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

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

ISO/IEC 25010 defines two key quality models:

Product Quality Model (e.g., Usability, Security, Portability)

Quality in Use Model — which includes characteristics of the user’s experience when interacting with the product in a real-world context.

The four main characteristics of the Quality in Use model are:

Effectiveness

Efficiency

Satisfaction

Freedom from risk

Option A — Efficiency is one of the key Quality in Use characteristics, as it refers to the resources used to achieve goals with accuracy and completeness.

Other options:

B (Usability), C (Compatibility), and D (Portability) are characteristics of the Product Quality Model, not of Quality in Use.

Therefore, the correct answer, as per ISO 25010:2011, is:

Answer: A. Efficiency

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
