karma-commonjs

A Karma plugin that allows testing CommonJS modules in the browser. So if you are using Browserify for instance, you might find this plugin useful...

Why not just using Browserify for testing ?

Creating a single bundle means "recompiling" the bundle anytime any file changes. On big project, this can significantly slow down the development. This plugin processes only files that changed.

Installation

The easiest way is to keep karma-closure as a devDependency in your package.json.

{
  "devDependencies": {
    "karma": "~0.10",
    "karma-commonjs": "~0.1"
  }
}

Configuration

// karma.conf.js
module.exports = function(config) {
  config.set({
    frameworks: ['jasmine', 'commonjs'],
    files: [
      // your tests, sources, ...
    ],

    preprocessors: {
      '**/*.js': ['commonjs']
    }
  });
};

For an example project, check out Karma's client tests.
