    karma-env-preprocessor

    Preprocessor which makes environment variables available to your tests.

    Installation

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

    {
      "devDependencies": {
        "karma": "~0.10",
        "karma-env-preprocessor": "~0.1"
      }
    }

    You can simple do it by:

    npm install karma-env-preprocessor --save-dev

    Configuration

    Any files you preprocess using this plugin will be affected, e.g for all JavaScript files:

    // karma.conf.js
    module.exports = function(config) {
      config.set({
        preprocessors: {
          '**/*.js': ['env']
        },
     
        envPreprocessor: [
          'PATH',
          'HOME'
        ]
      });
    };

    How does it work ?

    This preprocessor uses process.env to read the value of each environment variable specified in envPreprocessor and publishes them in the global window.__env__, so you can read these values in your tests.

    For example, the above configuration will be served as:

    window.__env__ = window.__env__ || []
    window.__env__['PATH'] = '/usr/sbin:/usr/bin:/sbin:/bin';
    window.__env__['HOME'] = '/home/jsok';
