Karma vs Playwright: What are the differences?

Developers describe Karma as "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. On the other hand, Playwright is detailed as "Node library to automate Chromium, Firefox and WebKit with a single API (By Microsoft)". It is a Node library to automate the Chromium, WebKit and Firefox browsers with a single API. It enables cross-browser web automation that is ever-green, capable, reliable and fast.

Karma and Playwright 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, Playwright provides the following key features:

  • Node library
  • Headless supported
  • Enables cross-browser web automation

Karma and Playwright are both open source tools. It seems that Karma with 11.1K GitHub stars and 1.64K forks on GitHub has more adoption than Playwright with 10.9K GitHub stars and 282 GitHub forks.

What are some alternatives to Karma and Playwright?
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.
