Question

我正在为从application.properties中获取值的组件编写测试。

在测试本身中，可以从application-test.properies中正确获取值。我用@TestPropertySource（locations =“ classpath：application-test.properties”）

但是在测试的类中，值不会被获取并且为空。

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);
}

Tested组件：

@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进行正确测试？

Answer 1

您的setup方法正在创建ArtifactAssociationService的实例。这意味着它不是Spring bean，因此不执行任何依赖注入。这包括注入到用@Value注释的字段中。

如果您希望注入带有@Value的字段，则必须使ArtifactAssociationService实例成为bean，例如，通过在其中使用@Bean方法创建它@Configuration类。

Spring Boot application-test.properties未在测试的组件内初始化
