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

Thanks in advance

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.

Mockito cannot mock this class: interface com.adobe.cq.wcm.core.components.models.Teaser.

Not sure why you get this problem. Please check this out. I just pushed a code for the Carousel component. https://github.com/Sady-Rifat/my-project/commit/53adef48530751372af147a25527921b3dddc5f2 

Maybe you have other issues. This repo might help you for understanding.

Maybe the issue is related to your Java version. Here I am using JDK 11.

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.
