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',

    // array of conditions, and that the first node is not loaded from the
    // cache along with them.
