Ame 15 marks] Question 3. (15 marks] A. Software test design is an important task for software test engineers. A good test engineer always knows how to come out quality test cases, performing effective tests to uncover as many bugs as possible. Discuss the two different testing techniques. Test cases should be developed for each use-case scenario. Consider the following use case diagram for an ATM machine model, generate 4 test cases for different scenarios.

The detailed modeling is translated into programming code. Draw a detailed class diagram for ATM machine model. You can use the above use case design as a partial reference if necessary to aid you in your personal design [4 marks) C. An ATM is initially turned off. After the power is turned on, ATM performs startup action and enters Self-Test state. If the test fails, ATM goes into Out of Service state, otherwise there is tigerless transition to the Idle state. In this state ATM waits for customer interaction. The ATM state changes from Idle to Serving Customer when the customer inserts banking or credit card in the ATM's card reader. On entering the Serving Customer state, the entry action readCard is performed. Note that transition from Serving Customer state back to the Idle state could be triggered by cancel event as the customer could cancel transaction at any time. Draw UML state diagram. [3 marks] 110
