Karma

Alexa's Ranking: 478,453

Karma allows you to test your code on real browsers and real devices such as phones, tablets, or on a headless PhantomJS instance. With it, you can describe your tests with Mocha, Jasmine, QUnit, or write a simple adapter for any framework you like.

“Karma is essentially a tool that spawns a web server that executes source code against test code for each of the browsers connected. The results of each test against each browser are examined and displayed via the command line to the developer such that they can see which browsers and tests passed or failed.”

The configuration file can be generated using 'karma init'.

“The configuration file can be written in CoffeeScript as well. If you execute karma init with a *.coffee extension such as karma init karma.conf.coffee, it will generate a CoffeeScript file.

Of course, you can write the config file by hand or copy-paste it from another project ;-)

Karma can be extended through plugins.
