[fw-general] Unit testing ZF objects

[Mike A]

I can unit test individual ZF objects with PHPUnit if I take the object 
into my own project folder and strip out PHPUnit references. If, 
however, I set the directory path to the ZF object in the library folder 
on my server I get errors like "Call to undefined method 
PHPUnit_Util_Filter::addFileToFilter() in 
E:\xampp1.7.3\xampp\libraries\ZF-1.11.0\tests\Zend\Controller\_files\EmptyController.php 
on line 25".

Please, could someone advise on the correct way to run tests supplied 
within the ZF library.
