How to answer: Define boundary testing and describe how it checks the system's behavior at the edges of valid input ranges to identify potential issues.

Example Answer: "Boundary testing is a type of testing that examines the system's behavior at the edges of valid input ranges. It helps identify issues that may occur when input values are at their minimum or maximum allowable limits. By testing boundaries, we can uncover defects related to data handling, calculations, or other system functions."

21. How do you approach test case prioritization?

The interviewer is interested in your approach to prioritizing test cases based on factors like risk and criticality.

How to answer: Explain your methodology for prioritizing test cases, considering factors such as business impact, risk assessment, and test dependencies.

Example Answer: "I prioritize test cases based on business impact, ensuring that critical functionality is thoroughly tested first. I also consider risk factors, focusing on areas where defects could have severe consequences. Test dependencies are taken into account, so I test prerequisites before dependent functions to maximize test coverage and efficiency."

22. How do you handle situations where requirements are not clear or constantly changing?

The interviewer wants to assess your adaptability and problem-solving skills in situations with evolving or unclear requirements.

How to answer: Describe how you communicate with stakeholders, seek clarification, and document changes. Emphasize your ability to adapt and ensure the testing process aligns with changing requirements.

Example Answer: "In situations with unclear or changing requirements, I proactively engage with stakeholders to seek clarification and gather additional information. I document all requirements and changes meticulously. I maintain flexibility in my testing approach, allowing for adjustments as requirements evolve. This ensures that the testing process aligns with the project's changing needs while maintaining testing quality."

23. What is the difference between smoke testing and sanity testing?

The interviewer is interested in your understanding of smoke testing and sanity testing and how they differ.

How to answer: Explain that smoke testing is a subset of regression testing that checks if the software build is stable, while sanity testing is a subset of acceptance testing that verifies specific functionality.

Example Answer: "Smoke testing is a quick and broad test of the entire software build to determine its stability. It verifies if the critical functions are working before proceeding with further testing. Sanity testing, on the other hand, is a narrower, focused test that checks specific functionality or components to ensure they are working correctly after changes or new features have been added."

24. Can you explain the importance of documentation in software testing?

The interviewer is assessing your understanding of the role of documentation in the testing process.

How to answer: Describe the importance of documentation in maintaining test cases, tracking test results, and ensuring transparency for team members and stakeholders.

Example Answer: "Documentation is crucial in software testing as it helps in maintaining test cases, tracking test results, and ensuring transparency.
