private function ImageCacheUrlTests::_ImagecacheCreateUrlTest in ImageCache 5.2

Same name and namespace in other branches

1. 6.2 tests/imagecache_create_url.test \ImageCacheUrlTests::_ImagecacheCreateUrlTest()

Function to actually perform URL tests.

Parameters

$clean_url: 'clean_url' setting for test.

$file_downloads: 'file_downloads' setting for test.

$file_directory_path: 'file_directory_path' setting for tests.

$preset: imagecache preset name to be used for test.

$path: file path to be used for generating output.

$expected: the url expected as output from imagecache_create_url

Note about the implementation: At first sight one might think this can be easily implemented with just setting the Drupal settings, calling imagecache_create_url() and checking the result. This does not work however because the url() function, which is used by imagecache_create_url(), caches the clean_url setting with an internal static variable. This means that only one setting of clean_url can be evaluated per page view. To make testing possible, this function creates a node with the PHP evaluator as input filter and puts a proper call to imagecache_create_url() in the node body. The node view, which is a page view on its own can then be checked for the correctly generated URL.

Class

Test class for testing imagecache_create_url() in several use cases with the different combinations of clean URLs and private/public download method.

Code

private function _ImagecacheCreateUrlTest($clean_url, $file_downloads, $file_directory_path, $preset, $path, $expected) {

  // Build node body (php code).
  $body = "<?php\n      // Change base_url\n      \$GLOBALS['base_url'] = 'http://example.com';\n      // Generate URL and check it.\n      echo imagecache_create_url('{$preset}', '{$path}');\n      ?>";

  // Create node.
  $node = $this

    'body' => $body,
    'format' => $this->input_format_id,
  ));

  // Show node.
  $this
    ->drupalGet(url('node/' . $node->nid, NULL, NULL, TRUE));

  // Check if expected url shows up
  $this
    ->assertWantedRaw($expected, t('[ImageCacheUrlTests] @clean_url + @file_downloads should return "@expected"', array(
