1. What is software testing?

Software testing is the process of evaluating a software application or system to determine if it meets the specified requirements and quality standards.

2. What is the difference between verification and validation?

Verification is the process of evaluating a product or system to determine whether it meets the specified requirements, while validation is the process of evaluating a product or system to determine whether it meets the needs of the customer and intended users.

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

Functional testing is the process of testing the functionality of a software application, while non-functional testing is the process of testing the non-functional aspects of a software application, such as performance, security, and usability.

4. What is the difference between black-box testing and white-box testing?

Black-box testing is the process of testing a software application without knowledge of its internal workings, while white-box testing is the process of testing a software application with knowledge of its internal workings.

5. What is a test plan?

A test plan is a document that outlines the objectives, scope, approach, resources, and schedule of a software testing project.

6. What is a test case?

A test case is a document that describes the input, actions, and expected results of a particular test scenario.

7. What is a test scenario?

A test scenario is a description of a specific condition or situation that a software application or system must be able to handle.

8. What is a defect?

A defect is any deviation from the expected behavior of a software application or system.

9. What is a bug?

A bug is a specific type of defect that causes the software application or system to behave in unexpected ways.

10. What is regression testing?

Regression testing is the process of retesting a software application or system after changes have been made to ensure that previously working functionality has not been negatively affected.

11. What is smoke testing?

Smoke testing is the process of testing a software application or system to ensure that it is stable enough to conduct further testing.

12. What is integration testing?

Integration testing is the process of testing the interfaces between different modules or components of a software application or system.

13. What is system testing?

System testing is the process of testing a software application or system as a whole to ensure that it meets the specified requirements and quality standards.

14. What is acceptance testing?

Acceptance testing is the process of testing a software application or system to ensure that it meets the needs of the customer and intended users.

15. What is usability testing?

Usability testing is the process of testing a software application or system to ensure that it is easy to use and understand for its intended users.

16. What is performance testing?

Performance testing is the process of testing a software application or system to ensure that it meets the specified performance requirements.

17. What is load testing?

Load testing is the process of testing a software application or system to determine how it performs under various levels of load.

18. What is stress testing?

Stress testing is the process of testing a software application or system to determine how it performs under extreme conditions.

19. What is security testing?

Security testing is the process of testing a software application or system to ensure that it is secure from potential threats and vulnerabilities.

20. What is exploratory testing?

Exploratory testing is the process of testing a software application or system by exploring it in an unscripted and unplanned manner to discover defects and issues.

21. What is the difference between manual testing and automated testing?

Manual testing is the process of testing a software application or system by manually executing test cases, while automated testing is the process of testing a software application or system using automated tools and scripts.
