Code

public function testFieldValuesAfterSerialize() {

  // 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.

    'language' => 'en',

  // Serialize the entity and the cloned object in order to destroy the field
  // 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 $values property.
  serialize($entity);
  serialize($clone);

  // Assert that the original and the cloned entity both have different names.
