What is WebdriverIO?
WebdriverIO is an open-source testing automation framework written in JavaScript and running on NodeJS, which means it makes it possible to write tests that control a browser from the comfort of your own code. It has a few different ways of doing this, including by simulating user clicks and typing text. This ability is extremely useful for testing web apps, which are often difficult to test manually. WebdriverIO can also be used for other kinds of browser automation, such as to scrape data from web pages or even to drive the browser on a mobile device.
