Inter-class test technique between black-box-class and white-box-class for component customization failures

For software component customization failures, we propose an inter-class test technique between the black-box class, which represents the `implementation´, and the white-box class, which is the `interface´ for the component. Our proposed test technique is based on a fault injection technique where a fault is injected into the component interface. For our technique, we first extract the component customization patterns and fault injection targets. We then define the fault injection operators which are applied to the fault injection targets. Since the fault injection operators can cover all possible failures that can occur within component customization, the proposed testing technique is suitable for component customization testing
