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

Collaboration between business analysts and testers is critical in Agile and acceptance testing environments. One of the most effective areas of cooperation is the joint development and review of acceptance criteria for user stories. This ensures that criteria are testable, clearly defined, and aligned with stakeholder expectations.

Option B is correct because creating acceptance criteria is where both business analysts (who understand the business needs) and testers (who ensure testability and clarity) contribute effectively.

Other options:

A (Business needs assessment) is typically a responsibility of business analysts, not a joint activity with testers.

C (Review of risk to prioritize acceptance tests) is a valuable activity but comes after criteria are defined. While it can be collaborative, it's more specific to test planning.

D (Definition of Beta Testing sessions) is less relevant to ongoing collaborative work between testers and BAs — this involves users and release planning.

Answer: B. Development of acceptance criteria for 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

Let’s analyze the DMN table shown in the image:

Rule 1: If weight ≤15, size ≤50, and distance ≤10 → use Normal bicycle

Rule 2: If weight is between 15 and 60 kg, size ≤150, and distance ≤25 → use Electric cargo bike

Rule 3: Otherwise → use Electric van

Now consider the options:

A: Incorrect — parcel size is not the only determining factor for using electric vans; it's about weight, size, and distance combined.

B: Incorrect — normal bicycles are used only when weight ≤15 kg, size ≤50 cm, and distance ≤10 km — so not just “short trips.”

C: Incorrect — electric cargo bikes are explicitly used for short trips (≤25 km), per Rule 2.

D: Correct — based on the rules, any weight above 15 kg (and up to 60 kg) results in the use of electric cargo bikes. So if weight >50 kg (but ≤60), cargo bike is still used under the conditions of Rule 2.

Therefore, the most consistent interpretation of the decision model is:

Answer: D. When the weight of the parcel exceeds 50kg then the electric cargo bike is necessarily used
