Test results do not appear in browser - Grunt-karma

Question

I’m using Grunt and karma to test my project. But when I use the Grunt test command, the results do not appear in the browser nor in the command linda.

The only thing that comes up is this:

This is my karma.conf.js:`//Karma Configuration file // Generated on Mon Mar 31 2014 10:21:42 GMT-0300 (E. South America Standard Time)

module.exports = function(config) {
  config.set({

    // base path that will be used to resolve all patterns (eg. files, exclude)
    basePath: './',


    // frameworks to use
    // available frameworks: https://npmjs.org/browse/keyword/karma-adapter
    frameworks: ['jasmine','requirejs'],


// 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/angular-cookies/angular-cookies.js', 
  'app/bower_components/angular-resource/angular-resource.js', 
  'app/bower_components/angular-sanitize/angular-sanitize.js', 
  'app/bower_components/angular-mocks/angular-mocks.js',      
  'app/scripts/*.js',
  'app/scripts/**/*.js',
  'test/spec/**/*.js'
],

  plugins: [
        'karma-junit-reporter',
        'karma-chrome-launcher',
        'karma-firefox-launcher',
        'karma-jasmine',
        'karma-requirejs'
    ],    


// list of files to exclude
exclude: [

],

// web server port
port: 9876,


// enable / disable colors in the output (reporters and logs)
colors: true,

reporters: ['dots'],


// level of logging
// possible values: config.LOG_DISABLE || config.LOG_ERROR || config.LOG_WARN || config.LOG_INFO || config.LOG_DEBUG
logLevel: config.LOG_DEBUG,


// enable / disable watching file and executing tests whenever any file changes
autoWatch: false,

    browserNoActivityTimeout: 10000,


    // start these browsers
    // available browser launchers: https://npmjs.org/browse/keyword/karma-launcher
    browsers: ['Firefox'],


    // Continuous Integration mode
    // if true, Karma captures browsers, runs the tests and exits
    singleRun: false
  });
};

My test file:

describe('Controller: MainCtrl', function () {

  // load the controller's module
  beforeEach(module('AbsenteismoApp'));

  var MainCtrl,
    scope;

  // Initialize the controller and a mock scope
  beforeEach(inject(function ($controller, $rootScope) {
    scope = $rootScope.$new();
    MainCtrl = $controller('MainCtrl', {
      $scope: scope
    });
  }));

  it('deve verificar o tamanho do array expressao scope', function () {
    expect(scope.expressao.length).toBe(1);
  });
});

What will be tested:

 'use strict';

angular.module('AbsenteismoApp')
    .controller('MainCtrl',['$scope',function($scope){

        $scope.expressao = [];
  }]);

This message appears at the command prompt:

WARN [Firefox 27.0.0 (Windows 7)]: Disconnected (1 times), because no message in 10000 ms.

You are using the Require.js plugin, so it will be necessary manually initialize the tests.

If you are not going to use Require.js, I recommend that you remove references from your configuration file because the plugin changes the default behavior of Karma.

In my application, I do it as follows, using as a basis a file generated by Karma itself:

require.config({
    // Carrega todos os testes
    deps: testFiles,

    paths: ...,
    shim: ...,

    // Inicializa os testes
    callback: window.__karma__.start
});

And, in the configuration file:

files: [
    "portal/js/require/require.config.js",
    "test/modules/cic/unit-main.js",
    { pattern: "js/**/*.js", included: false },
    { pattern: "test/libs/*.js", included: false },
    { pattern: "test/unit/**/*.spec.js", included: false }
],

The Patterns who are with the included: false evening only served by the Karma HTTP server, but will not have the script tags included on the page. Thus, Require.js is in charge of these.

For Karma to close your browser you need to have Singlerun turned on. In the very description you have in the code:

// Continuous Integration mode  - Modo de integração continuo
// if true, Karma captures browsers, runs the tests and exits  - caso true o Karma abre, corre testes e fecha o browser

So switch to:

singleRun: true
