1. What is Software Testing?
Software Testing is the process of verifying and validating an application to ensure it meets business requirements and works without defects. The primary objective is to identify bugs before the software reaches end users.
2. What is the difference between Verification and Validation?
- Verification: Checks whether the product is being built correctly without executing the application.
- Validation: Checks whether the correct product has been built by executing the application.
3. What is a Bug or Defect?
A bug is an error or flaw in software that causes the application to behave differently from the expected result. Testers identify, report, and track these defects until they are resolved.
4. What is a Test Case?
A Test Case is a document containing test steps, test data, expected results, and actual results used to verify a specific functionality of an application.
5. What is the difference between Severity and Priority?
- Severity indicates how serious a defect is from a technical perspective.
- Priority indicates how urgently the defect should be fixed from a business perspective.
6. What is Regression Testing?
Regression Testing ensures that newly added features or bug fixes have not affected the existing functionalities of the application.
7. What is Smoke Testing?
Smoke Testing is performed to verify that the application’s critical functionalities are working correctly before detailed testing begins.
8. What is Sanity Testing?
Sanity Testing is performed after minor changes or bug fixes to verify that the specific functionality works correctly.
9. What is SDLC?
SDLC (Software Development Life Cycle) is the complete process of software development, including Requirement Analysis, Design, Development, Testing, Deployment, and Maintenance.
10. What is STLC?
STLC (Software Testing Life Cycle) includes Requirement Analysis, Test Planning, Test Case Development, Environment Setup, Test Execution, Defect Reporting, and Test Closure.
11. What is Black Box Testing?
Black Box Testing focuses on testing the application’s functionality without knowing its internal code or implementation.
12. What is White Box Testing?
White Box Testing involves testing the application’s internal code, logic, and structure. It is usually performed by developers.
13. What is User Acceptance Testing (UAT)?
User Acceptance Testing is the final testing phase where end users verify that the application meets business requirements before release.
14. What is Agile Testing?
Agile Testing follows Agile development principles, where testing happens continuously throughout the software development process instead of only at the end.
15. What is a Defect Life Cycle?
A defect typically moves through the following stages:
- New
- Assigned
- Open
- Fixed
- Retest
- Closed
- Reopened (if necessary)
Understanding this cycle is important for every Software Tester.
16. What is Exploratory Testing?
Exploratory Testing is an approach where testers simultaneously learn, design, and execute test cases without relying entirely on predefined scripts.
17. What are Functional and Non-Functional Testing?
Functional Testing verifies whether application features work according to business requirements.
Non-Functional Testing evaluates aspects such as performance, security, usability, scalability, and reliability.
18. What is Automation Testing?
Automation Testing uses tools such as Selenium and Playwright to execute test cases automatically. It helps improve efficiency, accuracy, and regression testing speed.
19. What makes a good Software Tester?
A good Software Tester should possess:
- Strong analytical thinking

- Effective communication skills
- Basic SQL knowledge
- Understanding of SDLC and STLC
