如何测试@Cacheable?

我正在努力在Spring Boot Integration Test中测试@Cacheable。这是我第二天学习如何进行集成测试以及我发现使用旧版本的所有示例。我还看到了一个assetEquals("some value", is())的示例,但没有使用import语句知道哪个依赖关系"是#34}。属于。测试在第二次失败

这是我的集成测试....

@RunWith(SpringRunner.class)
@DataJpaTest // used for other methods
@SpringBootTest(classes = TestApplication.class)
@SqlGroup({
        @Sql(executionPhase = ExecutionPhase.BEFORE_TEST_METHOD,
                scripts = "classpath:data/Setting.sql") })
public class SettingRepositoryIT {

    @Mock
    private SettingRepository settingRepository;

    @Autowired
    private Cache applicationCache;


    @Test
    public void testCachedMethodInvocation() {
        List<Setting> firstList = new ArrayList<>();
        Setting settingOne = new Setting();
        settingOne.setKey("first");
        settingOne.setValue("method invocation");
        firstList.add(settingOne);

        List<Setting> secondList = new ArrayList<>();
        Setting settingTwo = new Setting();
        settingTwo.setKey("second");
        settingTwo.setValue("method invocation");
        secondList.add(settingTwo);

        // Set up the mock to return *different* objects for the first and second call
        Mockito.when(settingRepository.findAllFeaturedFragrances()).thenReturn(firstList, secondList);

        // First invocation returns object returned by the method
        List<Setting> result = settingRepository.findAllFeaturedFragrances();
        assertEquals("first", result.get(0).getKey());

        // Second invocation should return cached value, *not* second (as set up above)
        List<Setting> resultTwo = settingRepository.findAllFeaturedFragrances();
        assertEquals("first", resultTwo.get(0).getKey()); // test fails here as the actual is "second."

        // Verify repository method was invoked once
        Mockito.verify(settingRepository, Mockito.times(1)).findAllFeaturedFragrances();
        assertNotNull(applicationCache.get("findAllFeaturedFragrances"));

        // Third invocation with different key is triggers the second invocation of the repo method
        List<Setting> resultThree = settingRepository.findAllFeaturedFragrances();
        assertEquals(resultThree.get(0).getKey(), "second");
    }
}

ApplicationContext,组件,实体,存储库和测试服务层。我这样做的原因是因为这个maven模块在其他模块中用作依赖。

@ComponentScan({ "com.persistence_common.config", "com.persistence_common.services" })
@EntityScan(basePackages = { "com.persistence_common.entities" })
@EnableJpaRepositories(basePackages = { "com.persistence_common.repositories" })
@SpringBootApplication
public class TestApplication {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

缓存配置....

@Configuration
@EnableCaching
public class CacheConfig {

    public static final String APPLICATION_CACHE = "applicationCache";

    @Bean
    public FilterRegistrationBean registerOpenSessionInViewFilterBean() {
        FilterRegistrationBean registrationBean = new FilterRegistrationBean();
        OpenEntityManagerInViewFilter filter = new OpenEntityManagerInViewFilter();
        registrationBean.setFilter(filter);
        registrationBean.setOrder(5);
        return registrationBean;
    }


    @Bean
    public Cache applicationCache() {
        return new GuavaCache(APPLICATION_CACHE, CacheBuilder.newBuilder()
                .expireAfterWrite(30, TimeUnit.DAYS)
                .build());
    }
}

正在测试的存储库....

public interface SettingRepository extends JpaRepository<Setting, Integer> {

    @Query(nativeQuery = true, value = "SELECT * FROM Setting WHERE name = 'featured_fragrance'")
    @Cacheable(value = CacheConfig.APPLICATION_CACHE, key = "#root.methodName")
    List<Setting> findAllFeaturedFragrances();
}

SettingRepositoryIT 的第一个问题是字段 settingRepository 上的 @Mock anotation。对于任何正常测试,集成测试或其他任何事情来说,这都是矛盾的。

你应该让Spring引入 class-under-test 的依赖项,在你的情况下是 SettingRepository

请查看此示例 @Autowired 如何用于测试中的,在此示例中 OrderService :< / p>

@RunWith(SpringRunner.class)
// ApplicationContext will be loaded from the
// static nested Config class
@ContextConfiguration
public class OrderServiceTest {

    @Configuration
    static class Config {

        // this bean will be injected into the OrderServiceTest class
        @Bean
        public OrderService orderService() {
            OrderService orderService = new OrderServiceImpl();
            // set properties, etc.
            return orderService;
        }
    }

    @Autowired
    private OrderService orderService;

    @Test
    public void testOrderService() {
        // test the orderService
    }

}

请参阅完整示例的文档:§ 15. Integration Testing

第二个问题是您不必测试@Cachable。您应该只测试您的实现。以下是Oliver Gierke关于如何测试它的一个很好的例子:How to test Spring's declarative caching support on Spring Data repositories?

在我的情况下,我想验证@Cacheable批注中的else表达式中的表达式,因此我认为这很有意义,并且我不测试Spring的代码。

我设法在不使用Spring Boot的情况下对其进行测试,因此它是普通的Spring测试:

@RunWith(SpringRunner.class)
@ContextConfiguration
public class MyTest {

    @Configuration
    @EnableCaching
    static class Config {

        @Bean
        public MyCacheableInterface myCacheableInterface() {
            return (authorization) -> createTestResult();
        }

        @Bean
        public CacheManager cacheManager() {
            return new ConcurrentMapCacheManager("myObject");
        }
    }

    @Autowired
    private MyCacheableInterface myCacheableInterface;

在MyCacheableInterface中,我具有以下注释:

public interface MyCacheableInterface {
    @Cacheable(value = "myObject", unless = "#result.?[Retorno.getSucesso() != 'S'].size() == #result.size()")
    List<MyObject> businessMethod(String authorization);
}
