CTFL_Syll_4.0 Exam Dumps : ISTQB Certified Tester Foundation Level (CTFL) v4.0

Comprehensive and Detailed Explanation From Exact Extract:

From the user story analysis and final achievements:

It was confirmed that dues were paid monthly for over a year, whichcovers criteria 1, 2, 3, 5, 6, 7, and 8.

However, there isno mention of testing for “annual payment”, soacceptance criteria 4, which involveschoosing between monthly or annualpayment, wasnot fully tested.

This reflects the requirement stated in:

“Acceptance criteria are used to: Define the scope… Describe both positive and negative scenarios… Serve as a basis for the user story acceptance testing.”

(ISTQB CTFL Syllabus v4.0, Section 4.5.2, Page 45)

Product risksare risks thatimpact the quality or functionality of the software, whereasproject risksaffect theprocess, resources, or timeline.

(A) is correctbecause incorrect calculations impact software correctness.

(B), (C), and (D) are project risksas they relate toteam coordination, staffing, and schedulingrather than software defects.

Identifyingproduct risksearlyimproves defect detection and ensures better coverage for high-risk areas.

White-box testing, also known as structural testing, involves testing the internal structures or workings of an application, as opposed to its functionality (which is tested by black-box testing). The correct statement about white-box testing is that it helps find defects by measuring aspects such as statement coverage.

Statement Coverage: White-box testing techniques like statement coverage measure whether each statement in the code has been executed at least once. This helps ensure that all parts of the code are tested and can reveal defects in areas that might not be reached by black-box testing alone​​.

Other statements are less accurate in the context of white-box testing:

Specifications being vague: White-box testing is code-focused, not requirement-focused. If specifications are vague, it affects both white-box and black-box testing. The main advantage of white-box testing is that it allows testers to create tests based on the code's structure and logic​​.

Requirements-based coverage: This is typically associated with black-box testing, which derives tests from specifications and requirements. White-box testing, on the other hand, derives tests from the code itself​​.

Focus on defects rather than failures: Both white-box and black-box testing aim to identify defects, but white-box testing does this through code coverage and examining the code paths directly. It does not focus exclusively on defects rather than failures; it is just another method to identify potential issues​​.
