Im helper方法使用ehcache,以减少对Db的查询。现在想要实现JUnit + Mockito测试以确保ehcache正常工作。有这样的测试变体:
@Autowired
private DBService service;
@Autowired
private DiscountHelper discountHelper;
@Autowired
private CacheManager cacheManager;
@Before
public void setUp() throws Exception {
assertNotNull(cacheManager);
}
@Test
public void testGetDiscountWithCache() throws RuntimeException,
InterruptedException {
String id1 = "id1";
String id2 = "id2";
String id3 = "id3";
List<String> discountsId = new ArrayList<String>();
discountsId.add(id1);
discountsId.add(id2);
discountsId.add(id3);
List<Map<String, Object>> attrList = new ArrayList<Map<String, Object>>();
attrList.add(new Discount().getAttributes());
attrList.add(new Discount().getAttributes());
attrList.add(new Discount().getAttributes());
Cache cache = cacheManager.getCache(DiscountHelper.CACHE_NAME);
assertNotNull(cache);
assertEquals(0, cache.getSize());
// First run with empty cache
when(service.getAllItems(eq(Discount.TABLE_NAME))).thenReturn(attrList);
List<Discount> actualResult = discountHelper
.getAllDiscountsUsingCache();
assertNotNull(actualResult);
assertEquals(attrList.size(), actualResult.size());
verify(service).getAllItems(eq(Discount.TABLE_NAME));
cache = cacheManager.getCache(DiscountHelper.CACHE_NAME);
// In cache should be 1 record
assertNotNull(cache);
assertEquals(1, cache.getSize());
}
测试方法是:
@Cacheable(cacheName = CACHE_NAME, refreshInterval = 1000 * 900, decoratedCacheType = DecoratedCacheType.REFRESHING_SELF_POPULATING_CACHE)
public List<Discount> getAllDiscountsUsingCache() throws RuntimeException,
InterruptedException {
List<Map<String, Object>> result = dbService
.getAllItems(Discount.TABLE_NAME);
List<Discount> discountList = new ArrayList<Discount>();
for (Map<String, Object> entry : result) {
discountList.add(new Discount(entry));
}
return discountList;
}
这完美有效。在测试中,我确信在调用方法之后,我在缓存中得到了一些东西。如您所见,我还验证了在db服务中调用了getAllItems方法。这对于第一次调用很有用。接下来,我在同一个测试中添加第二次调用discountHelper.getAllDiscountsUsingCache():
when(service.getAllItems(eq(Discount.TABLE_NAME))).thenReturn(attrList);
actualResult = discountHelper
.getAllDiscountsUsingCache();
assertNotNull(actualResult);
assertEquals(attrList.size(), actualResult.size());
verify(service, times(0)).getAllItems(eq(Discount.TABLE_NAME));
所以我只想检查第二次调用时,通过此验证方法getAllItems不会调用DB服务:verify(service,times(0))。getAllItems(eq(Discount.TABLE_NAME));结果将从缓存中获得。
但是它不起作用,我仍然可以调用DB方法。我找到了这个教程http://blog.goyello.com/2010/07/29/quick-start-with-ehcache-annotations-for-spring/并尝试使用委托对象进行ehcache测试,但它仍然会在测试时调用db方法。怎么了? 顺便说一下,在生产中,ehcache在tomcat的日志中看起来很好,所以这是一个测试问题。任何建议如何解决?
答案 0 :(得分:2)
在第二次调用中,您在Spring上下文初始化期间使用Springockito创建的相同模拟对象(服务)(我假设从问题的标签中)。模拟会记住第一次调用时的getAllItems()调用。你可以:
reset(service)
,或
