2. Core Software Testing Interview Questions & Structured Answers
Q1. What is software testing?
Answer:
Software testing is the process of verifying and validating a software application to ensure it meets business requirements, works correctly, and provides a good user experience.
At 3 years, testing also means anticipating user behavior, identifying edge cases, and reducing production defects.
Q2. What types of testing have you performed?
Answer:
- Functional testing
- Smoke testing
- Sanity testing
- Regression testing
- Integration testing
- System testing
- Cross-browser testing
- UAT support
- Basic API testing
- Database validation
Q3. Explain SDLC and your role as a tester.
Answer:
SDLC (Software Development Life Cycle) phases:
- Requirement Analysis
- Design
- Development
- Testing
- Deployment
- Maintenance
My role includes:
- Reviewing requirements for clarity and testability
- Identifying test scenarios and risks
- Designing and executing test cases
- Logging and tracking defects
- Performing smoke testing after deployments
- Supporting UAT and production issues
Q4. Explain STLC with real-time relevance.
Answer:
STLC (Software Testing Life Cycle) phases:
- Requirement Analysis
- Test Planning
- Test Case Design
- Test Environment Setup
- Test Execution
- Test Closure
In Agile projects, STLC activities are iterative and continuous, aligned with sprint cycles.
Q5. Difference between verification and validation?
Answer:
- Verification: Reviewing documents like requirements and designs
- Validation: Executing test cases on the application
Verification ensures the product is built correctly; validation ensures the correct product is built.
Q6. What is functional testing?
Answer:
Functional testing verifies application behavior against business requirements by validating inputs, outputs, and business rules.
Q7. What is regression testing and when do you perform it?
Answer:
Regression testing ensures existing functionality is not broken after:
- Bug fixes
- New feature additions
- Configuration changes
It is typically performed before every release.
Q8. Difference between smoke testing and sanity testing?
Answer:
| Smoke Testing | Sanity Testing |
| Broad testing | Narrow testing |
| Build stability check | Change verification |
| New build | After bug fixes |
Q9. What test design techniques do you use?
Answer:
- Boundary Value Analysis – testing edge values
- Equivalence Partitioning – grouping similar inputs
- Error Guessing – based on experience
Q10. How do you prioritize test cases?
Answer:
Test cases are prioritized based on:
- Business criticality
- User impact
- Risk and complexity
- Frequency of usage
3. Agile & Scrum Interview Questions (3 Years Level)
Q11. What is Agile testing?
Answer:
Agile testing is continuous testing where QA works closely with developers and product owners to provide quick feedback throughout the sprint.
Q12. Which Agile ceremonies have you attended?
Answer:
- Sprint planning
- Daily stand-ups
- Sprint review
- Retrospective
Q13. What is your role in sprint planning?
Answer:
- Understand user stories and acceptance criteria
- Estimate testing effort
- Identify dependencies and risks
Q14. How do you handle frequently changing requirements?
Answer:
I analyze the impact, update test cases, communicate changes early, and ensure impacted areas are retested.
4. Scenario-Based Interview Questions + RCA
Scenario 1: User Can Access Application After Logout
Issue: User clicks browser back button after logout
RCA:
- Session not invalidated on server side
- Browser cache enabled
Fix:
- Invalidate session on logout
- Disable caching for secured pages
Scenario 2: Duplicate Records Created
Issue: User clicks submit button multiple times
RCA:
- No double-submit prevention
- Missing backend validation
Fix:
- Disable submit button after click
- Add backend duplicate check
Scenario 3: Application Accepts Invalid Characters
RCA:
- Missing input validation
Fix:
- Validate inputs at UI and backend
Scenario 4: API Returns 200 for Invalid Input
RCA:
- Missing backend validation
Fix:
- Return proper HTTP status codes
Scenario 5: Production Defect Missed by QA
RCA:
- Test data mismatch
- Incomplete regression scope
Fix:
- Improve test data coverage
- Strengthen regression checklist
5. Test Case Examples (UI, API, DB, Performance)
UI Test Case Example
| Field | Value |
| Test Case ID | TC_LOGIN_01 |
| Scenario | Invalid login |
| Steps | Enter wrong credentials |
| Expected Result | Error message |
| Priority | High |
API Test Case Example
- Send invalid payload
- Validate status code = 400
- Validate error message
Database Validation Example
SELECT status
FROM orders
WHERE order_id = 4001;
Performance Sanity Checks
- Page load time < 3 seconds
- No timeout under normal load
6. Bug Reports & Defect Management
What makes a good bug report?
- Clear summary
- Steps to reproduce
- Expected vs actual result
