Code

public function testFieldSerialization() {
  $field = $this
    ->createTestField('test', 'entity:entity:entity_test_mulrev_changed');
  $serialized = unserialize(serialize($field));

  // Call getIndex() and serialize() on the restored field to make "equals"
  // work correctly. (__sleep() sets some properties as a by-product which the
  // serialized version doesn't have – $indexId, in this case.)
  $serialized
    ->getIndex();
  serialize($serialized);
  $this
    ->assertEquals($field, $serialized);
