14. How do you determine if a defect is valid or not?
Answer: To determine the validity of a defect, I analyze the defect by verifying if it aligns with the software’s expected behavior as defined in the requirements. I also consider the severity, impact on functionality, and reproducibility of the defect before classifying it as valid or invalid.

15. What is the role of a Quality Assurance Tester in the software development life cycle?
Answer: The role of a Quality Assurance Tester involves active participation in various phases of the software development life cycle, including requirements analysis, test planning, test case design, test execution, defect reporting, and test closure. They act as the gatekeepers for ensuring product quality.

16. How do you approach continuous integration and continuous delivery (CI/CD) in terms of quality assurance?
Answer: In CI/CD environments, quality assurance plays a vital role in ensuring that each new version or change made to the software goes through automated and manual tests. I work closely with the development team to establish effective test automation frameworks, identify suitable areas for automated tests, and ensure timely execution of tests at each stage of CI/CD.

17. How do you stay updated with the latest trends and practices in Quality Assurance?
Answer: I have a strong commitment to continuous learning and development. I actively participate in industry forums, attend webinars, read relevant blogs and articles, and join professional communities to stay updated with the latest trends and practices in Quality Assurance.

18. How do you handle a situation where a critical defect is found just before the software release?
Answer: If a critical defect is found just before the software release, I notify the project stakeholders immediately. I work with the development team to assess the impact and potential solutions. If necessary, I recommend postponing the release until the critical defect is fixed to maintain the quality of the software.

19. How do you ensure effective collaboration within a distributed team?
Answer: Communication and collaboration are key in a distributed team setup. I ensure the use of communication tools like video conferencing, instant messaging, and project management tools to stay connected. Regularly scheduled team meetings, clear documentation, and well-defined processes help maintain effective collaboration within distributed teams.

20. Can you explain the difference between smoke testing and sanity testing?
Answer: Smoke testing is a minimal set of tests performed on each build to verify the basic functionality and stability of the software, whereas sanity testing is a more focused set of tests targeting specific areas or functionalities of the software to ascertain its sanity for further testing.

1. Why is quality assurance important in software development?
Quality assurance ensures that the software being developed meets the necessary requirements and is free from defects. It helps in delivering a high-quality product and enhances customer satisfaction.
