How to use XStream to generate xml from objects

I have to instrumentalize my code to generate tests. For that purpose, I use serialization to capture my objects state from the server while running some system tests. And I use the generated files for my IT-Tests using deserialization.

My colleague Fabrizio provided me with a neat utility that generates json files from all my serializable classes.

But I was confronted with difficulties with the complexity of some object graphs, so I use Xstream to generat xml.

Here's how to dump an object to xml:

  XStream xstream = new XStream();
  String xml = xstream.toXML(myObject);
  String filePath = "output.xml";
  try{
      new File(filePath).createNewFile();
      try (Writer writer = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(filePath), "utf-8"))) {
          writer.write(xml);
          writer.flush();
      }
  } catch (IOException e){
      e.printStackTrace();
  }
