WebdriverIO

vasu34k

WebdriverIO is a mobile and browser test automation framework that has recently become quite popular in the software testing industry. 

This free and open-source framework is written in JavaScript and runs on Node.js. Packaged into npm, Webdriver is easy to install and use. This framework enables you to test web applications as well as native mobile apps.

Webdriver is popular because it is backed by Selenium which means you can run test scripts on all browsers. While it brings all the advantages of Selenium, it eliminates the pain of writing Java-based scripts.

 It allows you to easily integrate it with multiple testing frameworks such as Appium to bring the best out of both worlds.

The Key Features of WebDriverIO:

  • Run automation tests both for web applications as well as native mobile apps
  • Simple and Easy Syntax
  • Integrating tests to third-party tools such as Appium.
  • ‘Wdio setup wizard’ to make the setup simple and easy.
  • Integrated test runner

WebdriverIO Architecture

This is built over NodeJS, which is an implementation of the JSON Wire Protocol. Packaged into npm, it conducts communication using NodeJS, which is open-source and widely used for application development. It uses RESTful architecture to conduct automation testing.

The user writes the test script in JavaScript using the WebdriverIO library, where the Service request is sent via NodeJS as an HTTP command. It uses JSON Wire protocol, and the services module forwards the request to the browser.

After receiving the command, the browser performs the user actions, which tests the validity of the application functions.
