SpringBoot Junit bean autowire

Question

I am trying to write junit test for my service. I use spring-boot 1.5.1 in my project. Everything works fine, but when I try an autwire bean (created in AppConfig.class), it gives me a NullPointerException. I have tried almost everything.

This is my configuration class:

@Configuration 
public class AppConfig {

@Bean
public DozerBeanMapper mapper(){
    DozerBeanMapper mapper = new DozerBeanMapper();
    mapper.setCustomFieldMapper(new CustomMapper());
    return mapper;
 }
}

and my test class:

@SpringBootTest
public class LottoClientServiceImplTest {
@Mock
SoapServiceBindingStub soapServiceBindingStub;
@Mock
LottoClient lottoClient;
@InjectMocks
LottoClientServiceImpl lottoClientService;
@Autowired
DozerBeanMapper mapper;

@Before
public void setUp() throws Exception {
    initMocks(this);
    when(lottoClient.soapService()).thenReturn(soapServiceBindingStub);
}

@Test
public void getLastResults() throws Exception {

    RespLastWyniki expected = Fake.generateFakeLastWynikiResponse();
    when(lottoClient.soapService().getLastWyniki(anyString())).thenReturn(expected);

    LastResults actual = lottoClientService.getLastResults();

Can someone tell me what happened?

Error Log:

java.lang.NullPointerException
at pl.lotto.service.LottoClientServiceImpl.getLastResults(LottoClientServiceImpl.java:26)
at pl.lotto.service.LottoClientServiceImplTest.getLastResults(LottoClientServiceImplTest.java:45)

and this is my service:

@Service
public class LottoClientServiceImpl implements LottoClientServiceInterface {
@Autowired
LottoClient lottoClient;
@Autowired
DozerBeanMapper mapper;
@Override
public LastResults getLastResults() {
    try {
        RespLastWyniki wyniki = lottoClient.soapService().getLastWyniki(new Date().toString());
        LastResults result = mapper.map(wyniki, LastResults.class);
        return result;
    } catch (RemoteException e) {
        throw new GettingDataError();
    }
}

Of course, your dependency will be null, because @InjectMocksyou are creating a new instance, out of visibility of Spring, and therefore nothing will be automatically connected.

Spring Boot , beans mocks, . Spring .

, , .

• @Mock @MockBean
• @InjectMocks @Autowired

, SOAP ( , LottoClient for).

- .

@SpringBootTest
public class LottoClientServiceImplTest {

    @MockBean
    SoapServiceBindingStub soapServiceBindingStub;

    @Autowired
    LottoClientServiceImpl lottoClientService;

    @Test
    public void getLastResults() throws Exception {

        RespLastWyniki expected = Fake.generateFakeLastWynikiResponse();
        when(soapServiceBindingStub.getLastWyniki(anyString())).thenReturn(expected);

        LastResults actual = lottoClientService.getLastResults();
