@RunWith(MockitoJUnitRunner.class)

    private EmailService emailService;

    @Mock
    private JavaMailSender javaMailSender;

    @Mock
    private MongoTemplate mongoTemplate;

    @Mock
    private FileStorageProperties fileStorageProperties;

    @Mock
    private Path fileStorageLocation;
}
