  Answer: I have experience working with popular automated testing tools such as Selenium, Katalon Studio, and Appium. I am also comfortable using programming languages like Java and Python for test automation.
• 12. How do you prioritize testing based on risk and criticality?
  Answer: Risk-based testing is an integral part of my testing approach. I analyze and assess the potential risks involved in different features of the software and prioritize testing accordingly. Critical features are thoroughly tested to ensure minimal impact on the overall functionality of the software.
• 13. How do you handle regression testing?
  Answer: I believe in automating the regression testing process, as it can save time and effort. I also make sure to update and maintain test cases regularly to accommodate any changes to the software. In case of high-risk changes, I conduct manual regression testing to ensure complete test coverage.
• 14. Can you explain boundary value analysis and equivalence partitioning?
  Answer: Boundary value analysis is a test design technique where the system's boundaries are tested to find any defects or errors. In equivalence partitioning, the input data is divided into classes that are treated equally by the system, and only one test case from each class is executed.
• 15. How do you ensure data integrity in your testing?
  Answer: To ensure data integrity, I use techniques such as boundary testing, data validation, and data masking. I also perform cross-checks with the data source to ensure accuracy and consistency.
