php - PHPUnit-Netbeans class not found exception -

i integrated phpunit netbeans , want generate tests code.

<?php  /**      * action user      *      * user api      *      * @link http://getfrapi.com      * @author frapi <frapi@getfrapi.com>      * @link rsmobile/user/:id      */     class action_user extends frapi_action implements frapi_action_interface     {      } ?> 

i tried right clicking , selecting tools->create phpunit tests. gave error :

fatal error: class 'frapi_action' not found in /users/username/documents/.../src/    frapi/custom/action/user.php on line 12 

then added dummy frapi_action class in file user.php , generated skeleton class.

<?php  /**      * action user      *      * user api      *      * @link http://getfrapi.com      * @author frapi <frapi@getfrapi.com>      * @link rsmobile/user/:id      */      class  frapi_action {}       class action_user extends frapi_action implements frapi_action_interface     {      } ?> 

why gave class not found error? how solve it?

i solved adding path of file containing frapi_action class.

require_once 'path/of/file';
