Mockito：结合@Autowired 和@Mock

Question

我在 Spring Web 模型-视图-控制器 (MVC) 框架应用程序中使用 Mockito（Java 的开源测试框架，根据 MIT 许可证发布）进行了此 junit 测试

我有这个测试：

@RunWith(MockitoJUnitRunner.class)
public class DeviceCatalogueControllerTest {


    @InjectMocks
    private DeviceCatalogueController controller;

    @InjectMocks
    protected SessionHelper sessionHelper;

    @Mock
    private MessageSource messageSource;

    @Mock
    protected CataloqueService cataloqueService;

    @Autowired
    protected ApplicationDao applicationDao;

    @Before
    public void setUpTest() {
        request = new MockHttpServletRequest();
        response = new MockHttpServletResponse();
    }

    @Test
    public void testInitFormGet() throws Exception {

        System.out.println  ("SessionHelper sessionHelper --> " + sessionHelper);

        //controller.initFormGet(searchForm, localeParam, request, response, model, locale)
        controller.initFormGet(null, DEFAULT_LOCALE, request, response, null, new Locale(DEFAULT_LOCALE));
        }

但是当运行测试 applicationDao 为 null

Answer 1

您的测试 class 完全不知道 Spring。要在单元测试中使用 Spring，您必须使用正确的注释 @RunWith(SpringJUnit4ClassRunner.class) 而不是您现在使用的 @RunWith(MockitoJUnitRunner.class)。

然后在 @Before 方法中，您可以通过调用 MockitoAnnotations.initMocks(this);

来初始化 Mockito 模拟

您的测试 class 可以重新编码为：

@ContextConfiguration(locations = {"classpath:/application-context.xml"})
@RunWith(SpringJUnit4ClassRunner.class)
public class DeviceCatalogueControllerTest {


    @InjectMocks
    private DeviceCatalogueController controller;

    @InjectMocks
    protected SessionHelper sessionHelper;

    @Mock
    private MessageSource messageSource;

    @Mock
    protected CataloqueService cataloqueService;

    @Autowired
    protected ApplicationDao applicationDao;

    @Before
    public void setUpTest() {
        MockitoAnnotations.initMocks(this);
        request = new MockHttpServletRequest();
        response = new MockHttpServletResponse();
    }

    @Test
    public void testInitFormGet() throws Exception {

        System.out.println("SessionHelper sessionHelper --> " + sessionHelper);

        //controller.initFormGet(searchForm, localeParam, request, response, model, locale)
        controller.initFormGet(null, DEFAULT_LOCALE, request, response, null, new Locale(DEFAULT_LOCALE));
    }
}

注意：在 @ContextConfiguration(locations = {"classpath:/application-context.xml"})

中为您的 application-context.xml 使用正确的 xml 路径
