### Question:
GlusterPath implements Path { @Override public Iterator<Path> iterator() { List<Path> list = new ArrayList<Path>(parts.length); if (parts.length >= 1 && !parts[0].isEmpty()) { for (String p : parts) { list.add(new GlusterPath(fileSystem, p)); } } return Collections.unmodifiableList(list).iterator(); } GlusterPath(GlusterFileSystem fileSystem, String path);   GlusterPath(GlusterFileSystem fileSystem, String[] parts, boolean absolute); @Override boolean isAbsolute(); @Override Path getRoot(); @Override Path getFileName(); @Override Path getParent(); @Override int getNameCount(); @Override Path getName(int i); @Override Path subpath(int i, int i2); @Override boolean startsWith(Path path); @Override boolean startsWith(String s); @Override boolean endsWith(Path path); @Override boolean endsWith(String s); @Override Path normalize(); @Override Path resolve(Path path); @Override Path resolve(String s); @Override Path resolveSibling(Path path); @Override Path resolveSibling(String s); @Override Path relativize(Path path); @Override URI toUri(); @Override Path toAbsolutePath(); @Override Path toRealPath(LinkOption... linkOptions); @Override File toFile(); @Override WatchKey register(WatchService watchService, WatchEvent.Kind<?>[] kinds, WatchEvent.Modifier... modifiers); @Override WatchKey register(WatchService watchService, WatchEvent.Kind<?>... kinds); @Override Iterator<Path> iterator(); @Override int compareTo(Path path); String toString(); String getString();  }### Answer:
@Test public void testIterator() { Path p = new GlusterPath(mockFileSystem, "/foo/bar"); Iterator<Path> it = p.iterator(); assertEquals(new GlusterPath(mockFileSystem, "foo"), it.next()); assertEquals(new GlusterPath(mockFileSystem, "bar"), it.next()); p = new GlusterPath(mockFileSystem, "/"); it = p.iterator(); assertFalse(it.hasNext()); }
