You can add a comment to your dataProvider array, to provide the same functionality, while not requiring multiple dataProviders.

public static function DataProvider()
{
    return array(
        'Invalid Id'      => array(123),
        'Failed Id'       => array(321),
        'Id Not Provided' => array(NULL),
);
}
