How can I configure Karma to open a browser with command line arguments?

Question

I\'m using the Karma Test Runner and I\'ve configured it to use Chrome and PhantomJS like this:

browsers = [\'Chrome\', \'PhantomJS\'];

How can I configure Karma

Answer 1

One solution I found, which may not be the most elegant, is to actually modify Karma's launcher scripts for each browser. This has solved the problem.

Answer 2

Something like this should work:

// karma.conf.js
module.exports = function(config) {
  config.set({
    browsers: ['Chrome_without_security','PhantomJS_without_security'],

    // you can define custom flags
    customLaunchers: {
      Chrome_without_security: {
        base: 'Chrome',
        flags: ['--disable-web-security']
      },
      PhantomJS_without_security: {
        base: 'PhantomJS',
        flags: ['--web-security=no']
      }
    }
  });
};
