## What is WebdriverIO?

<div style="overflow: hidden">
    <article class="col2">
        WebdriverIO lets you control a browser or a mobile application with just a few lines of code. Your test code will look simple, concise and easy to read. The integrated test runner let you write asynchronous commands in a synchronous way so that you don't need to care about how to handle a Promise to avoid racing conditions. Additionally it takes away all the cumbersome setup work and manages the Selenium session for you.<br>
        <br>
        Working with elements on a page has never been easier due to its synchronous nature. When fetching or looping over elements you can use just native JavaScript functions. With the `$` and `$$` functions WebdriverIO provides useful shortcuts which can also be chained in order to move deeper in the DOM tree without using complex xPath selectors.<br>
        <br>
        The test runner also comes with a variety of hooks that allow you to interrupt the test process in order to e.g. take screenshots if an error occurs or modify the test procedure according to a previous test result. This is used by WebdriverIOs [services](/guide/services/appium.html) to integrate your tests with 3rd party tools like [Appium](http://appium.io/).

        <p>
            WebdriverIO was designed to be as flexible and framework agnostic as possible. It can be applied in any context and serves not only the purpose of testing.<br>
            <br>
            You can use it as scraper tool to dynamically fetch website data in an automated way or integrate it in your own automation library. Popular examples of that are [Spectron](http://electron.atom.io/spectron/), [Chimp](https://chimp.readme.io/) or [CodeceptJS](http://codecept.io/).

## Easy Test Setup

The `wdio` command line interface comes with a nice configuration utility that helps you to
create your config file in less than a minute. It also gives an overview of all available
3rd party packages like framework adaptions, reporter and services and installs them for you.

        <h2>How does it work?</h2>
        <p>
            WebdriverIO is an open source testing utility for nodejs. It makes it possible to write super easy selenium tests with Javascript in your favorite BDD or TDD test framework.
        </p>
        <p>
            It basically sends requests to a Selenium server via the <a href="https://www.w3.org/TR/webdriver/">WebDriver Protocol</a> and handles its response. These requests are wrapped in useful commands and can be used to test several aspects of your site in an automated way.

        <h2>Run your tests in the cloud</h2>
        <p>
            Services like Sauce Labs or BrowserStack provide selenium testing on remote hosts. They allow you to run tests on a wide collection of platforms, devices and browser combinations without any extra configuration to your environment.
