Selenium is an open source tool which is used for automating the tests carried out on web browsers (Web applications are tested using any web browser). Wait, before you get carried away, let me re-iterate that, only testing of web applications is possible with Selenium. We can neither test any desktop (software) application nor test any mobile application using Selenium.
Manual testing means the (web) application is tested manually by QA testers. Tests need to be performed manually in every environment, using a different data set and the success/ failure rate of every transaction should be recorded.
