Manual testing is still important for certain types of testing like unit testing, system testing, regression testing, and user acceptance testing. It is performed by professional testers, subject matter experts, business analysts, and end-users. While manual testing is slow, automation can provide faster feedback, consistency, empower testers, and increase confidence through documentation. However, test automation requires extensive upfront time and maintenance. The best approach is to use manual testing to develop test assets like requirements, risk assessments, and defect records that can then be used to develop automated test cases. This hybrid approach allows organizations to take advantage of both manual and automated testing.
