Unit testing Spring boot application-test.properties未在测试组件内初始化

我正在为一个从application.properties获取值的组件编写一个测试

在测试本身中，从application-test.properties中正确提取值。 我使用了@TestPropertySourcelocations=classpath:application-test.properties

然而，在被测试的类中，这些值没有被提取出来，并且是空的

测试：

@RunWith(SpringJUnit4ClassRunner.class)
@TestPropertySource(locations = "classpath:application-test.properties")
public class ArtifactAssociationHandlerTest {

private InputStream inputStreamMock;
private ArtifactEntity artifactMock;
private ArtifactDeliveriesRequestDto requestDto;
@Value("${sdc.be.endpoint}")
private String sdcBeEndpoint;
@Value("${sdc.be.protocol}")
private String sdcBeProtocol;
@Value("${sdc.be.external.user}")
private String sdcUser;
@Value("${sdc.be.external.password}")
private String sdcPassword;

@Mock
private RestTemplate restClientMock;

@Mock
private RestTemplateBuilder builder;

@InjectMocks
private ArtifactAssociationService associationService;

@Before
public void setUp() throws IOException {
    inputStreamMock = IOUtils.toInputStream("some test data for my input stream", "UTF-8");
    artifactMock = new ArtifactEntity(FILE_NAME, inputStreamMock);
    requestDto = new ArtifactDeliveriesRequestDto("POST",END_POINT);
    MockitoAnnotations.initMocks(this);
    associationService = Mockito.spy(new ArtifactAssociationService(builder));
    associationService.setRestClient(restClientMock);
}

被测部件：

@Component("ArtifactAssociationHandler")
public class ArtifactAssociationService {

@Value("${sdc.be.endpoint}")
private String sdcBeEndpoint;
@Value("${sdc.be.protocol}")
private String sdcBeProtocol;
@Value("${sdc.be.external.user}")
private String sdcUser;
@Value("${sdc.be.external.password}")
private String sdcPassword;

private RestTemplate restClient;

@Autowired
public ArtifactAssociationService(RestTemplateBuilder builder) {
    this.restClient = builder.build();
}

 void setRestClient(RestTemplate restClient){
    this.restClient = restClient;
}

如何使用application-test.properties正确地测试此问题

您的安装方法正在创建ArtifactAssociationService的实例。这意味着它不是Springbean，因此没有执行任何依赖项注入。这包括注入到用@Value注释的字段中

---

如果您希望@Value注释的字段被注入它们的值，您必须使您的ArtifactAssociationService实例成为一个bean，例如，通过在@Configuration类中使用@bean方法创建它。

我最初不是在setup方法中创建实例的，而是为了将restCilent设置为mock实例。即使删除了初始化，仍然是相同的值为空：@Spy InjectMocks private ArtifactAssociationService associationService；在public void安装程序抛出IOException{MockitoAnnotations.initMocksthis；//associationService=Mockito.spynew ArtifactAssociationServicebuilder；associationService.SetRestClientRestClientClientMock；}之前，很难读取注释中的代码，但看起来您仍在自己创建ArtifactAssociationService:new ArtifactAssociationService Builder。很抱歉，我无法将其添加为代码块。。这一行被注释掉了
