ISQI CTAL-TA_V4.0 Exam Syllabus Topics:

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

1. 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) Deterministic testing
C) Metamorphic testing
D) Property-based testing

2. You have been assigned as Test Analyst on a project that will deliver quotes for motor insurance. The amount quoted depends upon the combined values of twelve variables, that are resolved by a set of business rules.
What should be your MAIN task during the test analysis activity?

A) Identify additional tests based on lessons learned from earlier test execution activity
B) Identify the tests that should be executed against the current version of the test
C) Select or adapt existing test cases for use in subsequent regression testing
D) Use a test design technique to model the way in which the quote will be produced

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

4. You are defining test environment requirements for an online retail application that will have to handle high transaction volumes and uses a third-party payment authorization gateway.
Which requirement is MOST important for the functional testing?

A) The ability to simulate the real end-user experience
B) The ability to simulate the payment authorization gateway
C) The ability to support white-box test techniques
D) The ability to simulate peak production transaction volumes

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