春天开机：使用@Configuration类

单元测试类我有这样的服务类：春天开机：使用@Configuration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())); 
    } 

}

和一个配置类是这样的：

@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; 
    } 

}

我试图单元测试像这样：

@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); 
    } 

}

然而，failes实例化storageProperties：

我该如何处理这个问题（我正在使用最新的Spring Boot）？

如果你真的想“单元”测试这个，我不认为你需要启动Spring的上下文。

@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); 
    } 

}

如果你确实要启动Spring上下文（“集成”测试），你需要有src/test/resources下storage.properties文件，就像你可能在src/main/resources。

啊，非常感谢！是的，我绝对想要把它作为一个单元测试来执行。我无法弄清楚如何正确地模拟一切。再次感谢！ – user3813234
