spring boot：使用@Configuration类的单元测试类

时间：2016-12-15 19:48:40

标签： java unit-testing spring-boot

我有这样的服务类：

@Service
public class FileSystemStorageService implements StorageService {

    private final StorageProperties storageProperties;

    @Autowired
    public FileSystemStorageService(final StorageProperties storageProperties) {
        this.storageProperties = storageProperties;
    }

    @Override
    public void store(final MultipartFile file) {
        try {
            if (!file.getContentType().equals("application/x-zip-compressed")) {
                throw new StorageInvalidFileTypeException("Wrong filetype");
            }
            Files.copy(file.getInputStream(), storageProperties.getUploadDir()
                    .resolve(file.getOriginalFilename()));
    }

}

这样的Configuration类：

@Configuration
@ConfigurationProperties("storage")
public class StorageProperties {

    private final Path uploadDir = Paths
            .get(System.getProperty("jboss.server.data.dir"))
            .resolve("uploads");

    public Path getUploadDir() {
        return uploadDir;
    }

}

我正试图对它进行单元测试：

@RunWith(SpringRunner.class)
@SpringBootTest(classes = MySpringAppApplication.class)
public class FileUploadTests {

    @Autowired
    private StorageService storageService;


    @Test(expected = StorageInvalidFileTypeException.class)
    public void shouldCheckTheFileType() {
        final Path fileName = Paths.get("MyTestUpload");
        final byte[] content = new String("SomeContent").getBytes();
        final MockMultipartFile mockMultipartFile = new MockMultipartFile(
                "content", fileName.toString(), "text/plain", content);

        storageService.store(mockMultipartFile);
    }

}

但是，实例化storageProperties很麻烦：

我该如何处理（我使用的是最新的Spring Boot）？

1 个答案:

答案 0 :(得分：1)

如果你真的想“单元”测试这个，我认为你不需要启动Spring上下文。

@RunWith(MockitoJUnitRunner.class)
public class FileUploadTests {

    @InjectMocks
    private StorageService storageService;

    @Mock
    private StorageProperties storageProperties;

    @Test(expected = StorageInvalidFileTypeException.class)
    public void shouldCheckTheFileType() {
        Mockito.when(storageProperties.getUploadDir()).thenReturn(Paths
        .get(System.getProperty("jboss.server.data.dir"))
        .resolve("uploads"));

        final Path fileName = Paths.get("MyTestUpload");
        final byte[] content = new String("SomeContent").getBytes();
        final MockMultipartFile mockMultipartFile = new MockMultipartFile(
                "content", fileName.toString(), "text/plain", content);

        storageService.store(mockMultipartFile);
    }

}

如果您确实想要启动Spring上下文（“集成”测试），则需要在storage.properties下设置src/test/resources文件，就像您在src/main/resources中所拥有的那样
