### Question:
MboxIterator implements Iterable<CharBufferWrapper>, Closeable { public Iterator<CharBufferWrapper> iterator() { return new MessageIterator(); } private  MboxIterator(final File mbox,
                         final Charset charset,
                         final String regexpPattern,
                         final int regexpFlags,
                         final int MAX_MESSAGE_SIZE); Iterator<CharBufferWrapper> iterator(); void close(); static Builder fromFile(File filePath); static Builder fromFile(String file); static String bufferDetailsToString(final Buffer buffer);  }### Answer:
@Test public void testIterator() throws FileNotFoundException, IOException { iterateWithMaxMessage(DEFAULT_MESSAGE_SIZE); }
@Test public void testIterator() throws FileNotFoundException, IOException { System.out.println("Executing " + name.getMethodName()); iterateWithMaxMessage(DEFAULT_MESSAGE_SIZE); }
