Given a brief description of a Microwave Oven System. Please complete the requested modeling and testing tasks.

Software scope: A Microwave Oven System (MOS) controls the operations of a microwave oven through a panel of buttons. The user can select the power level (either half-power or full-power), then input the cooking time, and finally press Start to start the cooking operation. The food is cooked for the given time unless Pause is pressed. The user can press Pause again to resume cooking, or press Cancel to cancel the cooking. For safety reasons, the oven should not operate when the door is open and, on completion of cooking, a buzzer is sounded. To meet the personal requirement of users, MOS will log the users’ most frequently used cooking time and set it as the default.
