Как внедряешь зависимости в тесты

class UserServiceTest {
    private UserRepository mockRepo = Mockito.mock(UserRepository.class);
    private UserService userService = new UserService(mockRepo);
}

@ExtendWith(MockitoExtension.class)
class UserServiceTest {
    @Mock
    private UserRepository userRepo;
    
    @InjectMocks
    private UserService userService;
}

@SpringBootTest
class UserControllerTest {
    @MockBean
    private UserService userService;
}
