What is Selenium?
Selenium automates browsers. That’s it! What you do with that power is entirely up to you. Primarily, it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should!) also be automated as well. Selenium is a tool in the Browser Testing category of a tech Stack.
Selenium is an open source tool with 17.8K GitHub stars and 5.7K GitHub forks. Here’s a link to Selenium’s open source repository on GitHub.
