Tests for the Entity CRUD API.

Class

EntityLoadTestCase

Tests the entity_load() function.

Code

public function testEntityLoadConditions() {

  // Create a few nodes. One of them is given an edge-case title of "Array",
  // because loading entities by an array of conditions is subject to PHP
  // array-to-string conversion issues and we want to test those.
  $node_1 = $this
    ->drupalCreateNode(array(
    'title' => 'Array',
  ));
  $node_2 = $this

    'title' => 'Node 2',
  ));
  $node_3 = $this
    ->drupalCreateNode(array(
    'title' => 'Node 3',
  ));

  // Load all entities so that they are statically cached.
  $all_nodes = entity_load('node', FALSE);

  // Check that the first node can be loaded by title.
  $nodes_loaded = entity_load('node', FALSE, array(
    'title' => 'Array',
  ));
  $this
    ->assertEqual(array_keys($nodes_loaded), array(
    $node_1->nid,
  ));

  // Check that the second and third nodes can be loaded by title using an
  // array of conditions, and that the first node is not loaded from the
  // cache along with them.

    'title' => array(
      'Node 2',
      'Node 3',
