A selenium script is a software program that runs automated tests on websites. These scripts are written in Java and can be used with Selenium IDE. They can be used to automate repetitive tasks, such as navigating through a website or filling out web forms, and they can also be used to automate more complex tasks, like analyzing data or running regression tests.
Selenium scripts are beneficial because they are easier to write than other types of scripts and run much faster than other automation tools. They also make it easier for developers to write the code for their automation tools because the Selenium API is well documented.
