Question - What is Selenium IDE?
Answer -
Selenium integrated development environment (IDE) is an all-in-one Selenium script development environment. It may be used to debug tests, alter and record and is also available as a Firefox extension. Selenium IDE comes with the whole Selenium Core that allows us to rapidly and easily replay and record tests in the exact environment where they will be conducted.
Selenium IDE is the best environment for building Selenium tests, regardless of the style of testing we prefer, thanks to the ability to move instructions around rapidly and the autocomplete support.
