Expert Answer: I have experience with functional testing (unit, integration, system, acceptance), non-functional testing (performance, security, usability, compatibility), API testing, database testing, mobile testing, and accessibility testing. I understand black-box, white-box, and gray-box testing approaches, and have performed smoke, sanity, regression, and exploratory testing.
Example: "In my recent project, I performed end-to-end functional testing of a banking application, conducted API testing using Postman for 50+ endpoints, executed performance testing with JMeter handling 1000 concurrent users, and performed security testing for SQL injection and XSS vulnerabilities. This comprehensive testing approach ensured 99.9% application reliability in production."
