3. 10 core/tests/Drupal/Tests/EntityViewTrait.php \Drupal\Tests\EntityViewTrait::buildEntityView()

Builds the renderable view of an entity.

Entities postpone the composition of their renderable arrays to #pre_render functions in order to maximize cache efficacy. This means that the full renderable array for an entity is constructed in \Drupal::service('renderer')->render(). Some tests require the complete renderable array for an entity outside of the render process in order to verify the presence of specific values. This method isolates the steps in the render process that produce an entity's renderable array.

Parameters

\Drupal\Core\Entity\EntityInterface $entity: The entity to prepare a renderable array for.

string $view_mode: (optional) The view mode that should be used to build the entity.

null $langcode: (optional) For which language the entity should be prepared, defaults to the current content language.

Return value

array
