Tests for image.module.

Class

ImageEffectsUnitTest

Use the image_test.module's mock toolkit to ensure that the effects are properly passing parameters to the image toolkit.

Code

function testImageEffectsCaching() {
  $image_effect_definitions_called =& drupal_static('image_module_test_image_effect_info_alter');

  // First call should grab a fresh copy of the data.
  $effects = image_effect_definitions();
  $this
    ->assertTrue($image_effect_definitions_called === 1, 'image_effect_definitions() generated data.');

  // Second call should come from cache.
  drupal_static_reset('image_effect_definitions');
  drupal_static_reset('image_module_test_image_effect_info_alter');
  $cached_effects = image_effect_definitions();
  $this
    ->assertTrue(is_null($image_effect_definitions_called), 'image_effect_definitions() returned data from cache.');
  $this
    ->assertTrue($effects == $cached_effects, 'Cached effects are the same as generated effects.');
