Selenium
Selenium is a popular tool that helps companies make sure their websites and applications work correctly by automatically testing them. Think of it like a robot that can click through websites, fill out forms, and check if everything works as expected - just like a real user would do, but much faster. This saves time for companies because they don't need people to manually check every part of their website whenever they make changes. When you see Selenium mentioned in a resume, it usually means the person knows how to create and manage these automated tests. This skill is especially valuable because it helps catch problems before customers find them.
