Karma vs Rainforest QA: What are the differences?

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; Rainforest QA: Front-end QA as a service. Rainforest gives you the reliability of a QA team and the speed of automation, without the hassle of managing a team or the pain of writing automated tests.

Karma and Rainforest QA can be primarily classified 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, Rainforest QA provides the following key features:

  • Infinitely Scalable, On-Demand QA Team
  • Cross Browser Testing
  • Regression, Functional, and Exploratory Testing

"Test Runner" is the primary reason why developers consider Karma over the competitors, whereas "Cross-browser testing" was stated as the key factor in picking Rainforest QA.

Karma is an open source tool with 10.7K GitHub stars and 1.61K GitHub forks. Here's a link to Karma's open source repository on GitHub.

      Reviews of Karma and Rainforest QA
      Review ofRainforest QARainforest QA

      As a PM with a fair amount of testing experience I've been using Rainforest QA to build up a functional test suite for our web app. Writing tests is straightforward and it's nice to then get real humans executing the tests so that you can get readable feedback when something isn't working. I'd certainly recommend giving it a try to see if it might fit your workflow.

      Automated end-to-end testing that gets our code and user experiences tested more quickly. Can be scripted. Great in a continuous delivery model.
