| Test Execution | Execute test cases & log defects |
| Test Closure | Metrics, reports, sign-off |
4. Difference between SDLC and STLC?
| SDLC | STLC |
| Development lifecycle | Testing lifecycle |
| Focus on building product | Focus on validating product |
| Ends at maintenance | Ends at test closure |
5. What is requirement analysis in testing?
Answer:
Requirement analysis involves reviewing requirements to understand functionality, identify ambiguities, determine test scenarios, and ensure testability.
6. What is RTM?
Answer:
RTM (Requirement Traceability Matrix) maps requirements to test cases to ensure complete coverage and avoid missed requirements.
7. What types of testing have you performed?
Answer:
- Functional testing
- Regression testing
- Smoke & sanity testing
- Integration testing
- System testing
- UAT support
8. Difference between smoke and sanity testing?
| Smoke | Sanity |
| Broad testing | Focused testing |
| Build verification | Bug fix verification |
| Done on new build | Done on stable build |
9. What is regression testing?
Answer:
Regression testing ensures that new changes or bug fixes do not break existing functionality.
10. How do you prioritize test cases?
Answer:
- Business-critical flows
- High-risk areas
