Get size of entries in ehcache 3

I want to use ehcache3. For some junit tests, I need to know the size of entries in the cache. I dont find a method. How can get the size of entries (not memory) in ehcache 3?

For Ehcache 3.x you have the answer here from loicmathieu:

StatisticsService statisticsService = new DefaultStatisticsService();
CacheManager cacheManager = CacheManagerBuilder.newCacheManagerBuilder()
    .using(statisticsService)
    .build();
cacheManager.init();

CacheStatistics ehCacheStat = statisticsService.getCacheStatistics("myCache");
ehCacheStat.getTierStatistics().get("OnHeap").getMappings();//nb element in heap tier
ehCacheStat.getTierStatistics().get("OnHeap").getOccupiedByteSize()//size of the tier

You can check the official Ehcache test code here

Since it's only for test, your best bet is

    int count = 0;
    for(Cache.Entry<Long, String> entry : cache) {
        count++;
    }
