Selenium Tutorial
Selenium is one of the most widely used open-source Web UI automation testing tools. It supports the automation of websites across different browsers, platforms, and programming languages.
Our Selenium tutorial is designed specifically for beginners with little to no prior knowledge of Selenium or automation testing.
We will start with the basics of Selenium. After that, we will move to more advanced stuff like multi-browser testing, running tests in parallel, automation frameworks, etc.
