Spring boot junit test - ClassNotFoundException

我有一个 spring 启动应用程序运行没有问题 . 我想编写一些单元测试并遇到以下异常：

我想要的只是测试@Service注释bean并正确连接它 .

@RunWith(SpringRunner.class)
@SpringBootTest
public class ImageResizeTest {

    @Autowired
    private ImageService imageService;

    @Test
    public void imageResizeTest() throws IOException {
        BufferedImage image = ImageIO.read(new File("E:\\tmp\\original.jpg"));
        imageService.storeComicCover(image, "mytest.jpg");
    }
}

@Service
public class ImageService {
    private static final Logger LOG = LoggerFactory.getLogger(ImageService.class);
    public static final String FORMAT_NAME = "jpg";

    @Value("${image.norm.resize.height}")
    private int normalResizeHeight;
    @Value("${image.norm.resize.width}")
    private int normalResizeWidth;

    @Value("${image.thumb.resize.height}")
    private int thumbResizeHeight;
    @Value("${image.thumb.resize.width}")
    private int thumbResizeWidth;

    @Value("${image.mini.resize.height}")
    private int miniResizeHeight;
    @Value("${image.mini.resize.width}")
    private int miniResizeWidth;

    @Value("${image.comics.original.path}")
    private String originalComicPath;
    @Value("${image.stories.original.path}")
    private String originalStoriesPath;
    @Value("${image.characters.original.path}")
    private String originalCharactersPath;

    @Value("${image.comic.resized.path}")
    private String resizeComicPath;
    @Value("${image.stories.resized.path}")
    private String resizeStoriesPath;
    @Value("${image.characters.resized.path}")
    private String resizeCharactersPath;

    public ImageAttributes storeComicCover(BufferedImage originalImage, String originalImageName) {

我试图在maven中添加缺少的lib和测试范围，但这没有任何效果 .
