Hi, I have a requirement to create a component to extend from teaser. I'm writing the junit for my custom component.

How to mock teaser java class object in my custom component where i extended the teaser core component.

Thanks in advance

Hi, Thanks for the reply.

I have changed the mockito version, using 5.3.1 now not getting error. But Impl code is not getting coverage. this code runs alone.

@aravinds,

Not sure how you check this or run this code. See my previous screenshot I set a debugger point on the main Model Java class. That means it actually calls the real method.

Check this again, perfectly fine and shows the coverage percentage on my IDE.
This is not only for this project. I just copy the process from my client project and this is how coverage is made up.
Hope you got my point.

Hello @aravinds ,

I tried many ways to write unit-test but nothing works for me. Especially the @Self annotation

@Self
private Teaser coreTeaser;

Then I conclude by this way to write the unit test

import static org.mockito.Mockito.when;
import org.mockito.Mockito;

@ExtendWith({AemContextExtension.class, MockitoExtension.class})
public class TeaserExtdImplTest {
    private final AemContext aemContext = new AemContext(ResourceResolverType.JCR_MOCK);
    private final TeaserExtd teaserExtd = Mockito.spy(TeaserExtdImpl.class);

    @Mock
    private Teaser coreTeaser;

    @BeforeEach
    void init() throws NoSuchFieldException {
        PrivateAccessor.setField(teaserExtd, "coreTeaser", coreTeaser);
    }

    @Test
    public void idTest() {
        when(coreTeaser.getId()).thenReturn("1234");
        assertNotNull(coreTeaser.getId());
    }
}

You may try this way. This might help you.
