Video Tutorial on Unit Testing with the Zend Framework with Zend_Test and PHPUnit

A useful video tutorial on how to setup unit testing with the Zend Framework using Eclipse PDT or Zend Studio:

Error ‘php.exe’ is not recognized as an internal or external command when calling phpunit on Windows XP/Vista/7

This may be caused by the PHP_PEAR_PHP_BIN environment variable not being set correctly.

To fix this go to Advanced System Settings in Control Panel/System & Maintenance/System.

Select Environment Variables.

Find variable PHP_PEAR_PHP_BIN and change the value from ./php.exe to the correct path\to\php.exe on your system.

$nextSibling = $element->xpath("following-sibling::ElementName");

To reference the first sibling following the element:

$firstSiblingElement = $nextSibling[0];
