Answer: In my previous role, I utilized automation tools such as Selenium to improve testing efficiency and effectiveness. I created automated test scripts to run regression tests and reduce manual testing efforts, which resulted in significant time savings.
- What testing methodologies have you worked with?
Answer: In my previous roles, I have worked with Agile and Waterfall methodologies. I have used Agile to ensure that products were delivered on time and meet quality standards through continuous testing and feedback, while Waterfall was used for larger-scale projects that required more structure and planning.
- How do you ensure that your test cases cover all possible scenarios?
Answer: I ensure that my test cases cover all possible scenarios by using a combination of techniques, such as risk-based testing, boundary value analysis, and equivalence partitioning. I prioritize scenarios based on importance and risk, and ensure that each scenario is covered by at least one test case.
- How do you handle test case failures?
Answer: I analyze test case failures to identify the root cause of the failure and work with the development team to resolve the issue. I also update test cases to ensure that similar failures do not occur in the future.
- How do you ensure that your testing is thorough?
