(b) Following is a simple use case for an Automatic Teller Machine (ATM) funds transfer transaction and its corresponding diagram. Derive test cases from the given use case and diagram. Only provide one line summary; input test data; and expected result for each test case (you can use your own assumptions wherever required however you need to clearly list those assumptions). Use case: A transfer transaction asks the customer to select a type of account to transfer from (e.g. checking) from a menu of possible accounts, to choose a different account to transfer to, and to type in a dollar amount to transfer. No further action is required once the transaction is approved by the bank before printing the receipt. A transfer transaction can be cancelled by the customer pressing the Cancel key any time prior to entering a dollar amount and confirming transaction. [12 marks]
