Consider the simplified logic below for crediting money to a bank account.

Receive money and account number to be credited

IF account number is valid

IF customer account is active

Store current account balance as oldBalance

Credit money to account

IF oldBalance < zero

IF balance now >= zero

Set message "Overdraft cleared"

ELSE

Set message "A/c overdrawn"

ENDIF

ELSE

Set message = "You have more money"

ENDIF

IF account holder is VIP customer

Send message by email to customer

ENDIF

ELSE

Set message "A/c inactive"

Send message by email to supervisor

ENDIF

ELSE

Add 1 to count of invalid inputs

ENDIF

What percentage of decision testing coverage has been achieved by the following suite of test cases?

Test Case A - Account number valid, account is active, oldBalance = -100, balance now = +200, not a VIP

customer

Test Case B - Account number valid, account is active, oldBalance = -100, balance now = -50, is a VIP

You are working on a new product that will provide an online pizza ordering service. Not everyone wants to create a frequent-eater pizza account, so the user can either log in to their existing account, create an account or proceed as a “guest" user. People with existing accounts have the option to update their accounts including changing address, changing credit card information and changing phone number. New account creation requires the user to enter their address, credit card information and phone number. This information Is validated to be sure the address matches the credit card information. Once the user logs in, they are able to order their pizza. They can request up to five different pizzas and can select different ingredients on each. A user is allowed to pick up to 10 different ingredients per pizza. They can also select from a pre-defined set of ingredients as follows: “meat lovers", “all veggie’, “cheese please’, and “throw it all on". The busiest day of the year for this product will be the day of the final football game of the professional season. In addition to the normal high load, the company will also be running a special on the “cheese please" pizza (buy 3 get 2 more free). The new product will need to handle a load that Is expected to be twice as high as the load on the old product last year. Given this information, what is an important item that should be addressed In the architectural specification?
