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

1. In which of the following circumstances is the transition from a high-level test case to a low-level test case MOST LIKELY to be deferred from test design to test implementation?

A) When the person who runs the test will not be its author
B) When product risk analysis has not been completed
C) When specific test data are needed for the test case
D) When the details required depend on the test execution schedule

2. A simple drinks machine is described in the following state transition diagram:

How many test cases will be needed for Chow's 1-switch coverage?

A) 19
B) 40
C) 28
D) 23

3. You are testing a program which calculates the best airspeed for optimal fuel economy of a new type of aero engine. The result depends on atmospheric pressure at the airplane's current height, the air temperature at the airplane's current height, and on the airplane's current fuel load. The best airspeed:
* decreases by 4 knots (nautical miles per hour) for every 5mb (millibar) decrease in atmospheric pressure,
* increases by 6 knots for every 1°C decrease in air temperature,
* increases by 1 knot for every 1,000kg decrease in fuel load.
You have a test case which predicts that at an atmospheric pressure of 1,000 mb, an air temperature of 10°C and a fuel load of 400,000kg, the optimal airspeed for an Airbus A380 is 600 knots.
Which test case would verify the metamorphic relation described in the three bullet points above?

A) Pressure 950mb, temp. 9°C, fuel 350,000kg, optimal airspeed = 616 knots
B) Pressure 950mb, temp. 10°C, fuel 360,000kg, optimal airspeed = 620 knots
C) Pressure 950mb, temp. 11°C, fuel 400,000kg, optimal airspeed = 610 knots
D) Pressure 1050mb, temp. 9°C, fuel 350,000kg, optimal airspeed = 590 knots

4. A system will be developed to support the administration of table-tennis tournaments. The following requirements for the enrolment of entrants have been provided:
R1. High. The administrator shall be able to enter the entrant's name, address, phone number/s (mobile and/or home), email and social media handles. Validation rules for these data items are provided separately.
R2. High. The administrator shall be able to enter the entrant's current world ranking (up to 250) and their relationship with the tournament sponsors (i.e. clothing / equipment / endorsement).
R3. High. The administrator shall be able to enter the entrant's attendance history at previous events (i.e.
finalist / played / withdrew during event / withdrew before event).
R4. Medium. From the entrant's address the system shall derive whether or not the entrant lives locally and, on the basis of that combined with other rules that are provided separately, shall suggest how much of the tournament's overall prize fund should be offered to the entrant as their individual attendance fee.
R5. Low. The administrator should be able to change the suggested attendance fee and the system should then deduct this from the remaining prize fund balance accordingly.
You have been asked to review the requirements using perspective-based reading, from your viewpoint as the TA who will be writing functional correctness system test cases. Assume that the other rules referred to by requirements R1 and R4 have been reviewed and are satisfactorily testable. Which conclusion would you reach?

A) All of the requirements are fully testable
B) One of the requirements is not fully testable
C) Three of the requirements are not fully testable
D) Two of the requirements are not fully testable

5. You are working on a project to build an application that will handle insurance claims. The main requirements for the system are that it shall:
* Allow users to enter details of claims that have been submitted by insured customers.
* Take each claim through a workflow that will allow an assessor to approve the request, reject it or request clarification from the claimant.
* Send approved requests to the accounts payable system for payment.
The solution is being developed according to the company's standard V-model methodology. The requirements are clearly documented and include a business process model. Operational profiles have been created to guide performance testing.
A risk-based approach to testing is used; frequency of use and role of the user are major factors in feature risk assessment.
System testing has almost finished but a major change to the approval workflow is just about to be delivered.
A standard regression test pack has not yet been established, but ad-hoc regression testing has already been performed on earlier builds.
As a TA. you have updated the list of product risks and must now decide the scope of the regression testing.
Which pair of techniques will be MOST effective for selecting the regression tests?
a) History-based, driven by the results of the regression tests run so far b) Risk-based, driven by the updated list of product risks and its traceability to the tests c) Operational profile-based, driven by the likely patterns of use of the relevant transactions d) Requirement traceability matrix-based, driven by the links from affected requirements to related tests e) Impact analysis, driven by consultation with technical stakeholders to identify what might be affected.

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