What is WebDriver manager?
Automation with the WebElements in the DOM (or web page) is done by using WebDriver Manager. It is beneficial since it helps in automating the entire browser setup in the Selenium codebase.
The major advantage offered by WebDriver is that there is no dependency on downloading the latest version of WebDriver. This is done by default by WebDriver Manager.
If you are using Java Maven or Gradle, all you need to do is add the location of WebDriver Manager in pom.xml
