# Estimated publication date: 04 June 2018

# Abstract
WebDriver is a remote control interface that enables introspection and
control of user agents. It provides a platform- and language-neutral wire
protocol as a way for out-of-process programs to remotely instruct the
behavior of web browsers.  Provided is a set of interfaces to discover and
manipulate DOM elements in web documents and to control the behavior of a
user agent. It is primarily intended to allow web authors to write tests
that automate a user agent from a separate controlling process, but may
also be used in such a way as to allow in-browser scripts to control a —
possibly separate — browser.  The standard forms part of the Web Testing
Activity that authors a larger set of tools commonly used for testing.
