Usage

From source file:com.thoughtworks.acceptance.WriteReplaceTest.java

public void testReplacesAndResolves() throws IOException, ClassNotFoundException {
    Thing thing = new Thing(3, 6);

    // ensure that Java serialization does not cause endless loop for a Thing
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    ObjectOutputStream oos = new ObjectOutputStream(baos);
    oos.writeObject(thing);/*  w ww  .ja  va2s .  com*/
    oos.close();

    ByteArrayInputStream bais = new ByteArrayInputStream(baos.toByteArray());
    ObjectInputStream ios = new ObjectInputStream(bais);
    assertEquals(thing, ios.readObject());
    ios.close();

    // ensure that XStream does not cause endless loop for a Thing
    xstream.alias("thing", Thing.class);

    String expectedXml = "" + "<thing>\n" + "  <a>3000</a>\n" + "  <b>6000</b>\n" + "</thing>";
