如何在单元测试中强制spring boot设置autowired字段

Question

我正在开发一个spring boot应用程序。我试着开发了一些单元测试。单元测试必须在不启动容器中的应用程序的情况下运行，必须是如此快，可以在不需要大量时间的情况下运行。假设我有一个类名applicationservice，如下所示：

@Service
public class ApplicationService {

     @Autowired
     private ApplicationRepository applicationRepository;


     @Autowired
     private final PasswordEncoder passwordEncoder;

     ///............
}

和以下测试：

@RunWith(SpringRunner.class)
@TestExecutionListeners(MockitoTestExecutionListener.class)
@ContextConfiguration
public class CreateApplicationTest {

    @Autowired
    @InjectMocks
    ApplicationService applicationService;

    @Mock
    private ApplicationRepository applicationRepository;

    @Before
    public void init() {
        MockitoAnnotations.initMocks(this);
    }

    @Test
    public void createApplication() {
        CreateApplicationDTO dto = new CreateApplicationDTO("some info");
        given(this.applicationService.createApplication(dto)).willReturn(null);
        ApplicationResultDTO application = applicationService.createApplication(dto);
        assertThat(application, is(someValue));
    }
}

将PasswordEncoder添加到带注释的@spy@AutoWired测试类中，以便在模拟的ApplicationService中使用

@Spy
@Autowired
private  PasswordEncoder passwordEncoder;
