Testing is the process of validating computer programs, product features and functionalities to ensure it meets the specified requirements and generates the wanted results, while identifying bugs in the embedded product. Testing is deemed as indispensable in the Product Development Lifecycle (PDLC).
Testers with manual testing skills alone won't cut it in today's job market. Yes, exploratory testing is important, and testers have certain skills that many developers do not, but the fact remains is that automation testing continues to rise. Demand for test automation has continued to grow, and now we frequently hear that some teams are completely eliminating manual testers and hiring only test professionals with test automation skills.
