### Question:
AbstractCache implements IDataCache<T> { @Override public long getMaxCacheSize() { return maxCacheSize; } AbstractCache(S entries, IDataStorage<T> cachedStorage, long maxCacheSize,
      Predicate<T> cachingRule); @Override long getMaxCacheSize(); @Override boolean setMaxCacheSize(long maxCacheSize); @Override long getCurrentCacheSize(); @Override long getFreeSpace(); @Override boolean hasStorageFor(long size); @Override void cacheData(T data); @Override void uncacheData(T data); @Override boolean dataIsCachable(T data); @Override boolean dataIsInCache(long id); @Override void clearCache(); @Override boolean dataExists(long id); @Override T loadData(long id); @Override boolean saveData(T data); @Override boolean dataIsStorable(T data); @Override boolean deleteData(T data);  }### Answer:
@Test public void testGetMaxCacheSize() { AbstractCacheWrapper uut = new AbstractCacheWrapper(entries, storageAll, IDataCache.STD_MAX_CACHE_SIZE, predicate -> true); assertEquals(IDataCache.STD_MAX_CACHE_SIZE, uut.getMaxCacheSize()); uut = new AbstractCacheWrapper(entries, storageAll, 1234567890, predicate -> true); assertEquals(1234567890, uut.getMaxCacheSize()); }
