects in unit tests,

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:spring/applicationContext.xml" })
public class BookingSuperManTest {
    BookInfoParams bookInfoParams; 
    HttpAttributeParams httpAttributeParams;
    AbstractRequester requester;
    public void beforeStarttest(){
        bookInfoParams = Mockito.spy(new BookInfoParams());
        httpAttributeParams = Mockito.spy(new HttpAttributeParams());
    }
    @Test
    public void step1GoToHomePage() throws BookingException{
        beforeStarttest();

        requester = new Step1HomePage(bookInfoParams,httpAttributeParams);
        requester.executeRequest();

        Assert.assertNotNull(httpAttributeParams.getResponseGetRequest());
    }
}

I got an exception when assigning bookinfoparams spy to the link:

Maybe the version is incompatible or what did I miss?

Solution

It may be a dependency problem Powermock API mockito is available in mockito core version 1.10 There are compile time dependencies on version 19, but you also defined a dependency on version 2.0 44 beta dependency This may be a classpath problem Try to delete version 2.0 Explicit dependencies of 44 beta
