### Question:
PooledItemSourceFactory implements ItemSourceFactory { @Override public final boolean isBuffered() { return true; } protected  PooledItemSourceFactory(ItemSourcePool bufferedItemSourcePool); @Override final boolean isBuffered(); @Override ItemSource create(Object source, ObjectWriter objectWriter); @Override ItemSource createEmptySource(); @PluginBuilderFactory static PooledItemSourceFactory.Builder newBuilder(); @Override void start(); @Override void stop(); @Override boolean isStarted(); @Override boolean isStopped(); static final String PLUGIN_NAME; }### Answer:
@Test public void isBufferedReturnsTrue() { PooledItemSourceFactory pooledItemSourceFactory = new PooledItemSourceFactory(mock(ItemSourcePool.class)); boolean isBuffered = pooledItemSourceFactory.isBuffered(); assertEquals(true, isBuffered); }
