【问题描述】：

我试图为使用 Spring Data Rest 构建的 REST API 设置单元测试。我有一个这样的存储库：

@RepositoryRestResource
public interface BeerRepository extends JpaRepository<Beer, Long> 

我的测试如下所示：

public class BeerRestTest extends AbstractRestTest 

    @Autowired
    @Qualifier("beerRepositoryMock")
    protected BeerRepository beerRepositoryMock;

    @Before
    public void setUp() 
        super.setUp();
        Mockito.reset(beerRepositoryMock);
    

    @Test
    public void testGetBeer() throws Exception 
        Beer beer = new Beer();
        beer.setId(1L);
        beer.setName("Duff");

        when(beerRepositoryMock.findOne(1L)).thenReturn(beer);

        mockMvc.perform(get("/api/beers/id", 1L))
                .andDo(print())
                .andExpect(status().isOk());

        verify(beerRepositoryMock, times(1)).findOne(1L);
        verifyNoMoreInteractions(beerRepositoryMock);
    

spring data rest 配置如下：

public class RestConfig extends RepositoryRestMvcConfiguration 

    @Bean
    public RepositoryRestConfigurer repositoryRestConfigurer() 
        return new RepositoryRestConfigurerAdapter() 
            @Override
            public void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) 
                config.setBasePath("/api");
            
        ;
    

最后是日志

编辑：beerRepositoryMock

@Bean(name = "beerRepositoryMock")
public BeerRepository beerRepositoryMock() 
    return Mockito.mock(BeerRepository.class);

谢谢

【问题讨论】：

您能否展示一下您是如何创建 bean beerRepositoryMock 的。

@MathiasDpunkt 完成 :)

【参考方案1】：

查看 spring data rest 查找存储库的方式，我看不到让 spring data rest 使用您的模拟存储库的方法。

通过您的配置，您最终会得到两个 BeerRepository bean - 模拟和真正的一个 - spring data rest 将通过 bean 名称 beerRepository 查找此存储库。

所以我尝试了这样的事情：

@Bean
public BeerRepository beerRepository() 
    return Mockito.mock(BeerRepository.class);

但我的 bean 总是被真正的存储库 bean 覆盖。

我正在使用内存数据库在我的测试中插入我的测试数据。这很好用，对您来说是一个简单的选择。

【讨论】：

那更像是一个集成测试，对吧？我已经这样做了（h2 数据库），但我还想对存储库进行单元测试（我不知道这是否有用）

一位 spring-data 维护者提供了一个非常有用的答案 - 他解释了为什么测试 repos 不太有用：***.com/a/23442457/5371736

在同一个问题中也有一个答案指向一个声称支持测试回购的实现 - 但我没有尝试过。 ***.com/a/28643025/5371736

@MatiasElorriaga 这个问题已经很老了，但总的来说，您不会以任何有意义的方式对存储库进行单元测试。除非您提供了具体的存储库实现，否则实际的存储库实现由 Spring Data REST 提供，因此您将测试他们的代码。

【参考方案2】：

由于@RepositoryRestResource 使REST 存储库成为一个spring bean，您可以使用Spring 注解：

@MockBean
RestRepository mockedRepository

然后使用mockito的

when(...mockedRepository.someMethod(any())).thenReturn(value)
