Kohana 3.14 fails at unit testing with message class 'Kohana' not found-Collection of common programming errors

I have a kohana website that works okay, and I started unit testing (retrospectively, I know it is not the best practice)

The first error I get and I cannot get rid of is quite puzzling:

Fatal error: Uncaught exception ‘LogicException’ with message ‘Passed array does not specify an existing static method (class ‘Kohana’ not found)’ in /Users/dananicula/Sites/mnib1/application/bootstrap.php:44

in bootstrap, line 44 is:

 spl_autoload_register(array('Kohana', 'auto_load'));

and class Kohana actualy exists in system/classes/kohana.php

Any hints? Opinions? Suggestions? Thank you!
