ChallengeServiceTest failure

[Frank-Xiao2002]

Using mock at this step in ChallengeServiceTest.java is not appropriate since it will return null after running JPA repo methods like save etc. It should use @SpringBootTest and @Autowired to inject beans to test the service layer.

@SpringBootTest
public class ChallengeServiceTest {

    private ChallengeService challengeService;
//    @Mock
    @Autowired
    private UserRepository userRepository;

//    @Mock
    @Autowired
    private ChallengeAttemptRepository attemptRepository;

......
}
