junit@SpringBootTest for org.springframework.cache.cache

我已经在SpringBoot应用程序中安装了SpringEhcache。为缓存逐出实现了1个api。我正在为此写junits

以下是my Configuration.java中cacheManager的配置代码

 @Bean
    public CacheManager cacheManager()
    {
            EhCacheManagerFactoryBean factoryBean = new EhCacheManagerFactoryBean();
            factoryBean.setConfigLocation(new ClassPathResource("ehcache.xml"));
            factoryBean.setShared(true);
            return new EhCacheCacheManager(factoryBean.getObject());
    }

在我的测试类中，我无法模拟CacheManager，因为无法读取ehcache.xml

这是我的testClass：

import static org.junit.Assert.assertNotNull;
import static org.junit.Assert.assertTrue;
import static org.mockito.Mockito.when;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.Mockito;
import org.mockito.MockitoAnnotations;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.boot.test.context.TestConfiguration;
import org.springframework.cache.CacheManager;
import org.springframework.cache.ehcache.EhCacheCacheManager;
import org.springframework.cache.ehcache.EhCacheManagerFactoryBean;
import org.springframework.context.annotation.Bean;
import org.springframework.core.io.ClassPathResource;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.util.ReflectionTestUtils;



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

    @InjectMocks
    private DriverServiceImpl driverServiceImpl = null;

    @Mock
    private DriverMongoRepository mongoRepository;

    @Autowired
    private CacheManager ehCacheManager;

    @TestConfiguration
    public static class TestConfig
    {
        @Bean
        public CacheManager cacheManager()
        {
            EhCacheManagerFactoryBean factoryBean = new EhCacheManagerFactoryBean();
            factoryBean.setConfigLocation(new ClassPathResource("ehcache.xml"));
            factoryBean.setShared(true);
            return new EhCacheCacheManager(factoryBean.getObject());
        }
    }

    @Before
    public void setUp()
    {
        MockitoAnnotations.initMocks(this);

    }

    @Test
    public void testEvictCache() throws Exception
    {
      //Trying to mock ehCacheManager similar to cacheManager() of configuration.java

        String response = driverServiceImpl.evictCache("dummyUser", "getDriver", "1");
    }
}

因为我的ehCacheManager没有被正确地模拟，所以我在 Cache Cache=ehCacheManager.getCache（“getDriver”）

有人能帮我模拟一下类似configuration.java的CacheManager（）的CacheManager吗

希望我的问题清楚！！

提前感谢

，下面是我如何实现spring框架提供的ehcache缓存的示例代码

 @SpringBootTest
public class DriverServiceTest
{

    @InjectMocks
    private DriverServiceImpl driverServiceImpl  = null;

    @Mock
    private CacheManager mockCacheManager;

    private static CacheManager cacheManager;

    @BeforeClass
    public static void initialClassSetUp()
    {
        @SuppressWarnings("resource")
        ApplicationContext context = new AnnotationConfigApplicationContext(SpringConfig.class);
        cacheManager = context.getBean("cacheManager", org.springframework.cache.ehcache.EhCacheCacheManager.class);
    }

    @Before
    public void setUp()
    {
        MockitoAnnotations.initMocks(this);
    }

    @Configuration
    @EnableCaching
    static class SpringConfig
    {
        @Bean
        public CacheManager cacheManager()
        {
            EhCacheManagerFactoryBean factoryBean = new EhCacheManagerFactoryBean();
            factoryBean.setConfigLocation(new ClassPathResource("ehcache.xml"));
            factoryBean.setShared(true);
            EhCacheCacheManager ehCacheCacheManager = new EhCacheCacheManager();
            ehCacheCacheManager.setCacheManager(factoryBean.getObject());
            return ehCacheCacheManager;
        }
    }

   @Test
    public void testEvictCacheKeyNotExist() throws Exception
    {
        Cache cache = cacheManager.getCache("getSubaccounts");
        ReflectionTestUtils.setField(driverServiceImpl , "ehCacheManager", cacheManager);
        when(mockCacheManager.getCache(Mockito.anyString()))
                .thenReturn(cache);
        String actualValue = driverServiceImpl.evictCache("dummyUserName", "getSubaccounts",
                "dummyKeyName");
        assertTrue(actualValue.equals("key not exists"));
    }

以下是需要注意的要点：

需要在config静态类上添加@EnableCaching注释和@Configuration

cacheManager值需要分配给initialClassSetUp（）中的本地cacheManager，因为它应该在每个类中执行一次

现在，相同的cacheManager可以通过
ReflectionTestUtils.setField（driverServiceImpl，“ehCacheManager”，cacheManager）

还有塔达！！现在你可以坚持你的观点了

您可以发布测试用例的完整代码吗？为什么您不能读取ehcache.xml？您可以删除所有注释代码并写出您的测试用例和您想要断言的内容吗。你的测试代码毫无意义
