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->drupalCreateNode(array(
        '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.
    $nodes_loaded = entity_load('node', FALSE, array(
        'title' => array(
            'Node 2',
            'Node 3',
        ),
    ));
    ksort($nodes_loaded);
    $this->assertEqual(array_keys($nodes_loaded), array(
        $node_2->nid,
        $node_3->nid,
    ));
