Once, there was a time when testers had to manually test everything in Joomla, clicking through all the views and features each and every time a change was made. It was exhausting, cumbersome and prone to errors.
Along came Selenium! A tool to automatically control browsers, defining long click paths through all of Joomla, repeatable, reliable, not exhausting and requiring less people-power. And the testers saw all the tests that they made, and it was very good.
