Class DriverService

java.lang.Object

org.openqa.selenium.remote.service.DriverService

public class DriverService
extends Object

Manages the life and death of a native executable driver server. It is expected that the driver server implements the WebDriver Wire Protocol.

In addition to this, it is supposed that the driver server implements /shutdown hook that is used to stop the server.
