Automation testing isn’t a replacement for manual testing. No matter how good automated tests are, you cannot automate everything. Manual tests play an important role in software development and come in handy whenever you have a case where you cannot use automation. Automated and manual testing each have their own strengths and weaknesses. Manual testing helps us understand the entire problem and more flexibly explore other angles of tests. On the other hand, automated testing helps save time in the long run by accomplishing a large number of surface-level tests in a short time.
