1. Which V-model level corresponds to unit testing? → Component design (detailed design)
2. What is the most significant criterion to consider while choosing a testing technique? → the objective of the test
3. Error guessing as a test technique relies primarily on: → Tester experience and intuition
4. Which testing technique requires a tester to trace all possible paths through code? → Control flow testing
5. What is the purpose of a defect triage meeting? → Review, prioritize, and assign open defects for resolution
6. What is the first step when a tester discovers a defect? → Log it in the defect tracking system with reproducible steps
7. All of the following can be found during inspections, with the exception of → How much of the code has been covered
8. Which testing technique involves testing without knowledge of the internal code structure? → Black-box testing
9. Functional testing can take the form of which of the following? → Boundary value analysis
10. Which type of testing tool is Selenium primarily used for? → Web UI automated functional testing
11. What is the benefit of standardized digital reporting in Software Testing practice? → It ensures consistency, enables comparison, and facilitates regulatory compliance
12. Which approach best demonstrates professional competency in Software Testing practice? → Integrating continuing education, practical experience, and evidence-based decision making
13. To detect a memory leak, which of the following tools would you use? → Dynamic analysis
14. Why is documentation important in Software Testing risk management? → It creates an audit trail, supports decision-making, and demonstrates due diligence
15. What is the purpose of regular risk reviews in Software Testing practice? → To identify new risks, evaluate control effectiveness, and update mitigation strategies
16. Which term describes a defect introduced while fixing another defect? → Regression defect
17. What is a test harness in software testing? → A collection of software and data that enables automated test execution
18. A defect marked as 'Deferred' means: → The defect will not be fixed in the current release but may be addressed later
19. How does continuous improvement apply to Software Testing quality management? → It involves ongoing incremental enhancements to processes based on data and feedback
20. How do continuing education requirements benefit Software Testing certified professionals? → They ensure professionals stay current with evolving industry practices and knowledge
21. Which phase includes the reporting of discrepancies as incidents → Test Analysis and Design
22. How do Software Testing professionals build trust with clients or stakeholders? → Through consistent competence, transparency, reliability, and ethical behavior
23. Why is it important to calibrate 'think time' accurately in a load test script? → To ensure simulated delays between actions reflect actual user behavior patterns
24. In a CI/CD pipeline, where should automated unit tests typically run? → At every code commit as the first quality gate
25. What does the 95th percentile response time tell you during performance test analysis? → The response time below which 95% of all requests were completed
26. Keyword-driven testing stores test logic as: → Human-readable action keywords in tables
27. What does 'defect leakage' refer to? → Defects that escape testing and reach production
28. Which of the following is NOT typically included in a test plan? → Incident reports
29. How should an Software Testing professional handle a situation outside their scope of competency? → Recognize limitations and refer to or consult with appropriate specialists
30. The term "alpha testing" refers to → pre-release testing by end user representatives at the developer's site.
