Testing both return value and E_NOTICE/E_USER_NOTICE

gistfile1.php

<?php
class ClassWithError {
    public function multiplyByTen($value = 0) {
        if (!$value) {
            trigger_error('Value is missing', E_USER_NOTICE());
            return false;
        }
        
        return $value * 10;
    }
}
?>

I want to test both that it triggers an error and that it returns false. 
Currently I'm doing this with two tests, one that expects the PHPUnit_Framework_Error_Notice 
and one where I turn it of with PHPUnit_Framework_Error_Notice::$enabled = false while
asserting that the return value is false.

It works, but this will display the error message when running phpunit and it's not that pretty. Any better solutions?
