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 testScaleEffect() {
  // @todo: need to test upscaling.
  $this->assertTrue(image_scale_effect($this->image, array('width' => 10, 'height' => 10)), 'Function returned the expected value.');
  $this->assertToolkitOperationsCalled(array('resize'));

  // Check the parameters.
  $calls = image_test_get_all_calls();
  $this->assertEqual($calls['resize'][0][1], 10, 'Width was passed correctly');
  $this->assertEqual($calls['resize'][0][2], 5, 'Height was based off aspect ratio and passed correctly');
}
