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 testDesaturateEffect() {
  $this
    ->assertTrue(image_desaturate_effect($this->image, array()), 'Function returned the expected value.');
  $this
    ->assertToolkitOperationsCalled(array(
    'desaturate',
  ));

  // Check the parameters.
  $calls = image_test_get_all_calls();
  $this
    ->assertEqual(count($calls['desaturate'][0]), 1, 'Only the image was passed.');
}
