How do mock for viewHelper in zf2 - php

Question

I'm trying to do mock for viewHelper and can't do this.
When I am trying to run phpunit I get the assert error "Failed asserting that two strings are equal." because the analiticHelper hasn't been overwriten. I wrote setAllowOverride(true) for my ServiseManager, but this didn't help.
Could you please tell me how can I do mock for viewHelper in Zend Framework 2?
I will appreciate your time and help!
Thanks!
