### Question:
BaseByteArrayReader implements ByteArrayReader { @Override public void release() { IoUtil.release(dataReader, lenReader, posReader); } BaseByteArrayReader(ByteReader dataReader, LongReader posReader, IntReader lenReader); @Override boolean isReadable(); @Override byte[] get(long pos); @Override InputStream getStream(long pos); @Override void release();  }### Answer:
@Test public void release() { mockStatic(IoUtil.class); new BaseByteArrayReader(dataReader, posReader, lenReader).release(); verifyStatic(IoUtil.class); IoUtil.release(dataReader, lenReader, posReader); }
