ISTQB Certified Tester Advanced Level Technical Test Analyst Sample Questions:

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?

A) Line 14: Cruise_Credits is re-defined before being used Line 27: Loyalty_Rating is defined but not subsequently used
B) Line 14: Cruise_Credits is not assigned a value (defined) before being used Line 27: Loyalty_Rating is defined but not subsequently used
C) Line 14: Cruise_Credits should not be declared as an integer Line 27: Loyalty_Rating should be calculated within the While loop
D) Line 14: Cruise_Credits is defined but not subsequently used Line 27: Loyalty_Rating is not assigned a value (defined) before being used

2. Which TWO of the following could be identified using Dynamic Analysis?
A) Objects having too much or too little visibility into parent classes.
B) Repetition of code within a single component or module.
C) System memory not released when it is no longer needed.
D) Pointers in a program that are no longer accurate and must not be used. E. Code that cannot be reached and so will not be executed.

A) a and b
B) a and c
C) d and e
D) c and d

3. Which statement is correct with respect to fault injection tools?

A) They modify the code under test in order to check the coverage achieved by specified tests
B) They can detect memory leaks and wild pointers when a component is executing
C) They inject defects into the SUT in order to test the error handling capabilities of test automation software
D) They deliberately introduce incorrect inputs to a system to ensure it can withstand and recover from error conditions

4. Which of the following statements about performance testing tools is NOT correct?

A) Typical metrics and reports provided by performance testing tools include the number of simulated users throughout the test, and the number and type of transactions generated by the simulated users, and the arrival rate of the transactions.
B) Performance testing tools typically drive the application by simulating user interaction at the graphical user interface level to more accurately measure response times.
C) Performance testing tools generate a load by simulating a large number of virtual users following their designated operational profiles to generate specific volumes of input data.
D) Significant factors to consider in the implementation of performance testing tools include the flexibility of the tool to allow different operational profiles to be easily implemented, and the hardware and network bandwidth required to generate the load.

5. Below is the pseudo-code for the bingo program:

The bingo program contains a data flow anomaly. Which data flow anomaly can be found in this program?

A) An invalid value is assigned to variable "B".
B) Variable "AB is defined but subsequently not used.
C) Variable "MIN" is not assigned a value before using it.
D) The hard-coded value '2" should not be used.
