Karma vs WebdriverIO: What are the differences?

What is Karma? Spectacular Test Runner for JavaScript. Karma is not a testing framework, nor an assertion library. Karma just launches a HTTP server, and generates the test runner HTML file you probably already know from your favourite testing framework. So for testing purposes you can use pretty much anything you like.

What is WebdriverIO? Webdriver/Selenium 2.0 JavaScript bindings for Node.js. 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.

Karma and WebdriverIO can be categorized as "Browser Testing" tools.

Some of the features offered by Karma are:

  • Test on Real Devices
  • Remote Control
  • Testing Framework Agnostic

On the other hand, WebdriverIO provides the following key features:

  • Extendable
  • Support for the WebDriver specification as well as to Appium
  • Easy Test Setup

Karma and WebdriverIO are both open source tools. It seems that Karma with 10.7K GitHub stars and 1.61K forks on GitHub has more adoption than WebdriverIO with 5.04K GitHub stars and 1.44K GitHub forks.

Typeform, Accenture, and Sellsuki are some of the popular companies that use Karma, whereas WebdriverIO is used by SuperAgendador.com, Soluto, and Shelf. Karma has a broader approval, being mentioned in 119 company stacks & 57 developers stacks; compared to WebdriverIO, which is listed in 7 company stacks and 3 developer stacks.

Hi, I am starting out to test an application that is currently being developed - FE: React. BE: Node JS. I want the framework to be able to test all UI scenarios (from simple to complex) and also have the capability to test APIs. I also need to run tests across all OSs and Browsers (Windows, Mac, Android, iOS). I have also looked into react-testing-library and @TestProject.io. Any advice you can give as to which framework would be best and why would be so much appreciated! Thank you!!

You should also definitely look into Playwright, which is a new automation tool from Microsoft building on top of the Puppeteer experience and trying to bring this experience in the cross browser space - very exciting project. Great team. Also CodeceptJS as already Playwright support which at a ton of valuable features on top of Playwright, give it a go!

I'm also looking for the same, FE: React & BE: NodeJS. Cypress won't help as it lacks cross-browser testing, it doesn't support all the browsers. I'm still investigating it, but looks like WebdriverIO may fulfil what I'm looking for - Cross-browser testing, integration with CI/CD, running it as a docker service, good support on assertions & reporting of test results. Let me know if you found any information on any of the above mentioned points.

Hi Esther, if you really need cross OS and cross device automation Cypress wont help, with WebdriverIO you can do it … and check out CodeceptJS, which is a wrapper around several frameworks (like WebdriverIO) and will support future players (currently for example upcoming Playwright) as well.

What are some alternatives to Karma and WebdriverIO?
Jasmine
Jasmine is a Behavior Driven Development testing framework for JavaScript. It does not rely on browsers, DOM, or any JavaScript framework. Thus it's suited for websites, Node.js projects, or anywhere that JavaScript can run.
Jest
Jest provides you with multiple layers on top of Jasmine.
Mocha
Mocha is a feature-rich JavaScript test framework running on node.js and the browser, making asynchronous testing simple and fun. Mocha tests run serially, allowing for flexible and accurate reporting, while mapping uncaught exceptions to the correct test cases.
Protractor
Protractor is an end-to-end test framework for Angular and AngularJS applications. Protractor runs tests against your application running in a real browser, interacting with it as a user would.
Selenium
Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily, it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should!) also be automated as well.
