ISTQB Certified Tester Advanced Level Technical Test Analyst Sample Questions:

1. A project to replace your company's sales and merchandising system has begun. The old system is still in production but is poorly documented and expensive to maintain: changing it has often produced a large quantity of defects. The new version will be developed using modern techniques and technology.
Requirements include:
* Loading sales data, sent electronically from the stores each evening, into a central database where it is then available for other applications.
* Producing sales reports for the merchandisers, whose job is to manage stock levels in stores.
* Predictions of future demand for each product, based on a combination of sales history and forecasting parameters.
Requirements 1 and 2 are satisfied by the existing system and will be rewritten with no significant changes.
Requirement 3 is new: these forecasting reports will be run overnight, and users will request them by entering simple parameters online during the day.
The sales data are loaded in an overnight batch run. There have been problems at peak periods when this run has taken longer than scheduled, so that dependent jobs could not finish before the start of the working day.
As a Technical Test Analyst, you have been asked to contribute to the project's Master Test Plan. The key stakeholders are:
* The Merchandising Manager, who wants parameter entry to be quick and easy.
* The Data Centre Manager, who requires the new batch jobs to take less time than the old ones.
No specific performance requirements have been given, either for the batch jobs or for online parameter entry.
Which TWO of the following will BEST meet the objectives of the stakeholders?

A) Agree acceptance criteria for performance of the forecasting report parameter data entry features, based on operational profile models.
B) Conduct performance testing on the forecasting report parameter data entry features, in parallel with functional system testing.
C) Agree acceptance criteria for modifiability, modularity, and reusability, and measure these for change requests implemented after development begins.
D) Agree acceptance criteria for performance of the data load and report creation, based on a quantified improvement over the current system.
E) Conduct performance testing on the data load and report creation, in parallel with functional system testing.

2. Given the following pseudocode:
Program tax check
Integer: tax_rate
real: tax%
BEGIN
tax% := 0
GET (tax_rate)
WHILE tax_rate > 0 loop
IF tax_rate > 3 THEN
tax_rate := 3
ENDIF
tax% := tax% + (tax_rate / 10)
tax_rate := tax_rate - 1
ENDLOOP
IF tax% > 0.6 THEN
print ("tax rate is high")
ELSEIF tax% < 0.1 THEN
print ("tax rate is zero")
ELSE
print ("tax rate is low")
ENDIF
END tax check
If control flow analysis is performed on the pseudocode, which of the following results is MOST likely?

A) No unreachable code
B) Infinite loop from line 7 to line 13
C) Unreachable code at line 17
D) Unreachable code at line 15

3. As Technical Test Analyst on a test automation project covering the acquisition of a commercial test execution tool, what would you MOST likely be responsible for?

A) Approving the estimated costs for implementing the test automation project
B) Defining the business processes that will be used for keyword-driven testing
C) Determining who will execute the automated tests
D) Creating and supplying the data to be accessed by keyword-driven automation scripts

4. A review of the following pseudo code is to be performed using a checklist:
Module Vowel Counter
Message: array of Characters
M, N: Integer
ACount, ECount, ICount, OCount, UCount: Integer
BEGIN
I=1
Read Nextchar
While Nextchar <> 'S'
DO
Message (I) = Nextchar
I = I+1
Read Nextchar
ENDWHILE
FOR M = 1 To I
DO
Print (Message(M))
IF Message (M) = 'E'
THEN
ECount = ECount + 1
ELSE
IF Message (M) = 'A'
THEN
ACount = ACount + 1
ELSE
IF Message (M) = 'I'
THEN
ICount = ICount + 1
ELSE
IF Message (M) = 'O'
THEN
OCount = OCount + 1
ELSE
IF Message (M) = 'U'
THEN
UCount = UCount + 1
ENDIF
ENDIF
ENDIF
ENDIF
ENDIF
ENDFOR
Print ('Message contains ' ACount + ECount + ICount + OCount + UCount ' vowels') END Which of the following checklist items would find code errors in this scenario?
A) Are all variables properly declared?
B) Are all loops, branches, and logic constructs complete, correct, and properly nested?
C) Are all cases covered in an IF-ELSEIF, including ELSE or DEFAULT clauses?
D) Are loop termination conditions obvious and invariably achievable?
E) Are there any redundant or unused variables?

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