Free iSQI CTAL-ATT Practice Exam with Questions & Answers | Set: 2

Refactoring Test Cases:

Refactoring improves test case readability and maintainability, ensuring they can be understood and updated as the system evolves.

In Agile, where code changes frequently, clear test cases are essential for quick adaptation and collaboration among testers.

Analyzing the Options:

A: Developers may not necessarily use these test cases for performance testing.

C: Users performing UAT focus on business scenarios, not technical test cases.

D: Test cases are for internal team use; product owners typically review acceptance criteria or feature behavior.

B: Correctly identifies the importance of refactoring for maintainability and collaboration as the system changes.

References:Aligned with ISTQB Advanced Agile Technical Tester syllabus, which highlights the need for test case clarity to support agile practices and team collaboration.

Review of User Story:The story's focus is on notifying the customer of the delivery time, not the shipping fee or free shipping qualification.

Analyzing the Charter:

The charter mentions verifying shipping fees, which is unrelated to the functionality of the user story.

It does not address delivery time notifications, which are the main purpose of the user story.

Alignment with Agile Testing Principles:Agile testing requires charters to align closely with the story’s intent and customer goals.

Conclusion:The main flaw is that the charter does not test the core functionality of the story, making Option B correct.

Goals of Test Case Refactoring:

Refactoring aims to improve the quality of test cases while ensuring they continue to validate the product’s functionality, especially after changes.

Analyzing the Options:

A: Ensuring the test cases adequately test the product aligns with the purpose of refactoring.

B: Detecting defects is a testing goal, not a specific purpose of refactoring.

C: Refactoring focuses on improving clarity and maintainability, not on UAT usability.

D: Reducing detail is not a primary objective; retaining adequate coverage is crucial.

References:Consistent with ISTQB Agile Technical Tester syllabus focusing on maintaining test coverage and functionality after refactoring.

Understanding the Scenario:

The requirement is to collect structured feedback from a large user base.

The method should allow users to select predefined answers, making the process scalable and results analyzable.

Why Quantitative Questionnaires?

Quantitative questionnaires are structured tools with predefined answers, ideal for efficiently gathering measurable data from a large group.

The results can be statistically analyzed to identify trends and commonalities, aiding in defining clear acceptance criteria.

Eliminating Other Options:

B. Qualitative Questionnaires: These involve open-ended responses, which are harder to standardize and analyze, especially for large user groups.

C. Quantitative Interviews: These require individual interaction, making them less efficient for engaging large groups.

D. Qualitative Interviews: These are exploratory and subjective, not suitable for structured data collection or defining clear criteria.

References:Aligned with ISTQB Advanced Agile Technical Tester objectives, which recommend using structured elicitation methods like quantitative questionnaires for large-scale feedback.

Analyzing the TDD Process:

The provided test cases only cover two inputs: "smith" and "x," and these pass successfully.

Real-world inputs such as longer names ("Steinbrenner") or edge cases (blank inputs) are not tested, resulting in errors and crashes.

Insufficient Tests:

The developers have not accounted for all possible input scenarios, such as names exceeding 30 characters or invalid inputs.

Expanding the tests to cover such cases would align the implementation with the acceptance criteria.

Analyzing the Options:

A: The tests are running but are inadequate in scope.

B: The tests are likely passing for the covered cases but fail to address uncovered scenarios.

D: The story already includes relevant details; the issue lies with test case insufficiency.

References:Aligned with ISTQB guidance on the importance of comprehensive test coverage in TDD.

Definition of Test Automation:Test automation is not a procedure, objective, or methodology. Instead, it is a strategic approach to automate testing activities to improve efficiency and coverage.

Strategic Nature:The ISTQB syllabus defines test automation as a strategy that integrates automated tests into the development lifecycle.

Conclusion:Option C is correct as test automation aligns with the definition of a strategy.

Testing Constraints in CI:The time limitations for test execution and results review necessitate prioritization of tests based on criticality and frequency of code changes.

Efficient Allocation:

High-priority tests should run on each build to catch critical issues early.

Medium-priority tests can be run nightly to balance coverage and time constraints.

Low-priority tests are less critical and can run weekly.

Non-functional tests require the integrated stage environment and should run at a predefined time (e.g., Thursday night before sprint end).

Analysis of Options:

A: Running all tests every night is impractical due to time constraints.

B: Medium-priority tests should be run more frequently than at the end of the sprint.

C: Running all tests on every build is unrealistic given the time and resource limitations.

D: Correct, as it ensures efficient prioritization and scheduling of test sets.

Conclusion:Option D provides the most efficient and effective test execution strategy.

Understanding Refinement Needs in Acceptance Criteria:

Well-defined acceptance criteria must be clear, measurable, and testable.

Criteria that lack specificity or are too broad need refinement to ensure they can be implemented and tested effectively.

Analyzing the Options:

A: "The backend system must respond to the mobile app within 3 seconds" is clear, measurable, and testable.

C: "The mobile app must detect when the phone does not have Internet connectivity and display a warning message" is actionable and measurable.

D: "The payload delivered by the backend system must use JSON formatting" is specific and testable.

B: "The communication between the two systems must be secure" lacks details. Security requirements should specify the protocols or methods (e.g., TLS encryption) to make the acceptance criteria clear and actionable.

References:Aligned with ISTQB Agile Technical Tester principles emphasizing clear, testable acceptance criteria for Agile stories.

Automation and System Criticality:

For mission-critical systems, automation ensures consistent, repeatable testing, particularly for high-risk functionalities.

As risk increases, automation plays a key role in validating critical features and reducing the chance of human error.

For non-critical systems, the focus on automation is generally reduced, depending on cost-benefit analysis.

Analyzing the Options:

A: Correctly states that automation is prioritized for mission-critical systems as risk increases.

B: Incorrectly diminishes the importance of automation for non-critical systems without clarifying context.

C: Misrepresents automation levels as equal for critical and non-critical systems.

D: Incorrectly dismisses automation for non-critical systems, which can be valuable depending on the context.

References:ISTQB Agile Technical Tester syllabus emphasizes automation for high-risk systems while balancing cost and risk for non-critical systems.

Quantitative questionnaires are best suited for eliciting non-functional requirements from a large number of stakeholders. This is because they allow for the collection of measurable, statistical data that can be analyzed to understand the stakeholders’ needs regarding system qualities like performance, usability, and reliability. These questionnaires can be designed to include specific questions about non-functional aspects, which can then be quantitatively assessed to inform the acceptance criteria1.

References = The ISTQB Advanced Level Agile Technical Tester syllabus and study resources emphasize the importance of understanding and defining both functional and non-functional requirements in Agile environments. They outline various elicitation techniques that can be used to gather these requirements, including the use of questionnaires for collecting quantitative data23.
