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

Beta testing is a form of external user acceptance testing where real users test the product in their environment before the official release. It helps identify issues that may not have been caught in internal testing and gather user feedback on functionality, usability, and performance in real-world conditions.

Option C is correct — the core goal of beta testing is to obtain user feedback in their actual usage context, providing insight into how the system performs outside of controlled environments.

Other options:

A: Test charters are used in exploratory testing, not typically in beta testing.

B: Incorrect — beta testing is not tied to the timing of user story development in Agile.

D: Incorrect — beta testing is performed by end users, not by internal team members like developers or business analysts.

Answer: C. Beta testing aims to obtain feedback from users in their context of use

Comprehensive Detailed Explanation (Approx. 200 words):

Acceptance criteria should focus on business-relevant outcomes that are specific, testable, and observable. In this user story, the goal is to validate that the registration functionality is available and behaves as expected.

Let's analyze each proposition:

i) “A registration form is displayed on the screen.”

→ Valid. It is observable, specific, and directly aligned with the user story.

ii) “The form is written in the Groovy language; the cursor is initially set on the ‘login’ field...”

→ Invalid as acceptance criteria. It contains implementation details (e.g., “Groovy language”) irrelevant to business stakeholders. Also, low-level UI behavior like cursor position is overly technical and not a business-driven criterion.

iii) “I cannot register myself if the login I choose is used by another player.”

→ Valid. It defines system behavior based on a business rule (unique login) and is testable.

iv) “After successful registration process I am informed about it by an e-mail.”

→ Valid. It describes a user-visible outcome after registration, which is observable and testable.

Correct answer: D. only i), iii), and iv) are well-written acceptance criteria.

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

“Acceptance criteria must describe the externally visible and verifiable system behavior, excluding implementation details.”

Acceptance Test-Driven Development (ATDD) involves early collaboration between stakeholders to define acceptance criteria and tests before development begins. Using business process models in ATDD helps visualize user behavior, align test cases with real workflows, and serve as living documentation.

Option C is the least meaningful argument because:

Business process models abstractly describe workflows and decisions at a business level. While they help clarify requirements and detect requirement-related defects, they do not directly support detecting defects in the application code, which is typically the focus of unit and integration testing, not acceptance testing.

Let’s validate the other options:

A is a strong argument — process models clarify use cases for testers.

B is valid — graphical models help visualize test coverage directly.

D is true — as business process models evolve, they remain valuable artifacts aligned with current system behavior and requirements.

Answer: C. Business process models will make it easier to detect defects in the application code.
