Equivalence Partitioning (EP) is a black-box test design technique that divides input data into valid and invalid partitions, where each partition is expected to exhibit similar behavior. In the context of acceptance testing, EP is especially effective because it helps validate whether a system behaves correctly for representative input ranges defined in the acceptance criteria.

Acceptance testing aims to confirm that the system meets business requirements and handles inputs as expected. EP allows the tester to cover a large input space using fewer test cases while maintaining a high level of effectiveness. It supports efficiency, broad coverage, and relevance to user expectations.

Other options are less suitable:

A. Static code analysis is a white-box technique, more relevant to unit or integration testing.

B. Input validation is an objective or activity, not a test design technique.

D. Defect-based testing is more diagnostic, used after failures or during exploratory testing — less structured for planned acceptance testing.

Exact Reference – ISTQB CTFL Acceptance Testing Syllabus (Section 2.4):

“Black-box techniques such as equivalence partitioning and boundary value analysis are suitable for deriving acceptance tests from user stories or business rules.”

Beta testing is a type of external user acceptance testing performed by potential or existing customers in a real-world environment. It typically occurs after internal validation and acceptance tests have been passed. The purpose is to validate the product in realistic contexts, identify usability issues, uncover defects that may have been missed in lab settings, and gather feedback for improvements.

Option C is correct because it best describes the intent and value of beta testing — to observe how the product performs in real-life configurations, which may include varying hardware, usage patterns, or business workflows.

Option A is incorrect — while some people use the terms loosely, beta testing is not a strict synonym for acceptance testing. Acceptance testing usually refers to more formal, criteria-driven testing (e.g., alpha or internal acceptance testing), while beta testing emphasizes broad, usage-based validation.

Option B is misleading — beta testers may follow scenarios, but beta testing is not typically based on predefined acceptance criteria alone. It emphasizes exploration in realistic use cases.

Option D is false — beta testing is not primarily about measuring test coverage. It is qualitative and feedback-driven rather than systematically structured.

Exact Reference – ISTQB CTFL Acceptance Testing Syllabus (Section 3.2):

“Beta testing is performed by users in their own environment and supports validation of the system in realistic operational conditions.”

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

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.

User Experience (UX) requirement analysis is a critical component of acceptance testing and product development. According to ISTQB Acceptance Testing syllabus and industry-aligned UX design methodologies (e.g., ISO 9241-210 and BABOK guidelines), UX requirement analysis is typically structured around the following pillars:

User Analysis – Understanding who the users are (roles, goals, experience levels)

Task Analysis – Understanding what users do (tasks, workflows, pain points)

Context Analysis – Understanding where and how users interact with the product (environmental and contextual factors)

Competitor Analysis – Understanding how similar problems are solved in the market

Option B best describes Task Analysis, one of the most practical and impactful pillars. In task analysis, business analysts and UX researchers observe how users interact with current or comparable systems to understand workflow patterns, user frustrations, needs, and required system functionality. This method helps uncover implicit needs that users may not articulate in interviews.

This approach is aligned with ISTQB’s emphasis on understanding real-world usage and business processes as a foundation for deriving acceptance criteria and tests. It supports the creation of realistic scenarios that reflect actual user behavior, which is essential for verifying system fitness for use.

The other options are inaccurate:

A refers to psychological disposition, which is more aligned with user profiling or persona development, not a core focus of user analysis in requirement engineering.

C incorrectly ties context analysis with deriving security requirements, which is not its purpose.

D describes an unrealistic or incorrect method for competitor analysis.

Therefore, Option B is the best description of a key pillar of UX requirement analysis per industry and ISTQB standards.

This question is about combining Business Process Model and Notation (BPMN) and Decision Model and Notation (DMN) to design test cases for acceptance testing. The BPMN diagram outlines the customer checkout flow with a decision on whether a loyalty card is used, followed by a card scan that may trigger a discount check. The DMN decision table defines the logic for determining the discount percentage based on the number of loyalty points.

From the DMN:

<1000 points ⇒ 0% discount

1000–3000 points ⇒ 5% discount

3000 points ⇒ 5% discount

Option D correctly states that a customer with more than 500 points could be eligible for a 5% discount — but only if the number of points exceeds 1000. Since 500 does not meet the 1000 threshold, it appears this statement could be problematic at first glance. However, interpreting the spirit of the question, Option D is the only one matching the correct maximum discount scenario.

Let’s clarify each option:

A is incorrect: >1000 points qualifies for 5%, not 0%.

B is incorrect: 3% is not defined anywhere — DMN has 0% or 5%.

C is incorrect: again, 3% does not exist in the table.

D is acceptable in principle, assuming a typo (i.e., it should be “more than 1000” instead of 500); however, if taken literally, it would be incorrect.

However, given the options, D is the only one aligning with actual DMN output for >1000 loyalty points, despite the inaccurate lower limit.

Answer: D. These models can be used to generate a test case for a 5% reduction if the customer has more than 500 loyalty points

(If the literal error in Option D is to be treated strictly, the correct answer would be “none of the above,” but in context of typical ISTQB-style questions, D is the best fit.)

Comprehensive Detailed Explanation:

According to the scenario described in the question, the business process for expense reimbursement includes two key timing constraints:

If the request is not processed within 7 days, an "ongoing" email is sent to the employee.

If the request is not completed within 30 days, the process is canceled and the employee is asked to resubmit the request.

However, in the BPMN model presented in the image, the second timing event (clock icon near "Approval in Progress") incorrectly shows 23 days instead of 30 days. This discrepancy misrepresents the actual business rule and violates the accuracy required in process modeling.

ISTQB Foundation Level Extension – Acceptance Testing syllabus and the Certified Tester Foundation Level Business Process Testing (CTFL-BAT) emphasize that a process model should correctly reflect the specified behavior, rules, and constraints of the business scenario. An incorrect timer can lead to miscommunication between stakeholders and incorrect automation or implementation logic.

Therefore, Option A is the most likely review comment since it directly points to this inconsistency in the model.

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

In Gherkin syntax (Given-When-Then), the purpose is to describe system behavior in a way that’s understandable to all stakeholders. Test steps should focus on user intentions and observable results — not UI implementation details — to ensure maintainability and abstraction.

Line 3 ("click 'Buy Tickets' button") refers explicitly to a UI element, which should generally be avoided in acceptance tests. Instead, it could say "I request to buy tickets."

Line 7 ("I should provide my personal data") is describing an action the user must take, not an outcome or result. In a Gherkin “Then” step, we expect an observable system response, not further user interaction.

Option C identifies both of these review concerns correctly.

Other options:

A includes an incorrect comment about line 4 ("quantity should not be set") — setting a value is acceptable.

B is false — the test case has reviewable issues.

D might be valid in a different context (e.g., boundary tests), but that’s not a flaw in the existing scenario.

Answer: C. Line 3 refers to an element of the user interface, which is to be avoided and line 7 is an action and not a result

In situations where a team is demotivated or struggling with vision and direction, it's effective to use visualization workshops that help the team reflect on progress and visualize a path forward.

Option B describes a metaphorical workshop using a staircase to represent the project's journey — this is known as the "Stairway Retrospective" or "Timeline Workshop". It provides a shared mental model, identifies milestones, and encourages discussion around past progress and future steps. It's ideal for reigniting motivation and clarifying direction — which aligns with the issue described in the question.

Other options:

A can spark debate but may not be constructive or motivating in a stagnation scenario.

C may foster team bonding but doesn’t directly address project direction or vision.

D focuses only on future milestones and lacks the reflective component essential when a team feels stuck.

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

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.

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

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

Effective test reporting should be tailored to the audience’s role and needs. Project managers are typically concerned with high-level progress, schedules, risks, and milestones. Progress trend charts (e.g., test execution over time, defect trends) provide insights into how the project is advancing and help identify delays or bottlenecks.

Option B is correct as it fits the informational needs of a project manager.

Other options:

A: Defect reports are too detailed for steering groups, which prefer strategic summaries or risk reports.

C: Pie charts may provide high-level summaries, but development teams usually need detailed defect or test result data.

D: System users (e.g., customers) are not responsible for project risks and would not benefit from test risk rankings.

Answer: B. Progress trend charts for the project manager

Security requirements specify how a system should handle access control, data protection, confidentiality, integrity, and authentication. In acceptance testing, validating that users cannot access data or functions they are not authorized for is a critical test objective when dealing with security.

Option D is correct because it directly relates to access control — a fundamental aspect of security. Ensuring that “normal users shall have restricted access to private data” reflects both a security requirement and a condition that must be tested for compliance.

Other options:

A relates to performance (response time).

B refers to architecture or platform (web-based system).

C is about UI design and usability (style compliance).

Only D addresses security specifically.

Answer: D. Normal users shall have restricted access to private data.

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.”

Performance testing assesses how a system behaves under specific conditions, typically focusing on responsiveness, stability, and resource usage. The type of performance test depends on the workload model:

Load testing evaluates performance under expected peak usage.

Stress testing pushes the system beyond its capacity to assess limits.

Endurance/stability testing checks for performance degradation over extended periods.

Option A correctly describes that performance test types are determined by the workload simulation strategy.

Other options:

B confuses performance with security testing — malicious attack robustness is a security focus, not performance.

C is partly correct but less comprehensive than A. While testing should simulate realistic conditions, categorization into stress/load/endurance is better aligned with workload modeling.

D is misleading — performance tests validate systems against performance requirements; they are not primarily used to define them.

Answer: A. Depending on the model used to simulate the workload, performance tests are called load, stress or endurance / stability tests.

The goal here is to achieve full decision coverage (also known as branch coverage), which means each decision point in the process must evaluate to both TRUE and FALSE at least once during testing.

From the BPMN ATM withdrawal model, we identify two key decisions:

Is the balance ≥ $100?

If yes, is receipt = YES?

To achieve full decision coverage:

One test must evaluate decision 1 as TRUE and another as FALSE.

If decision 1 is TRUE, then decision 2 must be exercised both ways (receipt = YES and NO), but for minimal decision coverage, one path through decision 2 is enough.

Analyzing test cases:

Test 1 (balance = $100, receipt = YES): decision 1 = TRUE, decision 2 = TRUE

Test 2 (balance = $99): decision 1 = FALSE

These two tests ensure:

Decision 1 evaluated TRUE (Test 1) and FALSE (Test 2)

Decision 2 evaluated at least once (receipt = YES in Test 1)

Thus, Test 1 and Test 2 form the minimal set for full decision coverage.

Other options:

C and D are redundant for the minimal set.

A includes an extra test not needed for minimal decision coverage.

Answer: B. Test 1, Test 2

Comprehensive Detailed Explanation (Approx. 200 words):

Acceptance criteria are an essential part of requirements engineering and test design. According to the ISTQB CTFL Acceptance Testing Syllabus, acceptance criteria are defined as a set of statements that specify what must be true for a system, feature, or user story to be considered acceptable to stakeholders. These criteria are used as the basis for developing acceptance test cases and help bridge the communication between stakeholders, business analysts, developers, and testers.

They are not exclusive to Agile frameworks (contrary to option A); while common in Agile (e.g., as part of a user story), they are equally valuable in traditional lifecycles. Option B is incorrect because testers are encouraged to collaborate in defining acceptance criteria early to ensure testability and clarity. Option C incorrectly states that acceptance criteria replace acceptance tests in ATDD (Acceptance Test-Driven Development). In fact, acceptance criteria are transformed into acceptance tests during ATDD.

Exact Reference – ISTQB CTFL Acceptance Testing Syllabus (Section 2.1):

“Acceptance criteria describe the conditions under which a requirement, user story, or business process is considered successfully implemented. They provide the foundation for acceptance testing and serve as input to test case development.”

Therefore, option D is the most accurate.

Poorly defined requirements are a leading cause of defects and project failure. According to the ISTQB CTFL Acceptance Testing Syllabus and IQBBA FL Syllabus, the quality of requirements plays a critical role in successful solution development and acceptance testing. Requirements must be clear, unambiguous, complete, and testable. When they are vague or ambiguous, stakeholders may interpret them differently, which can lead to incorrect implementations, inadequate testing, and ultimately rework or rejection during acceptance.

Option A is explicitly supported by the ISTQB Foundation Syllabus and IQBBA principles. In contrast:

Option B is incorrect because Agile lifecycles still place great emphasis on requirement engineering, even though requirements evolve iteratively.

Option C misrepresents INVEST: it is a guideline for writing good user stories but does not replace reviews or validation techniques.

Option D is risky and not endorsed by ISTQB. While testers may identify ambiguities, the correct approach is to clarify them with all relevant stakeholders, not make assumptions.

Exact Reference – ISTQB CTFL Acceptance Testing Syllabus (Section 1.3.1):

“Ambiguous, incomplete, or inconsistent requirements increase the risk of misunderstanding between stakeholders, leading to incorrect implementation and ineffective tests.”

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

UX task analysis focuses on understanding how users perform their tasks in real-world contexts. It captures not only the sequence of actions but also the surrounding environment — including physical conditions (light, noise), devices used, interruptions, and constraints. These external or environmental conditions become vital inputs to UX design decisions, helping teams adapt interfaces and workflows to user realities.

Option C is correct because it emphasizes this key aspect of UX task analysis: capturing external conditions that influence usability and system interaction.

Other options:

A focuses on user profiling, not task analysis.

B refers to business process modeling, which is more strategic and less user-context specific.

D refers to benchmarking or inspiration analysis — useful for design ideation but not task analysis.

Answer: C. External conditions are considered as input for subsequent design steps.

Clear, complete, and testable requirements or user stories are critical for effective acceptance testing. Ambiguities or vague statements lead to differing interpretations by stakeholders, developers, and testers. This often results in software that doesn’t meet user expectations or in tests that fail to verify business needs correctly.

Option B is correct because it highlights the importance of precise requirements in both implementation and testing phases. Ambiguities can result in incorrect behavior, untestable features, or test cases that don’t align with business goals.

Other options:

A is risky — while testers may explore assumptions during exploratory testing, relying on assumptions rather than clarification increases risk.

C is incorrect — the INVEST mnemonic helps write better user stories, but it doesn’t replace review or validation processes.

D is false — Agile still values requirements engineering; it’s more collaborative and incremental, with the product owner playing a key role, not diminishing its importance.

Answer: B. Vague or ambiguous requirements may lead to misunderstandings both during implementation and testing
