WebdriverIO from webdriver.io is a JavaScript library for controlling browsers with Selenium server via the WebDriver API.
WebdriverIO is an independent implementation of the WebDriver Protocol which provides language bindings and APIs to automate browser or mobile devices. Its test runner allows you to write your tests in a synchronous way so you’re not constantly in the world of asynchronous coding. WebDriverIO integrates easily with a variety of cloud browser testing vendors (for example, Sauce Labs, BrowserStack and CrossBrowserTesting), so you can perform tests on a wide variety of OS/Device/Browser combinations, all from one test.
