CTFL-AcT Exam Dumps : ISTQB Certified Tester - Acceptance Testing (CT-AcT)

Traceability is a key principle in requirements and test management. It ensures that all features, requirements, and tests are linked and accounted for. Including traceability to user stories in BPMN diagrams or DMN tables supports transparency, auditability, and maintenance.

Option B is correct because embedding or referencing traceability information within business models improves communication across stakeholders, ensures proper test coverage, and helps during change impact analysis.

Let’s evaluate other options:

Option A is incorrect. Trying to place all model elements in one diagram can lead to cluttered and unreadable models.

Option C is misleading. While separation of concerns is useful, traceability (links to requirements, risks) should be integrated or closely accessible from the models.

Option D is incorrect. Acceptance testers should be involved early to collaborate and review models. Waiting until models are finalized contradicts agile and ATDD principles.

Answer: B. BPMN diagrams and DMN tables should include information such as traceability to user stories.

Exploratory testing is an unscripted, experience-based testing technique where the tester learns about the system, designs tests, and executes them simultaneously. It is especially effective in Agile environments, where rapid feedback and creative exploration are valuable.

Option D is the least likely action because scripting automated test scripts is a structured activity that typically occurs after exploratory sessions or during more formal test phases. Exploratory testing emphasizes manual exploration, not automation scripting.

Other options:

A is part of the core purpose of exploratory testing — discovering the product.

B is relevant — defining a charter and discussing it with stakeholders (like the Product Owner) helps guide the exploratory session.

C is also relevant — results of exploratory tests should be documented and communicated.

Answer: D. Scripting of the automated test scripts

This user story is about a logged-in user measuring their blood sugar using a connected glucose meter and seeing the result quickly. The acceptance criterion specifies that the result should be displayed in less than four seconds.

Option B is correct because:

It starts with a valid GIVEN precondition (“I am logged in”).

The WHEN step matches the functionality described in the user story (blood sugar measurement using a connected device).

The THEN step explicitly includes the performance expectation (“less than 4 seconds”), aligning directly with the acceptance criterion.

Other options:

A is incorrect — while it mentions the correct functionality, “I am diabetic” is not a necessary system precondition.

C refers to blood pressure instead of blood sugar — mismatched with the user story.

D introduces additional functionality (alerts for hypo-/hyperglycemia), which is not part of the specified acceptance criteria.

Answer: B. GIVEN I am logged in on the system … THEN I can see the result … in less than 4 second
