One constraint in Selenium automation is that we need to download the driver binary executable for Chrome, Firefox, and Internet Explorer. After downloading the executable files for Java, the absolute path of this executable file has to be set to JVM properties using System.setProperty. This was an overhead which has been removed with the introduction of a library called WebDriverManager.
Remember to use JDK 1.8 with this library. It won't work with JDK 1.7.
With this library, there is no need to download the individual binaries for the different browsers. Earlier, we had to manage the versions of the binaries manually. With this library, this gets handled automatically.
