  // Create a test entity with a translation, which will internally trigger
  // entity cloning for the new translation and create references for some of
  // the entity properties.

  // Alter the name field value of the cloned entity object.
  $clone->setName('clone');

  // objects and put the field values into the entity property $values, so
  // that on accessing a field again it will be newly created with the value
  // from the $values property.
