protected function ImageDimensionsTest::getImageTag in Drupal 8

Same name and namespace in other branches

1. 9 core/modules/image/tests/src/Functional/ImageDimensionsTest.php \Drupal\Tests\image\Functional\ImageDimensionsTest::getImageTag()

Render an image style element.

Function drupal_render() alters the passed $variables array by adding a new key '#printed' => TRUE. This prevents next call to re-render the element. We wrap drupal_render() in a helper protected method and pass each time a fresh array so that $variables won't get altered and the element is re-rendered each time.
