Question No. 1

Assume you have some data related to confirmation testing during system testing of a past project.

In that project 240 bug reports have been opened once, 80 were opened twice, 10 were opened three times and no bug reports have been opened more than three times.

You estimate that a bug report, which has failed its confirmation test, costs, on average, 3 personhours.

Which of the following statements correctly describe the value of these confirmatory testing activities based on cost of quality?

K3 2 credits

A300 person-hours have been spent on the project during the system testing phase, because of the failed confirmation tests and this cost belongs to the costs of internal failure

B340 person-hours have been spent on the project during the system testing phase, because of the failed confirmation tests and this cost belongs to the costs of external failure

C340 person-hours have been spent on the project during the system testing phase, because of the failed confirmation tests and this cost belongs to the costs of internal failure

D300 person-hours have been spent on the project during the system testing phase, because of the failed confirmation tests and this cost belongs to the costs of detection

Question No. 2

Which of the following statements about the STEP test process improvement model is true? K2 1 credit

AIn the STEP model, tests validate the requirements and use cases when they are developed

BThe STEP model stresses defect detection and demonstration of capability, whereas the defect prevention is a secondary potential goal of testing

CThe STEP model assures that the system requirements specification and the test design specification processes don't overlap

DIn the STEP model, testware design occurs after coding

Question No. 3

Which of the following statements describing the consequences of specifying test conditions at a detailed level is NOT true?

K2 1 credit

AIn an environment where the test basis is continuously changing, it is recommended to specify test conditions at a detailed level in order to achieve a better maintainability

BThe specification of test conditions at a detailed level can be effective when no formal requirements or other development work products are available

CThe specification of test conditions at a detailed level can require the implementation of an adequate level of formality across the team

DFor system testing, the specification of test conditions at a detailed level, carried out early in the project as soon as the test basis is established, can contribute to defect prevention

Correct Answer: A

Question No. 4

Assume you are working on a CAS (Conditional Access System) for Pay-TV that allows the access, selection and transfer of services and media to authorized users. Authorized users can choose their services through different channels: Web Customer Portal, IVR (Interactive Voice Response), Call Centre and SMS. The system uses a Smart Card to receive and decrypt the broadcasted encrypted control words which allow decrypting pay-per-view TV. Every authorized user must have a Smart Card and a Set-Top Box to view the contents.

The following is an excerpt from the product risk analysis document:

Both likelihood and impact have been rated on the following scale: (1 -- Very low, 2 -- Low, 3 --Medium, 4 -- High, 5 -- Very High).

The required test environment and code have been delivered. All test cases for each identified product risk item have been written and are ready to be executed. The Database used to contain the Smart Cards is empty and so only new Smart Cards can be used during test execution.

A Smart Card can only be activated if it has been previously pre-activated. This means the postconditions for the execution of the test cases to test the pre-activation of the Smart Card are the pre-conditions for activation of the Smart Card.

Which of the following statements represents the most effective contribution of the stakeholders to the completion of the failure mode analysis table?

K4 3 credits

AThe aircraft pilot and the customer representative should contribute to assess the detection. The chief software engineer, the system architect and the expert tester should contribute to assess the priority.

BThe aircraft pilot and the customer representative should contribute to assess the priority. The chief software engineer, the system architect and the expert tester should contribute to assess the detection.

CThe system architect and the chief software engineer should contribute to assess the priority. The expert tester is the only one who should contribute to assess the detection.

DThe aircraft pilot is the only one qualified to contribute to assess the priority and thus should be assigned this task. The customer representative should contribute to assess the detection.

Correct Answer: B

Question No. 5

Assume you are currently working on a project developing a system where functional

requirements are very well specified. Unfortunately non-functional requirements do almost not exist.

You are the Test Manager. You have to choose a technique for test selection that allows testing of non-functional characteristics, especially reliability.

Which of the following techniques for test selection do you expect being most useful in this scenario?

K2 1 credit

AA model-based technique based on the creation of operational profiles

BAmbiguity reviews

CTest condition analysis

DCause-effect graphing
