Я имею утруждая насмешливый класс net.sf.ehcache.Cache с помощью PowerMock Вот класс, я хочу, чтобы проверитьPowerMock и класс net.sf.ehcache.Cache
package com.services.amazon;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import net.sf.ehcache.Cache;
import net.sf.ehcache.CacheManager;
import net.sf.ehcache.Element;
public class CacheServices {
/** Local log variable. **/
private static final Logger LOG = LoggerFactory.getLogger(CacheServices.class);
private CacheManager cacheManager;
public void setCacheManager(CacheManager argCacheManager) {
cacheManager = argCacheManager;
}
public boolean replaceItemInCache(String cacheName, Object cacheKey, Object cacheObject) {
boolean result = false;
Cache cache = cacheManager.getCache(cacheName);
if (cache == null) {
return result;
}
int initialCacheSize1 = cache.getSize();
Element retrievedCacheObject = cache.get(cacheKey);
if (retrievedCacheObject != null) {
LOG.info("Object exists for the cacheKey of {} - now removing from cache", cacheKey);
boolean removeFromCacheResult = cache.remove(cacheKey);
}
int initialCacheSize2 = cache.getSize();
Element newCacheElement = new Element(cacheKey, cacheObject);
cache.put(newCacheElement);
int finalCacheSize = cache.getSize();
Object[] logParams = new Object[]{initialCacheSize1, initialCacheSize2, finalCacheSize};
LOG.info("initialCacheSize1:{}, initialCacheSize2:{}, finalCacheSize:{}", logParams);
result = true;
return result;
}
}
И мой тестовый класс
package com.services.amazon;
import static org.junit.Assert.assertTrue;
import org.easymock.EasyMock;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.powermock.api.easymock.PowerMock;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;
import net.sf.ehcache.Cache;
import net.sf.ehcache.CacheManager;
import net.sf.ehcache.Element;
@RunWith(PowerMockRunner.class)
@PrepareForTest({CacheServices.class, CacheManager.class, Cache.class, Element.class})
public class TestCacheServices {
CacheServices cacheServices;
CacheManager mockCacheManager;
Cache mockCache;
@Before
public void setUp() {
cacheServices = new CacheServices();
mockCacheManager = PowerMock.createMock(CacheManager.class);
mockCache = PowerMock.createMock(Cache.class);
cacheServices.setCacheManager(mockCacheManager);
}
@Test
public void testReplaceItemInCache_SuccessObjectExistsInCache() {
String cacheName = "cache";
String cacheKey = "cache";
Object cacheObject = new Object();
Element dummyElement = new Element("Key", "value");
EasyMock.expect(mockCacheManager.getCache(EasyMock.anyString())).andReturn(mockCache);
EasyMock.expect(mockCache.get(EasyMock.anyObject())).andReturn(dummyElement);
EasyMock.expect(mockCache.getSize()).andReturn(1).atLeastOnce();
EasyMock.expect(mockCache.remove(EasyMock.anyObject())).andReturn(true);
mockCache.put(EasyMock.isA(Element.class));
EasyMock.expectLastCall();
EasyMock.replay(mockCacheManager);
PowerMock.replay(mockCache);
boolean result = cacheServices.replaceItemInCache(cacheName, cacheKey, cacheObject);
assertTrue("Expected True but was " + result, result);
EasyMock.verify(mockCacheManager);
PowerMock.verify(mockCache);
}
}
консоль ошибок я получаю от выполнения теста заключается в следующем
java.lang.AssertionError:
Unexpected method call Cache.get("cache"):
Cache.get(<any>): expected: 1, actual: 0
Cache.remove(<any>): expected: 1, actual: 0
Cache.put(isA(net.sf.ehcache.Element)): expected: 1, actual: 0

Can кто-нибудь указывает мне, что я могу делать неправильно? Я понимаю, класс Cache является окончательным, и я прочитал соответствующую документацию
Благодаря Damien
в 'CacheServices', является' кэша Manager.getCache (cacheName); 'return' null'? – thokuest
его нет - он возвращает фиктивный экземпляр кэша, как ожидалось –
