ISQI ISTQB Certified Tester Advanced Level Test Analyst (CTAL-TA v4.0) Sample Questions:

Question 1

You are working on a project to build a purchasing system. The main requirements for the system are that it shall:
* Allow users to enter details of items that they wish to have purchased and, from these details, create a purchase request.
* Take each purchase request through a workflow that will allow the requestor's line manager to approve the request, reject it or return it for clarification / modification.
* Forward approved requests to the Purchasing Department.
* Allow purchasers to find the best available supplier for each approved request and place the request on that supplier as a purchase order.
The solution is being developed according to the company's traditional V-model methodology. The requirements are clearly documented and include a business process model. Operational profiles have been created to guide performance testing.
Initial item entry will involve a check that each item entered exists on the master stock file and that the user is entitled to request it; this depends on user role and grade. Line manager authorization will be assisted by a recommendation made by the system according to relevant business rules, although the manager can override this recommendation. For approved requests, the workflow will continue to support the process through to placing of the purchase order.
Planning has begun for system testing and the Test Manager has asked you, the senior TA, to help with it.
What would be the MOST effective techniques for functional testing of this project?
a) Combinatorial testing
b) Random testing
c) CRUD testing
d) State transition testing
e) Scenario-based testing
f) Decision table testing
g) Exploratory testing

A. a, b and g
B. c, e and g
C. d, e and f
D. b, d and f

Question 2

You are testing a program which should calculate the area of a trapezium and have decided to use metamorphic testing. The formula Area = (((a + b) / 2) * h) where a and b are the lengths of the two parallel sides, and h is the height when the parallel sides are horizontal.
Which ONE of the following would be an appropriate metamorphic relation?

A. If b increases by x% then area increases by ((x * 2) / 3)%
B. If b increases by x then h increases by ((x * 2) / 3)%
C. If b increases by x then area increases by ((x * 2) / 3)%
D. If b increases by x% then h increases by ((x * 2) / 3)%

Question 3

Your company, which specializes in medical software, has designed an application for use on smartphones and tablets that calculates a person's BMI, Body Mass Index.
How can a Test Analyst BEST contribute to interoperability testing for this application?

A. Verifying that the application integrates with the national health service system, receiving and processing the correct BMI data file
B. Verifying that the application works on all intended target smartphones and tablet devices and their operating systems
C. Verifying that users with disabilities can access their BMI effectively and efficiently using the application
D. Verifying that the application co-exists with other health applications on the target device without affecting their performance

Question 4

The following use case diagram shows the process of raising a Purchase Request (PR) and getting it authorized. Details are entered in batches; any that fail validation will be rejected and must be re-entered. The details will indicate whether the request is a normal one or an emergency one. Normal requests must be authorized by the department manager, who may refuse to do so. Emergency requests will be automatically authorized and reported to the manager.

The test strategy states that:
* all combinations of extensions and exceptions, as well as the main scenario, shall be tested
* loops shall get simple loop coverage where the maximum number of iterations for validation exceptions is 3 and the typical number is 2.
What is the minimum quantity of test cases that will be needed to obtain this coverage?

A. 5
B. 7
C. 4
D. 6

Question 5

You are developing test cases for an application which performs complex calculations and have decided to model these calculations on a spreadsheet, to determine expected results from inputs.
Which solution to the test oracle problem BEST describes the approach you are using?

A. A pseudo-oracle
B. Property-based testing
C. Deterministic testing
D. Metamorphic testing
