Karma vs Ghostlab: 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 Ghostlab? Test any website on various browsers and mobile devices simultaneously. It is a Mac based app that allows you to test out your responsive design across a variety of devices and browsers.
Karma and Ghostlab belong to "Browser Testing" category of the tech stack.
Some of the features offered by Karma are:
- Test on Real Devices
- Remote Control
- Testing Framework Agnostic
On the other hand, Ghostlab provides the following key features:
- Synchronized browsing
- Screenshots
- Inspect CSS on any device
Karma is an open source tool with 10.8K GitHub stars and 1.61K GitHub forks. Here's a link to Karma's open source repository on GitHub.
