Question 1

Which of the following statements about white-box testing is FALSE?

Options :

A : Static testing can benefit from using code-related white-box test techniques during code reviews.

B :

White-box testing allows suggesting test cases for increasing coverage levels which are based on objective measures

C : Achieving full code coverage for a component or a system ensures that it has been fully tested

D :

Black-box testing can benefit from using code-related white-box test techniques to increase confidence in the code.

Answer: C

Question 2

Which of the following statements about white-box test techniques is true?

Options :

A :

Achieving full statement coverage and full branch coverage for a software product means that such software product has been fully tested and there are no remaining bugs within the code

B :

Code-related white-box test techniques are not required to measure the actual code coverage achieved by black-box testing, as code coverage can be measured using the coverage criteria associated with black-box test techniques

C :

Branch coverage is the most thorough code-related white-box test technique, and therefore applicable standards prescribe achieving full branch coverage at the highest safety levels for safety-critical systems

D :

Code-related white-box test techniques provide an objective measure of coverage and can be used to complement black-box test techniques to increase confidence in the code

Answer: D

Question 3

Which of the following is a test task that usually occurs during test implementation?

Options :

A : Make sure the planned test environment is ready to be delivered

B : Find, analyze, and remove the causes of the failures highlighted by the tests

C : Archive the testware for use in future test projects

D : Gather the metrics that are used to guide the test project

Answer: A

Question 4

Which of the following statements is true?

Options :

A : A defect does not always produce a failure, while a bug always produces a failure

B : A defect may cause a failure which, when occurring, always causes an error

C : Failures can be caused by defects, but also by environmental conditions

D : Bugs are defects found during component testing, while failures are defects found at higher test levels

Answer: C

Question 5

For each test case to be executed, the following table specifies its dependencies and the required configuration of the test environment for running such test case:

Assume that C0NF1 is the initial configuration of the test environment Based on this assumption, which of the following is a test execution schedule that is compatible with the specified dependencies and allows minimising the number of switches between the different configurations of the test environment^

Options :

A : TC4, TC3, TC2, TC1, TC5.

B : TCI, TC5, TC4, TC3, TC2

C : TC4, TC3, TC2, TC5, TC1.

D : TC4, TC1, TC5, TC2, TC3
