PHPUnit: Test an abstract class without concrete methods

[csyukp5huy]

I've following abstract class and have a question about how to write a unit test for this. Is this in fact needed? As this class doesn't have any concrete methods.\[code\]<?phpabstract class PickupPoint_Abstract { public function __construct($client) {} public function getPickupPoints($countryCode, $postalCode, $city) {} public function getPickupPointDetails($pickupPointId, $countryCode) {} }\[/code\]
