Karma can't load junits plugin

Question

I'm trying to create a xml file that contains my karma test output. My configuration is as follows but I do not get an xml file + i get an error on some junits plugin. How do I install this?

'use strict';

module.exports = function(config) {

  config.set({
    autoWatch : false,
    reporters: ['progress', 'junit'],

    frameworks: ['jasmine'],

    browsers : ['PhantomJS'],

    plugins : [
        'karma-phantomjs-launcher',
        'karma-jasmine'
    ],
      junitReporter: {
        outputFile: 'test-results-karma.xml',
        suite: ''
    }
  });
};

Output in cmd

[10:50:55] Using gulpfile C:\projects\gulpfile.js
[10:50:55] Starting 'test'...
[10:50:56] Starting Karma server...
WARN [reporter]: Can not load "junit", it is not registered!
  Perhaps you are missing some plugin?

Answer 1

You have to add the plugin in your karma.conf.js. So this will look like:

 plugins : [
        'karma-phantomjs-launcher',
        'karma-jasmine',
        'karma-junit-reporter'
    ]

Try: npm install karma-junit-reporter
