Free BCS CTFL4 Exam Questions

Question 1

Which ONE of the following elements is TYPICALLY used to guide testing during exploratory testing?

A : A test charter that defines the testing objectives for the test session.

B : A comprehensive specification that must be fully available before testing begins.

C : A detailed test script that prescribes all the steps to be performed.

D : A predefined test case that must be executed exactly as documented.

Answer: A

Question 2

Confirmation testing is performed after:

A : a defect is fixed and after other tests do not find any side-effect introduced in the software as a result of such fix

B : a failed test, and aims to run that test again to confirm that the same behavior still occurs and thus appears to be reproducible

C : the execution of an automated regression test suite to confirm the absence of false positives in the test results

D : Therefore, as a functional tester, you have the responsibility to report the performance issue as a defect, and provide as much information as possible to help the developers or the performance testers to investigate and resolve it. Question #:79 Which of the following statements about white-box test techniques is true? 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 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 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 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 Explanation This answer is correct because code-related white-box test techniques are test design techniques that use the structure of the code to derive test cases. They provide an objective measure of coverage, such as statement coverage, branch coverage, or path coverage, which indicate how much of the code has been exercised by the test cases. Code-related white-box test techniques can be used to complement black-box test techniques, which are test design techniques that use the functional or non-functional requirements of the system or component to derive test cases. By combining both types of techniques, testers can increase their confidence in the code and find more defects.

Answer: D

Question 3

Consider the following table, which contains information about test cases from the test management system:Which ONE of the following optionsorganizes the test cases based on the statement coverage strategy, while considering practical constraints?

A : {TC 20; TC 30; TC 10; TC 40; TC 50; TC 70; TC 60; TC 80; TC 90}

B : {TC 10; TC 30; TC 20; TC 60; TC 40; TC 80; TC 90; TC 50; TC 70}

C : {TC 80; TC 70; TC 50; TC 60; TC 20; TC 30; TC 10; TC 40; TC 90}

D : {TC 60; TC 80; TC 40; TC 90; TC 50; TC 10; TC 70; TC 30; TC 20}

Answer: D
