Interview Prep (Wise Edition)

 

Basic QA Concepts

1. What is Quality Assurance (QA)?

   • QA ensures that products meet specified requirements and are free of defects through systematic activities like planning, implementation, and evaluation.

2. What is the difference between QA and Quality Control (QC)?

   • QA focuses on preventing defects by improving processes, while QC involves identifying defects in the final product through testing.

3. What is the difference between verification and validation?

   • Verification checks if the product meets design specifications; validation ensures the product fulfills its intended purpose.

4. What is a test case?

   • A test case is a set of conditions and inputs used to determine if a system functions correctly.

5. What is a test plan?

   • A test plan outlines the scope, approach, resources, and schedule for testing activities.

6. What is the difference between a test case and a test scenario?

   • A test scenario is a high-level description of what to test; a test case provides detailed steps and expected results.

7. What is a bug or defect?

   • A bug is an error or flaw in the software that causes it to produce incorrect or unexpected results.

8. What is the software testing life cycle (STLC)?

   • STLC includes phases like requirement analysis, test planning, test case development, environment setup, test execution, and test closure.

9. What is the difference between functional and non-functional testing?

   • Functional testing verifies specific actions or functions of the code; non-functional testing assesses aspects like performance and usability.

10. What is regression testing?

    • Regression testing ensures that new code changes haven't adversely affected existing functionalities.

Intermediate QA Concepts

11. What is exploratory testing?

    • Exploratory testing involves simultaneous learning, test design, and execution to explore the software's behavior.

12. What is a test strategy?

    • A test strategy is a high-level document outlining the testing approach, objectives, and resources.

13. What is the difference between smoke and sanity testing?

    • Smoke testing checks basic functionalities; sanity testing verifies specific functionalities after changes.

14. What is boundary value analysis?

    • It's a testing technique focusing on values at the boundaries of input domains.

15. What is equivalence partitioning?

    • It divides input data into equivalent partitions to reduce test cases while maintaining coverage.

16. What is the difference between alpha and beta testing?

    • Alpha testing is internal; beta testing is conducted by external users before the final release.

17. What is usability testing?

    • Usability testing evaluates how user-friendly and intuitive the software is.

18. What is compatibility testing?

    • It checks if the software works across different devices, browsers, and operating systems.

19. What is localization testing?

    • It ensures the software is adapted for a specific region or language.

20. What is internationalization testing?

    • It verifies that the software can be adapted to various languages and regions without engineering changes.

Advanced QA Concepts

21. What is automation testing?

    • Automation testing uses tools to execute test cases, reducing manual effort and increasing efficiency.

22. What are some popular automation tools?

    • Selenium, QTP, TestComplete, and Appium are commonly used automation tools.

23. What is a test automation framework?

    • It's a set of guidelines and tools to create and design test cases efficiently.

24. What is continuous integration (CI)?

    • CI is a development practice where code changes are automatically tested and integrated into the main branch.

25. What is continuous testing?

    • Continuous testing involves executing automated tests as part of the software delivery pipeline to get immediate feedback.

26. What is performance testing?

    • It assesses the speed, responsiveness, and stability of a system under a workload.

27. What is load testing?

    • Load testing evaluates system behavior under expected user loads.

28. What is stress testing?

    • Stress testing determines the system's robustness by testing beyond normal operational capacity.

29. What is security testing?

    • It identifies vulnerabilities and ensures that data and resources are protected from potential breaches.

30. What is API testing?

    • API testing checks the functionality, reliability, and security of application programming interfaces.
