I've been digging around in zf2 and apparently they believe in only two exit statuses: `0` and `1` (see [Zend\Test\PHPUnit\Controller\AbstractControllerTestCase:428](https://github.com/zendframework/zf2/blob/master/library/Zend/Test/PHPUnit/Controller/AbstractControllerTestCase.php#L428))

This would explain why they always return `1` in the console exception strategy.
