  $field = FieldConfig::create($this->fieldDefinition);
  $field
    ->save();
  $field_name = $this->fieldStorage
    ->getName();

  // Test that constraints are applied to configurable fields. A TestField and
  // a Range constraint are added dynamically to limit the field to values
  // between 0 and 32.
  // @see field_test_entity_bundle_field_info_alter()
  \Drupal::state()
    ->set('field_test_constraint', $field_name);

  // Clear the field definitions cache so the new constraints added by
  // field_test_entity_bundle_field_info_alter() are taken into consideration.
  \Drupal::service('entity_field.manager')
    ->clearCachedFieldDefinitions();

  // Test the newly added property constraints in the same request as when the
  // caches were cleared. This will test the field definitions that are stored
  // in the static cache of
  // \Drupal\Core\Entity\EntityFieldManager::getFieldDefinitions().
  $this
    ->doFieldPropertyConstraintsTests();

  // In order to test a real-world scenario where the property constraints are
  // only stored in the persistent cache of
  // \Drupal\Core\Entity\EntityFieldManager::getFieldDefinitions(), we need to
  // simulate a new request by removing the 'entity_field.manager' service,
  // thus forcing it to be re-initialized without static caches.
  \Drupal::getContainer()
    ->set('entity_field.manager', NULL);

  // This will test the field definitions that are stored in the persistent
  // cache by \Drupal\Core\Entity\EntityFieldManager::getFieldDefinitions().
