iSQI CTAL-ATT Practice Test Questions Answers

Purpose of Service Virtualization:Service virtualization allows simulation of external services during testing, enabling cost-effective and efficient testing without relying on the live service.

Cost Reduction:The bank charges per transaction, and using the actual service during continuous testing could incur significant fees. Virtualized services eliminate these fees, reducing costs.

Analysis of Options:

A: While a virtualized service may improve speed, the primary benefit here is cost savings.

B: Correct, as eliminating transaction fees directly addresses the problem.

C: Virtualization doesn’t inherently improve security for automation code.

D: Virtualized services don’t necessarily reduce data management needs.

Conclusion:Option B is correct as it highlights the key advantage of cost savings.

Safety-Critical Testing Requirements:Safety-critical projects demand high levels of traceability to ensure every test is linked to its corresponding requirement and outcome.

Automation Goals:While automation can support regression testing and other approaches, the primary focus in safety-critical projects is to meet compliance standards, which include traceability.

Conclusion:Option B is correct because it highlights traceability, a critical aspect of process-compliant safety-critical testing.

What is Static Code Analysis?

Static code analysis examines code without executing it, identifying issues such as inefficiencies, complexities, and vulnerabilities.

How It Reduces Technical Debt:

By pinpointing areas of inefficient or overly complex code, developers can address these issues early, reducing the accumulation of technical debt over time.

Security vulnerabilities identified through static analysis prevent future costly rework or fixes.

Analyzing the Options:

A: Correctly identifies the benefits of identifying inefficiencies, complexities, and insecure code.

B: Static analysis happens after code is written, not during the writing process.

C: Static analysis complements but does not replace code reviews.

D: Static analysis does not replace unit tests, as they serve different purposes.

References:Aligned with ISTQB Advanced Agile Technical Tester syllabus on technical debt management and the role of static code analysis.

Data-Driven Testing:Data-driven testing focuses on varying inputs and verifying expected outputs. For this story, the key input is the quantity of items purchased, and the output is whether free shipping applies.

Relevant Columns:

Item ID: Identifies the product.

Quantity Purchased: Determines whether the free shipping threshold is met.

Free Shipping (y/n): Validates if the message is correctly displayed.

Conclusion:Option B is correct as it includes the minimum required data to test the user story effectively.

Preferred Approach for Acceptance Criteria:

Collaboratively eliciting examples from the product owner ensures that the acceptance criteria reflect real-world usage and expectations.

Combining these examples with testing techniques ensures coverage of edge cases and system behavior.

Analyzing Options:

A: Proposes specific criteria but does not involve the product owner in the process.

B: Boundary value analysis is useful but does not address broader acceptance criteria.

D: Lists numerous acceptance criteria without first understanding the product owner’s expectations.

References:Aligned with ISTQB Agile Technical Tester syllabus emphasizing collaboration with stakeholders to define robust acceptance criteria.
