Question 1

Below is pseudo-code which calculates a customer's cruise credits based on past cruise history: PROGRAM CALC CRUISE CREDITS (CUST_ID) COUNT_CRUISES, CRUISE_CREDITS, LOYALTY_RATING: INTEGER CRUISE_LENGTH, CRUISE_ACCOM_TYPE: VAR LOYALTY_RATING = 0 COUNT_CRUISES = 0 CRUISE_LENGTH = 0 CRUISE_ACCOM_TYPE = 0 BEGIN READ CUSTOMER'S CRUISE HISTORY TO OBTAIN COUNT OF CRUISES READ CRUISE_HISTORY (CUST_ID) WHILE COUNT_CRUISES != -1 DO READ CUSTOMER'S NEXT CRUISE READ NEXT_CRUISE IF CRUISE_ACCOM_TYPE = 3 THEN CRUISE_CREDITS = CRUISE_CREDITS + 5 ELSE IF CRUISE_ACCOM_TYPE = 2 THEN CRUISE_CREDITS = CRUISE_CREDITS + 3 ELSE CRUISE_CREDITS = CRUISE_CREDITS + 2 ENDIF ENDIF COUNT_CRUISES = COUNT_CRUISES - 1 ENDWHILE LOYALTY_RATING = CRUISE_CREDITS / COUNT_CRUISES WRITE ("CRUISE CREDIT TOTAL IS:") WRITE (CRUISE_CREDITS) END PROGRAM CALC CRUISE CREDITS The code contains data flow anomalies on lines 14 and 27. Which examples of data flow anomalies can be found on these lines?

Options :

A : Line 14: Cruise_Credits is not assigned a value (defined) before being used Line 27: Loyalty_Rating is defined but not subsequently used

B : Line 14: Cruise_Credits is defined but not subsequently used Line 27: Loyalty_Rating is not assigned a value (defined) before being used

C : Line 14: Cruise_Credits is re-defined before being used Line 27: Loyalty_Rating is defined but not subsequently used

D : Line 14: Cruise_Credits should not be declared as an integer Line 27: Loyalty_Rating should be calculated within the While loop

Answer: C

Question 2

If you are flying with an economy ticket, there is a possibility that you may get upgraded to business class,especially if you hold a gold card in the airline’s frequent flier program. If you don’t hold a gold card, there isa possibility that you will get ‘bumped’ off the flight if it is full and you check in late. This is shown in thefigure hereafter. Note that each box (i.e. statement) has been numbered.Three tests have been run:Test 1: Gold card holder who gets upgraded to business classTest 2: Non-gold card holder who stays in economyTest 3: A person who is bumped from the flightWhat is the statement coverage of these three tests?

Options :

A : 60%

B : 70%

C : 80%

D : 90%

Answer: C

Question 3

The developers have suggested test set A is adequate to test the program opposite:

When executing test set A through the program which statements are exercised?

Options :

A : All

B : All, but statement 22

C : All, but statement 27, 28 and 29

D : All, but statement 22, 27, 28 and 29

Answer: D

Question 4

A developer has spent three days looking at a system that crashes now and then. The problem was causedby two coding faults:i. A variable was being used but had not been defined;ii.There was a ‘goto’ statement to an undefined label

Options :

A : Static analysis tool

B : Code coverage tool

C : Dynamic analysis tool

D : Test execution tool

Answer: A

Question 5

Options :

A : Finite state machines are used to describe the intended execution-time behavior of a software-controlled system.

B : Random sets of threads of execution are generated as test cases.

C : Large sets of test cases are generated to provide full code coverage.

D : An engine is provided that allows the user to execute the model.
