Manual testing has evolved significantly in the age of automation. Initially, manual testing was the primary method for ensuring software quality, involving human testers to find bugs and ensure functionality. However, as software development accelerated, the limitations of manual testing—such as time consumption and susceptibility to human error—became apparent. Automation tools emerged, offering faster and more reliable testing. Despite this shift, manual testing remains essential for exploratory, usability, and ad-hoc testing, where human intuition and understanding of user experience are irreplaceable. The future likely holds a balanced approach, leveraging both manual and automated testing strategies.
