I am trying to create a Mock instance for spring Component class. Below is the spring component class.

@Component
public class MyComponentMapperClass {

@Value("${some.property}")
private String var;

public void someMapperMethod() { // }

This is my test class setup where I am trying to mock the above component class.

@RunWith(PowerMockRunner.class)
@PrepareForTest({MyDAOImpl.class})
public class MyDAOImplTest {

@Mock MyComponentMapperClass myComponentMapperClass;

}

While debugging, I see that Intellij highlights a mock object as "Mock Object of XYZClass", but for the mock I created above it doesn't happen like that. In addition I have tried:

MyComponentMapperClass myComponentMapperClass =  Mockito.mock(MyComponentMapperClass.class)

but still mock object is not created. This seems to be very straight-forward, but I haven't figured it out yet.

here is an answer from https://stackoverflow.com/users/2847174/ren%c3%a9-scheibe Mock Spring Component, which suggests to do the same, but is not working for me. Any help is appreciated. Thanks!

Use @InjectMocks – Thomson Ignesious Mar 29 '23 at 05:15
@InjectMocks would create an instance of the class and inject mocks to this instance, but what I need is a mock object. – Abhinash Jha Mar 29 '23 at 06:29
Which mock maker are you using? – Lesiak Mar 29 '23 at 08:31
I edited the answer. But, I didn't find an import for @Mock from Powermock. – Abhinash Jha Mar 29 '23 at 16:57
Please add MyComponentMapperClass to the PrepareForTest and use PowerMockito.mock(MyComponentMapperClass.class) to create a mock. Instead of Mock annotation. – Mar-Z Mar 29 '23 at 17:59
