java - 如何模拟CrudRepository调用？

我正在尝试在Spring MVC应用程序上进行简单的 Controller 测试

我有这个测试类

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {TestContext.class, WebAppConfig.class})
@WebAppConfiguration
public class NotificacaoControllerTest {

    private MockMvc mockMvc;

    @Autowired
    private NotificacaoRepository notificacaoRepositoryMock;

    @Autowired
    private WebApplicationContext webApplicationContext;

    @Before
    public void setUp() {
        //We have to reset our mock between tests because the mock objects
        //are managed by the Spring container. If we would not reset them,
        //stubbing and verified behavior would "leak" from one test to another.
        Mockito.reset(notificacaoRepositoryMock);

        mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
    }

    @Test
    public void add_NewTodoEntry_ShouldAddTodoEntryAndRenderViewTodoEntryView() throws Exception {
        Notificacao added = new Notificacao(123,"resource","topic", "received", "sent");

        when(NotificacaoRepository.save( added )).thenReturn(added);

我的TestContext类有这个bean

@Bean
public NotificacaoRepository todoService() {
    return Mockito.mock(NotificacaoRepository.class);
}

而我的仓库就是

public interface NotificacaoRepository extends CrudRepository<Notificacao, Long> {
}

但它甚至都没有编译，我不断得到“无法在最后一行“上从类型CrudRepository ”对非静态方法save(Notificacao)进行静态引用when(NotificacaoRepository.save(added)) ”

我在此链接http://www.petrikainulainen.net/programming/spring-framework/unit-testing-of-spring-mvc-controllers-normal-controllers/的示例中看到了这种用法，但是他在那里使用了服务类，这与使用CrudRepository并不完全一样。

我试图找到一个如何测试CrudRepository实现的示例，但是没有找到一个示例，因此我认为这应该像其他模拟一样简单

最佳答案

由于save方法不是静态的，因此您必须进行更改

  when(NotificacaoRepository.save( added )).thenReturn(added);

要将对象用作:

when(notificacaoRepositoryMock.save( added )).thenReturn(added);
