ISTQB CTFL v4.0 Practice Test 45

Question 440

During a release-readiness review, a tester observes: A test-plan review appoints only the author and project sponsor, so the plan omits integration prerequisites known to operations engineers. Which repeatable testing practice most directly reduces recurrence of this problem?

  1. Set practical work-product size and preparation guidelines.
  2. Add stakeholder mapping to review preparation for cross-system plans.
  3. Define review types and expectations before scheduling sessions.
  4. Combine static analysis with risk-selected dynamic test design.

Explanation

Correct Answer

B:

This safeguard specifically targets the contributing cause: Add stakeholder mapping to review preparation for cross-system plans. It addresses the principle (Review success depends on participant knowledge and coverage of affected concerns.) and can be assessed by: The plan includes the missing interface dependencies and realistic test environment requirements.

Incorrect Answers

A:

This preventive step mitigates a different project risk (syllabus section 3.2): A team holds a formal code review on a huge unbounded change set and reviewers overlook security errors after hours of fatigue. The targeted safeguard for the current case is: Add stakeholder mapping to review preparation for cross-system plans.

C:

This preventive step mitigates a different project risk (syllabus section 3.2): A senior developer leads a walkthrough of a design using examples but project staff insist it must be called an inspection because the author presents the material. The targeted safeguard for the current case is: Add stakeholder mapping to review preparation for cross-system plans.

D:

This preventive step mitigates a different project risk (syllabus section 3.1): A mobile banking team relies on a peer review to confirm fee arithmetic but never runs boundary tests for integer overflow. The targeted safeguard for the current case is: Add stakeholder mapping to review preparation for cross-system plans.

Question 441

A test analyst investigates the following quality concern: A team invites many external observers to an inspection while reviewers fear blame for raising defects and consequently report no problems. Which testing activity or corrective action best addresses this situation?

  1. Involve the relevant environment and operations stakeholders during planning review.
  2. Establish a psychologically safe defect-focused review process with neutral facilitation and confidentiality when appropriate.
  3. Ask participants to inspect the work product individually before collectively discussing and recording findings.
  4. Resolve the conflicting rules with stakeholders while the requirements are still editable.

Explanation

Correct Answer

B:

The targeted action is: Establish a psychologically safe defect-focused review process with neutral facilitation and confidentiality when appropriate. It addresses the underlying software-testing principle: A constructive collaborative climate is essential to credible review findings. The relevant confirming evidence is: Reviewers report genuine issues that are discussed without personal retaliation.

Incorrect Answers

A:

This choice is a useful response to a different testing situation (section 3.2, Feedback and Review Process): A test-plan review appoints only the author and project sponsor, so the plan omits integration prerequisites known to operations engineers. The present problem instead depends on: A constructive collaborative climate is essential to credible review findings.

C:

This choice is a useful response to a different testing situation (section 3.2, Feedback and Review Process): A team starts a code inspection with no individual preparation and expects defects to be found only during the live meeting. The present problem instead depends on: A constructive collaborative climate is essential to credible review findings.

D:

This choice is a useful response to a different testing situation (section 3.1, Static Testing Basics): A requirements group detects conflicting tax exemptions during inspection but delays correction until a regression suite can be executed weeks later. The present problem instead depends on: A constructive collaborative climate is essential to credible review findings.

Question 442

A test analyst investigates the following quality concern: A team invites many external observers to an inspection while reviewers fear blame for raising defects and consequently report no problems. Which observation best verifies that the stated testing issue is addressed?

  1. Findings focus on the required accessibility attributes and can be assigned for resolution.
  2. Reviewers report genuine issues that are discussed without personal retaliation.
  3. The omitted authorization case is added and the review issue is formally closed with evidence.
  4. Reviewers identify and remove the unsafe instruction even though the file always parsed successfully.

Explanation

Correct Answer

B:

This is the expected verification outcome: Reviewers report genuine issues that are discussed without personal retaliation. It directly checks the corrective activity (Establish a psychologically safe defect-focused review process with neutral facilitation and confidentiality when appropriate.) for the described testing problem.

Incorrect Answers

A:

This result may validate another testing scenario: A UX review meeting invites eight stakeholders but has no scope or entry criteria, so feedback debates branding without addressing the intended accessibility questions. It does not establish the required result for this case: Reviewers report genuine issues that are discussed without personal retaliation.

C:

This result may validate another testing scenario: A requirements walkthrough finds a serious omission, but the meeting ends with no person responsible for correction and the issue disappears. It does not establish the required result for this case: Reviewers report genuine issues that are discussed without personal retaliation.

D:

This result may validate another testing scenario: An AI chatbot team reviews an incident playbook only by running its JSON parser; it misses an unsafe instruction saying analysts may skip verification. It does not establish the required result for this case: Reviewers report genuine issues that are discussed without personal retaliation.

Question 443

A test analyst investigates the following quality concern: A team invites many external observers to an inspection while reviewers fear blame for raising defects and consequently report no problems. Which testing concept or underlying cause best explains the reported problem?

  1. Review completion requires a decision based on explicit acceptance or exit conditions.
  2. Review efficiency and defect detection suffer when review size and pace exceed human capacity.
  3. Early static feedback can prevent the propagation of defects into implementation and tests.
  4. A constructive collaborative climate is essential to credible review findings.

Explanation

Correct Answer

D:

The most relevant explanation is: A constructive collaborative climate is essential to credible review findings. This describes why the original situation (A team invites many external observers to an inspection while reviewers fear blame for raising defects and consequently report no problems.) merits the response: Establish a psychologically safe defect-focused review process with neutral facilitation and confidentiality when appropriate.

Incorrect Answers

A:

This principle could explain a different testing issue: A moderator closes a formal review because time is up although several blocking defects remain unresolved and no exit rule exists. The present case is better explained by: A constructive collaborative climate is essential to credible review findings.

B:

This principle could explain a different testing issue: A team holds a formal code review on a huge unbounded change set and reviewers overlook security errors after hours of fatigue. The present case is better explained by: A constructive collaborative climate is essential to credible review findings.

C:

This principle could explain a different testing issue: A requirements group detects conflicting tax exemptions during inspection but delays correction until a regression suite can be executed weeks later. The present case is better explained by: A constructive collaborative climate is essential to credible review findings.

Question 444

A test analyst investigates the following quality concern: A team invites many external observers to an inspection while reviewers fear blame for raising defects and consequently report no problems. Which repeatable testing practice most directly reduces recurrence of this problem?

  1. Select reviewers by relevant risk and required knowledge rather than availability alone.
  2. Use revision-aware comment systems and completion checklists.
  3. Coach moderators and managers on non-blaming issue resolution.
  4. Plan each technique around its strengths and foreseeable limits.

Explanation

Correct Answer

C:

This safeguard specifically targets the contributing cause: Coach moderators and managers on non-blaming issue resolution. It addresses the principle (A constructive collaborative climate is essential to credible review findings.) and can be assessed by: Reviewers report genuine issues that are discussed without personal retaliation.

Incorrect Answers

A:

This preventive step mitigates a different project risk (syllabus section 3.2): A complex security design is reviewed exclusively by frontend developers, and nobody checks the authorization assumptions behind the new data flow. The targeted safeguard for the current case is: Coach moderators and managers on non-blaming issue resolution.

B:

This preventive step mitigates a different project risk (syllabus section 3.2): A distributed review board receives comments after a deadline but cannot tell whether the author fixed the correct document revision. The targeted safeguard for the current case is: Coach moderators and managers on non-blaming issue resolution.

D:

This preventive step mitigates a different project risk (syllabus section 3.1): A team reviews an API design early but later sees dynamic load failures, so leadership decides static reviews have no value. The targeted safeguard for the current case is: Coach moderators and managers on non-blaming issue resolution.

Question 445

In a fictional application-delivery project, the team reports: A distributed review board receives comments after a deadline but cannot tell whether the author fixed the correct document revision. Which testing activity or corrective action best addresses this situation?

  1. Treat the author-led session as a walkthrough and match its informality and objectives to stakeholder needs.
  2. Record the reviewed version, each finding location, the correction revision and a follow-up verification.
  3. Define review scope, participants, criteria, and work product beforehand.
  4. Report static-analysis findings separately from dynamic statement or branch coverage measures.

Explanation

Correct Answer

B:

The targeted action is: Record the reviewed version, each finding location, the correction revision and a follow-up verification. It addresses the underlying software-testing principle: Review management depends on traceable findings and explicit follow-up across versions. The relevant confirming evidence is: Review evidence connects every major defect to a verified change in the intended baseline.

Incorrect Answers

A:

This choice is a useful response to a different testing situation (section 3.2, Feedback and Review Process): A senior developer leads a walkthrough of a design using examples but project staff insist it must be called an inspection because the author presents the material. The present problem instead depends on: Review management depends on traceable findings and explicit follow-up across versions.

C:

This choice is a useful response to a different testing situation (section 3.2, Feedback and Review Process): A UX review meeting invites eight stakeholders but has no scope or entry criteria, so feedback debates branding without addressing the intended accessibility questions. The present problem instead depends on: Review management depends on traceable findings and explicit follow-up across versions.

D:

This choice is a useful response to a different testing situation (section 3.1, Static Testing Basics): A build engineer reports success from a static linter and incorrectly claims that all implemented branches have been covered by tests. The present problem instead depends on: Review management depends on traceable findings and explicit follow-up across versions.

Question 446

In a fictional application-delivery project, the team reports: A distributed review board receives comments after a deadline but cannot tell whether the author fixed the correct document revision. Which observation best verifies that the stated testing issue is addressed?

  1. Findings are associated with one requirement revision and can be verified after correction.
  2. Review evidence connects every major defect to a verified change in the intended baseline.
  3. Reviewers detect the security concern in a scoped review with a documented outcome.
  4. A revised statement defines the response-time limit and supports precise performance tests.

Explanation

Correct Answer

B:

This is the expected verification outcome: Review evidence connects every major defect to a verified change in the intended baseline. It directly checks the corrective activity (Record the reviewed version, each finding location, the correction revision and a follow-up verification.) for the described testing problem.

Incorrect Answers

A:

This result may validate another testing scenario: A product manager edits requirements while a formal review is underway, causing reviewers to analyze different versions and duplicate defect reports. It does not establish the required result for this case: Review evidence connects every major defect to a verified change in the intended baseline.

C:

This result may validate another testing scenario: A team holds a formal code review on a huge unbounded change set and reviewers overlook security errors after hours of fatigue. It does not establish the required result for this case: Review evidence connects every major defect to a verified change in the intended baseline.

D:

This result may validate another testing scenario: A medical booking team waits until executable code exists to examine a requirement that says 'fast appointment confirmation', leaving the performance target ambiguous. It does not establish the required result for this case: Review evidence connects every major defect to a verified change in the intended baseline.

Question 447

In a fictional application-delivery project, the team reports: A distributed review board receives comments after a deadline but cannot tell whether the author fixed the correct document revision. Which testing concept or underlying cause best explains the reported problem?

  1. Review formality should be adapted to objectives and risk rather than maximized for every artifact.
  2. Review activities include defect communication and follow-up rather than only discussion.
  3. Review management depends on traceable findings and explicit follow-up across versions.
  4. Documents, designs and other work products are examinable through static testing even without executables.

Explanation

Correct Answer

C:

The most relevant explanation is: Review management depends on traceable findings and explicit follow-up across versions. This describes why the original situation (A distributed review board receives comments after a deadline but cannot tell whether the author fixed the correct document revision.) merits the response: Record the reviewed version, each finding location, the correction revision and a follow-up verification.

Incorrect Answers

A:

This principle could explain a different testing issue: A user interface proposal needs rapid input from several business roles, but the team demands a full formal inspection for each minor wording change. The present case is better explained by: Review management depends on traceable findings and explicit follow-up across versions.

B:

This principle could explain a different testing issue: A requirements walkthrough finds a serious omission, but the meeting ends with no person responsible for correction and the issue disappears. The present case is better explained by: Review management depends on traceable findings and explicit follow-up across versions.

D:

This principle could explain a different testing issue: A library website suffers repeated failures caused by a wrong API path specified in its interface design, and developers assume only dynamic tests can uncover that design error. The present case is better explained by: Review management depends on traceable findings and explicit follow-up across versions.

Question 448

In a fictional application-delivery project, the team reports: A distributed review board receives comments after a deadline but cannot tell whether the author fixed the correct document revision. Which repeatable testing practice most directly reduces recurrence of this problem?

  1. Review independence and role assignments for high-risk artifacts.
  2. Coach moderators and managers on non-blaming issue resolution.
  3. Use revision-aware comment systems and completion checklists.
  4. Maintain distinct metrics and qualified claims for inspection versus execution.

Explanation

Correct Answer

C:

This safeguard specifically targets the contributing cause: Use revision-aware comment systems and completion checklists. It addresses the principle (Review management depends on traceable findings and explicit follow-up across versions.) and can be assessed by: Review evidence connects every major defect to a verified change in the intended baseline.

Incorrect Answers

A:

This preventive step mitigates a different project risk (syllabus section 3.2): A safety-critical module requires an inspection, but the same developer authors, moderates, and individually approves all review findings without independent preparation. The targeted safeguard for the current case is: Use revision-aware comment systems and completion checklists.

B:

This preventive step mitigates a different project risk (syllabus section 3.2): A team invites many external observers to an inspection while reviewers fear blame for raising defects and consequently report no problems. The targeted safeguard for the current case is: Use revision-aware comment systems and completion checklists.

D:

This preventive step mitigates a different project risk (syllabus section 3.1): A build engineer reports success from a static linter and incorrectly claims that all implemented branches have been covered by tests. The targeted safeguard for the current case is: Use revision-aware comment systems and completion checklists.

Question 449

A tester is asked to evaluate the following situation: A team chooses randomized inputs for a shipping discount before reading the discount rule, then claims it has performed systematic specification-based test design. Which testing activity or corrective action best addresses this situation?

  1. Match test techniques to the work product: suitable partitions for search and decision tables for the eligibility logic.
  2. Derive test conditions from the rule and select a suitable black-box technique for discount ranges.
  3. Measure separately which requirement conditions and structural items are exercised by the tests.
  4. Execute the actual cancellation event and validate state and associated billing effects.

Explanation

Correct Answer

B:

The targeted action is: Derive test conditions from the rule and select a suitable black-box technique for discount ranges. It addresses the underlying software-testing principle: Black-box techniques derive tests from the specified behavior without needing code structure. The relevant confirming evidence is: Each documented discount class has a representative input with an expected total.

Incorrect Answers

A:

This choice is a useful response to a different testing situation (section 4.1, Test Techniques Overview): A team always selects decision tables for simple free-text search without constraints and reserves no method for a complex eligibility rule with multiple conditions. The present problem instead depends on: Black-box techniques derive tests from the specified behavior without needing code structure.

C:

This choice is a useful response to a different testing situation (section 4.1, Test Techniques Overview): A team treats automated test-count growth as proof that it has covered every requirement and structural path. The present problem instead depends on: Black-box techniques derive tests from the specified behavior without needing code structure.

D:

This choice is a useful response to a different testing situation (section 4.2, Black-Box Test Techniques): A music service supports Trial, Paid and Cancelled memberships, and its tests jump directly to Cancelled by setting database state, missing the cancellation event's side effects. The present problem instead depends on: Black-box techniques derive tests from the specified behavior without needing code structure.

Question 450

A tester is asked to evaluate the following situation: A team chooses randomized inputs for a shipping discount before reading the discount rule, then claims it has performed systematic specification-based test design. Which observation best verifies that the stated testing issue is addressed?

  1. Each documented discount class has a representative input with an expected total.
  2. The eligibility cases cover relevant combinations and the search uses representative text classes.
  3. The suite includes newly specified age limits plus failure patterns from previous releases.
  4. The report identifies actual executed statements and excludes unreachable or generated code according to stated rules.

Explanation

Correct Answer

A:

This is the expected verification outcome: Each documented discount class has a representative input with an expected total. It directly checks the corrective activity (Derive test conditions from the rule and select a suitable black-box technique for discount ranges.) for the described testing problem.

Incorrect Answers

B:

This result may validate another testing scenario: A team always selects decision tables for simple free-text search without constraints and reserves no method for a complex eligibility rule with multiple conditions. It does not establish the required result for this case: Each documented discount class has a representative input with an expected total.

C:

This result may validate another testing scenario: A tester relies on a checklist of historic outages and misses a newly required age boundary in a registration feature. It does not establish the required result for this case: Each documented discount class has a representative input with an expected total.

D:

This result may validate another testing scenario: A developer asserts 100% statement coverage can be established by inspecting the code without running any instrumentation or test execution. It does not establish the required result for this case: Each documented discount class has a representative input with an expected total.
