Section 1: Basic AQM Software Testing Lab Interview Questions

1. What is software testing?

Software testing is the process of verifying and validating a software application to ensure that:

  • It meets business requirements

Testing is important because:

  • Clients expect high-quality deliverables
  • Early defect detection reduces cost
  • It improves customer satisfaction
  • It prevents production failures

3. What is the difference between verification and validation?

VerificationValidation
Are we building the product right?Are we building the right product?
Static activityDynamic activity
Reviews & inspectionsTest execution

4. What is a bug or defect?

A defect is a situation where:

Actual Result ≠ Expected Result

5. Difference between error, defect, and failure

TermMeaning
ErrorMistake by developer
DefectBug found during testing

8. What is manual testing?

Manual testing is testing software without using automation tools, where testers:

  • Execute test cases manually

  • Log defects

9. What is automation testing?

Automation testing uses tools/scripts to:

  • Execute repetitive test cases
  • Reduce execution time

No. Manual testing is essential for:

  • Exploratory testing
  • Usability testing
  • Business validation

Automation supports manual testing.

Section 2: Test Case Interview Questions (Very Important at AQM)

A test case is a set of steps, test data, and expected results used to verify a specific requirement.

12. What are the components of a test case?

  • Test Case ID
  • Test Scenario / Title
  • Preconditions
  • Test Steps
  • Test Data
  • Expected Result
  • Actual Result
  • Status

13. What is a test scenario?

A test scenario is a high-level functionality to be tested.

Example: User registration.

14. Difference between test scenario and test case

Test ScenarioTest Case
High-levelDetailed
What to testHow to test

15. What is positive testing?

Testing with valid inputs to confirm the system works as expected.

16. What is negative testing?

Testing with invalid inputs to ensure proper error handling.

17. What is boundary value analysis?

Testing values at:

  • Minimum boundary
  • Maximum boundary
  • Just below and above limits

18. What is equivalence partitioning?

Dividing input data into:

  • Valid partitions
  • Invalid partitions

19. What makes a good test case in AQM projects?

  • Clear and easy to understand
  • Business-oriented
  • Covers edge cases
  • Traceable to requirements

20. What is regression testing?

Regression testing ensures existing functionality works correctly after changes.
