Lets have a clean Karma

Setup Karma npm modules

>> npm install karma karma-jasmine karma-chrome-launcher --save-dev
// optional
// sudo npm install -g karma-cli

Initialize Karma config

>> karma init karma.config.js

In the config.js, make sure the angular files are loaded from the right path example as such

files: [
 ‘../../node_modules/angular/angular.js’,
 ‘../../node_modules/angular-mocks/angular-mocks.js’,
 ‘../../app/static/dist/static/js/*.js’,
 ‘**/*.tests.js’
 ],

Sample Test

‘use strict’;
describe(‘TopMostController’, function () {
    beforeEach(module(‘app’));
    var topMostCtrl;
    describe(‘TopMostController’, function () {
        it(‘must have animations enabled’, inject(function ($controller) {
            var $scope = {};
            topMostCtrl = $controller(‘TopMostController’, { $scope: $scope }); 
            expect(topMostCtrl.animationsEnabled).toBe(true);
         }));
    });
});

Start the karma runner:

>> karma start karma.config.js
// with --debug flag to get more information
