Difference Between Cypress vs WebDriverIO. Which one to Choose?



What is Cypress?

Cypress framework is the popular end-to-end automation framework. It is built on NodeJS and provides the ability to write the automation scripts using JavaScript and Typescript programming languages. Cypress quickly gained users because of its unique features such as debuggability, stable test runs, time travel, automatic waiting, and screen capture.

But like any other automation framework, Cypress also has some limitations like iFrame Support, multiple window support, cross-origin restriction, etc. Cypress is an open-source framework that comes with an MIT license. One can just install Cypress npm node packages and start testing.

Cypress Features:
  1. Beginner friendly setup

  2. Tests are easy to read and understand

  3. Not dependent on Selenium Webdriver

  4. Interactive test runner

  5. Built-in wait and retries

  6. API testing support


Limitation:
  1. Limited browser support

  2. cross-origin restrictions

  3. Multi-tab and multi-windows not supported

  4. Built-in parallelization not supported


What is WebdriverIO?

WebdriverIO framework is an end-to-end testing framework, owned by a non-profit organization called OpenJS foundation and follows W3 recommendations for architectural designs. It is a NodeJS based application that provides the ability to test applications using JavaScript/TypeScript.

WebdriverIO can be configured to use Webdriver Protocol or ChromeDevTools Protocol. Mostly WebdriverIO is used with WebdriverProtocol since it provides rich features like cross browser testing. WebdriverIO is completely open-source. Unlike Cypress, it doesn’t offer any commercial option.

WebdriverIO Features:
  1. Beginner friendly setup (customized)

  2. Tests are easy to understand for JS users

  3. User custom implementation of Webdriver
