### Question:
GlusterPath implements Path { @Override public Path normalize() { List<String> newParts = new LinkedList<String>(); for (String part : parts) { if (part.equals("..")) { newParts.remove(newParts.size() - 1); } else if (!part.equals(".") && !part.isEmpty()) { newParts.add(part); } } return new GlusterPath(fileSystem, newParts.toArray(new String[]{}), absolute); } 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 testNormalize() { Path p = new GlusterPath(mockFileSystem, "foo assertEquals(new GlusterPath(mockFileSystem, "foo/bar"), p.normalize()); p = new GlusterPath(mockFileSystem, "foo/./bar"); assertEquals(new GlusterPath(mockFileSystem, "foo/bar"), p.normalize()); p = new GlusterPath(mockFileSystem, "foo/././bar"); assertEquals(new GlusterPath(mockFileSystem, "foo/bar"), p.normalize()); p = new GlusterPath(mockFileSystem, "foo/baz/../bar"); assertEquals(new GlusterPath(mockFileSystem, "foo/bar"), p.normalize()); p = new GlusterPath(mockFileSystem, "foo/baz/../baz/../bar"); assertEquals(new GlusterPath(mockFileSystem, "foo/bar"), p.normalize()); }
