What is your percentage ratio of manual to automated testing?

The percentage ratio of manual to automated testing depends on the project and its requirements. Usually, for a middle level, I try to maintain a balance of about 30-40% manual testing and 60-70% automated testing. Manual testing is important for checking UX, exploratory testing, and cases where automation is not feasible. Automation, on the other hand, allows for quick and reliable regression testing and repetitive scenarios. Ideally, automation covers the main critical paths, and manual testing complements it where flexibility and human insight are needed.
