Grunt Karma unit task fail with AngularJS project

Question

I have a problem executing grunt karma:unit, the task finished but throw this:

.......
DEBUG [web-server]: serving (cached): C:/project/yo
/test/spec/services/lists.js
Firefox 32.0.0 (Windows 7): Executed 0 of 0 ERROR (0.027 secs / 0 secs)
DEBUG [karma]: Run complete, exiting.
DEBUG [launcher]: Disconnecting all browsers
DEBUG [launcher]: Process Firefox exited with code 0
DEBUG [temp-dir]: Cleaning temp dir C:\Users\developer\AppData\Local\Temp\karma-14
854612
Warning: Task "karma:unit" failed. Use --force to continue.

Aborted due to warnings.


Execution Time (2014-10-16 21:25:51 UTC)
karma:unit  4.1s  ■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■ 100%
Total 4.1s

The test directory contains the test empty, for example:

'use strict';

describe('Service: lists', function () {

});

I don't understand why the result is: Warning: Task "karma:unit" failed. Use --force to continue..

My karma.conf.js file contains:

module.exports = function(config) {
  'use strict';

  config.set({
    autoWatch: true,

    basePath: '../',

    // testing framework to use (jasmine/mocha/qunit/...)
    frameworks: ['jasmine'],

    // list of files / patterns to load in the browser
    files: [
      'app/bower_components/jquery/dist/jquery.js',
      'app/bower_components/angular/angular.js',

      'app/bower_components/bootstrap/dist/js/bootstrap.js',

      'test/spec/**/*.js'
    ],

    exclude: [],

    port: 8080,

    browsers: [
      'Firefox'
    ],

    plugins: [
      'karma-firefox-launcher',
      'karma-jasmine'
    ],

    singleRun: false,

    colors: true,

    logLevel: config.LOG_DEBUG,
  });
};

Karma needs at least 1 test to make it work/succeed. Take a look in your debug output:

Firefox 32.0.0 (Windows 7): Executed 0 of 0 ERROR (0.027 secs / 0 secs)

Once you add just one test, it will work:

Firefox 32.0.0 (Windows 7): Executed 1 of 1 SUCCESS (0.031 secs / 0 secs)

How to make console log and error's displayed in console output while running a test?

Please add the progress param into you karma configuration file.

You can read about this in documentation here: http://karma-runner.github.io/0.8/config/configuration-file.html

reporters: ['progress'],

You can try to remove : /workspace/node_modules/.karma.DELETE/ or /workspace/node_modules/karma

Then sudo npm install karma
