Non-functional quality attributes (also called quality characteristics) such as usability, reliability, operability, performance, and maintainability are often validated during acceptance testing to ensure the system behaves as expected under real-world conditions.

Option C is correct because operability — a subcharacteristic of usability per ISO 25010 — refers to the degree to which users can operate and control the system effectively. Acceptance testing often involves running the system in realistic settings to validate these aspects.

Other options:

A (Modularity and reusability) are more relevant to system architecture and design, not acceptance testing.

B is incorrect — time behavior (performance) can and should be tested at multiple levels, including system and integration testing before acceptance.

D is misleading — testing basic functionality is necessary, but it does not address non-functional quality attributes.

Answer: C. During acceptance testing, the operability of the product is checked in a realistic environment

An exploratory test charter is a high-level plan or mission statement for a time-boxed exploratory testing session. It guides what the tester should focus on during the session and may include the goal of the test, specific areas of the system under test, the risk or feature to explore, the type of persona to simulate (e.g., novice or expert user), and possibly known issues to watch out for.

Option A is correct because specifying a user persona (such as a novice user) helps the tester approach the system from that perspective. This supports the goal of exploratory testing: to simulate realistic usage and uncover issues that scripted tests might miss.

Option B is incorrect — although exploratory testing is adaptive, the charter is defined before the session starts, not elaborated during execution.

Option C is misleading — charters may refer to areas of interest, but not necessarily to a predefined list of activities.

Option D is incorrect — a test oracle (i.e., the mechanism for determining whether a result is correct) is not defined by the charter. It may exist already or be inferred from requirements, heuristics, or user expectations.

Exact Reference – ISTQB CTFL Acceptance Testing Syllabus (Section 3.1):

“Charters define the focus of exploratory testing sessions and may specify the tester’s role or perspective (e.g., novice user).”

Comprehensive Detailed Explanation (Approx. 200 words):

Acceptance criteria are an essential part of requirements engineering and test design. According to the ISTQB CTFL Acceptance Testing Syllabus, acceptance criteria are defined as a set of statements that specify what must be true for a system, feature, or user story to be considered acceptable to stakeholders. These criteria are used as the basis for developing acceptance test cases and help bridge the communication between stakeholders, business analysts, developers, and testers.

They are not exclusive to Agile frameworks (contrary to option A); while common in Agile (e.g., as part of a user story), they are equally valuable in traditional lifecycles. Option B is incorrect because testers are encouraged to collaborate in defining acceptance criteria early to ensure testability and clarity. Option C incorrectly states that acceptance criteria replace acceptance tests in ATDD (Acceptance Test-Driven Development). In fact, acceptance criteria are transformed into acceptance tests during ATDD.

Exact Reference – ISTQB CTFL Acceptance Testing Syllabus (Section 2.1):

“Acceptance criteria describe the conditions under which a requirement, user story, or business process is considered successfully implemented. They provide the foundation for acceptance testing and serve as input to test case development.”

Therefore, option D is the most accurate.

The medical scanner must be able to examine at least 50 patients per day. This requirement directly impacts hospital operations and service efficiency. If the scanner fails to meet performance requirements, such as processing speed or availability, it will affect the hospital’s ability to deliver services to patients — impacting schedules, patient flow, and ultimately the business goals of the hospital.

Option C is correct because it reflects the consequences of performance shortfalls from a business outcome perspective: failure to meet this requirement may result in financial loss, compliance issues, or customer dissatisfaction.

Other options:

A (User perspective) is involved, but the impact here is primarily operational/business.

B (Functional perspective) refers to whether the scanner has the correct features, not performance.

D (Technical perspective) is also relevant, but the business impact (e.g., service delivery) takes precedence in this case.

Answer: C. Business perspective

In Gherkin syntax (Given-When-Then), the purpose is to describe system behavior in a way that’s understandable to all stakeholders. Test steps should focus on user intentions and observable results — not UI implementation details — to ensure maintainability and abstraction.

Line 3 ("click 'Buy Tickets' button") refers explicitly to a UI element, which should generally be avoided in acceptance tests. Instead, it could say "I request to buy tickets."

Line 7 ("I should provide my personal data") is describing an action the user must take, not an outcome or result. In a Gherkin “Then” step, we expect an observable system response, not further user interaction.

Option C identifies both of these review concerns correctly.

Other options:

A includes an incorrect comment about line 4 ("quantity should not be set") — setting a value is acceptable.

B is false — the test case has reviewable issues.

D might be valid in a different context (e.g., boundary tests), but that’s not a flaw in the existing scenario.

Answer: C. Line 3 refers to an element of the user interface, which is to be avoided and line 7 is an action and not a result

Decision Model and Notation (DMN) is a standardized approach used to model decision logic, often represented in decision tables that evaluate inputs and determine outputs. In this scenario, the entitlements granted to a candidate are based on the total score from two exams, where:

Each exam can be graded as either 0 or 1.

The combined score can be 0, 1, or 2.

The entitlements depend on the combined result:

0 → No entitlements

1 → Partial entitlements

2 → Full entitlements

Among the given diagrams:

Option A simply lists test cases but lacks explicit logic modeling.

Option B shows a mapping from total score to entitlements but doesn't model how the total is derived from the two exams.

Option C redundantly splits outputs into multiple Boolean fields and doesn't reflect how the decision is made from exam inputs.

Option D is the correct representation.

Option D uses:

e1 and e2 as inputs for Exam #1 and Exam #2.

Result as the sum of e1 + e2.

A final Output mapped based on the Result:

0 → No

1 → Partial

2 → Full

This structure accurately follows the DMN standard by expressing inputs, a derived result, and the corresponding decision output, making Option D the correct and most complete decision model.

Exact Reference – ISTQB CTFL Acceptance Testing Syllabus (Section 2.3):

“Decision tables are commonly used to express business rules that determine outputs based on combinations of inputs. DMN formalizes this structure to support automated reasoning.”

An acceptance test summary report is a high-level document produced at the end of acceptance testing. It provides stakeholders (especially business owners and decision-makers) with essential information to determine whether the system meets the acceptance criteria and whether it is ready for release.

Option A is correct because understanding the residual risk — based on test results, open defects, and coverage — is critical for release decisions. The summary report includes test execution status, significant findings, defect summaries, and an overall risk assessment.

Other options:

B (technical details on defect fixes) belong more in defect or technical reports, not in the acceptance summary.

C (test strategy/design methods) are part of the test plan, not the summary report.

D (test procedure info) is operational detail, not suited for a high-level summary report.

Answer: A. Information to evaluate the level of risk for product release.

Usability testing involves evaluating a product by observing real users performing tasks. The “think-aloud” method is a cornerstone of qualitative usability testing. Test participants verbalize their thoughts while interacting with the system, revealing what they understand, find confusing, or expect. This method helps identify usability problems tied to user behavior and thought processes.

Option D is correct because it directly reflects this principle — walkthroughs and think-aloud sessions highlight pain points users face while performing tasks.

Other options:

A describes expert reviews but incorrectly attributes user insight, which is less direct.

B misunderstands biometrics — they measure physiological responses (e.g., stress, eye movement) but don’t explain behavior retrospectively.

C is incorrect — log files show user actions, but identifying "strong points" like visual attraction requires observation, not just logs.

Answer: D. Walkthrough and thinking aloud methods can indicate difficulties users experience with certain tasks.

The relationship between testing and requirements engineering is iterative and collaborative. According to ISTQB CTFL and IQBBA FL syllabi, test activities such as test analysis and test design involve reviewing and interpreting acceptance criteria to derive test conditions and test cases. During this process, testers may identify ambiguities, conflicts, or missing acceptance conditions. These insights often result in feedback to business analysts or stakeholders, leading to refinement or changes in the acceptance criteria to ensure clarity, completeness, and testability.

This iterative feedback loop is essential in both Agile and traditional lifecycles. Therefore, option D is correct. It reflects the dynamic interaction between requirements and test design, where improving one often improves the other.

Other options are incorrect:

Option A falsely assumes business analysts don’t engage in test design, while in practice, they collaborate closely with testers.

Option B incorrectly suggests that IQBBA and ISTQB lifecycles are mutually exclusive. In fact, they complement each other.

Option C is incorrect in sequencing. In reality, solution evaluation (IQBBA) follows test execution, not precedes it.

Exact Reference – ISTQB CTFL Acceptance Testing Syllabus (Section 1.3.2):

“During test analysis, inconsistencies or missing information in the acceptance criteria can be identified and addressed through collaboration with business analysts.”

==================

Bi-directional traceability is a fundamental concept in requirements engineering and test management. It refers to the ability to trace:

Forward: From requirements/user stories to corresponding test cases (to ensure all requirements are covered).

Backward: From test cases to the requirements they validate (to ensure every test aligns with a requirement).

According to the ISTQB Certified Tester Foundation Level and Acceptance Testing syllabi, bi-directional traceability is essential to manage test coverage and ensure completeness. It allows project managers and product owners to assess whether all specified requirements/user stories have been covered by appropriate test cases, helping to identify any untested functionality.

This also supports impact analysis during change management — knowing which test cases will be affected by a change in a requirement.

Option B is correct because it precisely captures this benefit. While Option C refers to reviewing test cases against acceptance criteria (a valid review activity), the bi-directional traceability's key benefit from a management and quality assurance perspective is traceability for coverage.
