PHPunit to test catch block

I have a code like this one:

public function one()
{
   try {
      $this->two();
   } catch (Exception $E) {
      $this->three();
   }
}

How can i test that $this->three() function is called?

I've tried to "mock by code" $this->two() and throw error instead of it's original code, but that ends up with error caught by phpunit itself.

Tried setExpectedException, but it also doesn't solve the problem - catch runs inside phpunit again and just ignored.

Function $this->three() never called in both cases.

Thanks!
