Controller is undefined in jasmine test

karma.config.js:
module.exports = function(config) {
config.set({
basePath: '',
frameworks: ['jasmine'],
files: [
'node_modules/angular/angular.min.js',
'node_modules/angular-mocks/angular-mocks.js',
'node_modules/angular-translate/dist/angular-translate.min.js',
'browser/javascripts/*.js',
'browser/tests/*.spec.js'
],
exclude: [],
preprocessors: {},
reporters: ['progress'],
port: 9876,
colors: true,
logLevel: config.LOG_INFO,
autoWatch: true,
browsers: ['Chrome'],
singleRun: false,
concurrency: Infinity
})
};
home.spec.js:
describe('Home Controller', function() {
beforeEach(
module('pascalprecht.translate'),
module('tradeshiftApp')
);
var $controller;
beforeEach(inject(function(_$controller_){
$controller = _$controller_;
}));
it('should exist', function(){
controller = $controller('HomeController', {
$scope: {}
});
expect(controller).not.toBe(undefined);
})
});
I am using karma-jasmine and the problem is following: my app.js file has this module and it's loading correctly:
var app = angular.module('tradeshiftApp', ['pascalprecht.translate']);
But when I try to mock my controller, which is
app.controller('HomeController', function ($scope, $req, $window, $translate, $q) {
// some code
});
I get an error, which says that HomeController is not a function. As you can see, dependencies are wired up and everything should be fine, I guess. Any tips?
Note: I've tried to inject $rootScope and get $rootScope.$new() and it's successful.

Try this:
beforeEach(function() {
angular.module('pascalprecht.translate', [])
angular.mock.module('tradeshiftApp')
}
);

So, the problem was in 'pascalprecht.translate' module. In my code I have a small dependency wired to the foregoing module, which was included in my HTML file, but not in my Karma config file. Guys, be careful and vigilant about your code :)

TypeError: $httpBackend is undefined

I am developing an angular application. I have the application running with few controllers and services. Now I wanted to start unit testing the services and controllers. But don't know what I am doing wrong, I am not able to run a test properly for a even a single service. When I try to run the test using karma using:
karma start karma.conf.js
I get following error:

I am not sure where did I go wrong. I tried to follow this stackoverflow question but was out of clue.
Any help or suggestion would be great!!
Here is my app:
'use strict';
/* App Module */
var app = angular.module('myApp', [
'ngRoute', // uri routing
'controllers', // controllers
'services', // services
'ngMock'
]);
// module controllers
var appCtrl = angular.module('controllers', []);
// module services
var appServices = angular.module('services', [ 'ngResource' ]);
Here is my service:
'use strict';
appServices.factory('MyCategoryService', ['$resource', 'REST_RESOURCE',
function ($resource, REST_RESOURCE) {
return $resource(REST_RESOURCE.PREFERENCE, {}, {
query: {
method: 'GET',
params: {},
isArray: false
}
});
}]);
Here is my Service Spec:
describe('service: MyCategoryService', function () {
var $httpBackend;
var $rootScope;
var MyCategoryService;
var REST_RESOURCE;
beforeEach(function () {
angular.mock.module('myApp');
angular.mock.inject(function ($injector) {
$httpBackend = $injector.get('$httpBackend');
$rootScope = $injector.get('$rootScope');
MyCategoryService= $injector.get('MyCategoryService');
REST_RESOURCE = $injector.get('REST_RESOURCE');
});
});
it('should send a request to MyCategoryService', function () {
//TODO
var mockdata = {
items: {
}
};
$httpBackend.expect('GET', REST_RESOURCE.PREFERENCE).respond(200, mockdata);
MyCategoryService.query(function (response) {
$rootScope.data = response.items;
});
$httpBackend.flush();
expect($rootScope.data).toEqual(mockdata);
});
});
Here is my karma.conf.js file:
module.exports = function(config) {
config.set({
// base path that will be used to resolve all patterns (eg. files, exclude)

});
};

I finally got my test running after going through some changes in some files. I don't know what the exact reason was, but I got it working with the following changes. Here's my changes below:
I removed ngMocks dependency. After changes, my app.js file looks like following.
'use strict';
/* App Module */
var app = angular.module('admintool', [ 'ngRoute', // uri routing
'controllers', // controllers
'services', // services
'angularUtils.directives.dirPagination', // pagination service
'ui.bootstrap', // angular ui bootstrap
'ui', // ui sortable
'uiSwitch', // on of switch service
'ngMessages', // for form validation
'xeditable', // for table edit
'ngCookies'
// messages
]);
// module controllers
var appCtrl = angular.module('controllers', []);
// module services
var appServices = angular.module('services', [ 'ngResource' ]);
service.js looks like:
'use strict';
//appServices.factory('PreferenceCategory', ['$resource', 'REST_RESOURCE',
angular.module('services').factory('PreferenceCategory', ['$resource', 'REST_RESOURCE',
function ($resource, REST_RESOURCE) {
return $resource(REST_RESOURCE.PREFERENCE_CATEGORY, {}, {
query: {
method: 'GET',
params: {},
isArray: false
}
});
}]);
serviceSpec.js looks like:
describe('Preference Category Service',
function() {
beforeEach(angular.mock.module("admintool"));
var httpBackend, pc;
beforeEach(inject(function($httpBackend, PreferenceCategory) {
httpBackend = $httpBackend;
pc = PreferenceCategory;
}));
afterEach(function() {
httpBackend.verifyNoOutstandingExpectation();
httpBackend.verifyNoOutstandingRequest();
});
it(
'Check GET Request',
function() {
httpBackend
.expectGET(
'http://jboss-pmadmin-tool-dev.ose-core.optum.com/pmadmin-tool/v1/preference_categories')
.respond({
username : 'test'
});
// call the function on our service instance
var response = pc.query();
httpBackend.flush();
expect(response.username).toEqual('test');
});
});
karma.conf.js file, I removed 'js/libs/*' and added individual files that are used in the app.
module.exports = function(config) {
config.set({
// base path that will be used to resolve all patterns (eg. files,
// exclude)
basePath : '../admintoolui/src/main/webapp/',

Angular 1.x, ES5/ES6 and testing with Karma

I have an angular app (with a mix of files ES5 and ES6) that i am developing tests for.
The ES6 files I'm transpiling using babel CLI with these options --modules system --module-ids.
Let's say I have samething like this:
ES5 file:
angular.module('app').controller('A', function($scope) {
...
});
ES6 file:
export class B {
constructor($scope) {
this.$scope = $scope
}
...
}
And I have a file called boot.js:
import {B} from 'controllers/B';
angular.module('app').controller('B', B);
and on my page I import the boot file (using es6-module-loader) and bootstrap the angular app:
System.import('boot').then(function() {
angular.bootstrap(document, ['app']);
});
Now, I assume I need to do something similar to the karma tests - I need to load my boot.js before running my tests.
The way I solve the problem is to call System.impot('boot') in my test files - but doesn't seems to be right:
'use strict';
System.import('boot');
describe('Controller: B', function() {
beforeEach(module('app'));
var $scope;
beforeEach(inject(function(_$rootScope_, $controller) {
scope = _$rootScope_.$new();
$controller('B', {$scope: $scope);
}));
it('...', function() {
});
});
Is there a better way to do this?

The solution I ended up finding involved using karma-systemjs.
Include all your tests files on the systemjs/files section:
systemjs: {
files: [
// TEST FILES
],
configFile: 'system.config.js',
config: {
paths: {
'angular-mocks': 'node_modules/angular-mocks/angular-mocks.js'
}
}
}
And on the tests instead of using:
System.import('boot');
Use:
'use strict';
import 'angular-mocks';
import 'angular/boot.js';
describe('Controller: B', function() {
beforeEach(module('app'));
var $scope;
beforeEach(inject(function(_$rootScope_, $controller) {
scope = _$rootScope_.$new();
$controller('B', {$scope: $scope);
}));
it('...', function() {
});
});
Hopefully this will help someone else in the future.

Unit-Testing AngularJS: Uncaught Error: [$injector:nomod] Module is not available! and ReferenceError: module is not defined when run Karma

I've a small unitTest in Jasmine run with Karma. But when i run Karma it show errors:
Uncaught Error: [$injector:nomod] Module 'material.controllers' is not
available! You either misspelled the module name or forgot to load it.
If registering a module ensure that you specify the dependencies as
the second argument.
FAILED Unit: LoginController encountered a

ReferenceError: module is not defined
Here are my source code, config Karma file and unitTest.

index.html
<body ng-app="material" ng-controller="AppController">
<ui-view></ui-view>
</body>
app.js
angular.module('material.controllers', []);
angular.module('material.services', []);
angular.module('material.directives',[]);
angular.module('material.filters',[]);
var app = angular.module('material', ['ui.router','material.directives','http-auth-interceptor','material.controllers','material.services','material.filters'])
.config(function($stateProvider, $urlRouterProvider,$locationProvider) {
$stateProvider
.state('app', {
url: "/app",
abstract: true,
templateUrl: "views/app.html"
}).state('login', {
url: "/login",
templateUrl: "views/login.html",
controller: "LoginController"
});
$urlRouterProvider.otherwise('/login');
})
loginController
angular.module('material.controllers').controller('LoginController', function($scope) {
$scope.name = "Ari";
$scope.sayHello = function() {
$scope.greeting = "Hello " + $scope.name;
}
});
helloSpec.js
describe('Unit: LoginController', function() {
// Load the module with LoginController
beforeEach(module('material.controllers'));
var ctrl, scope;
// inject the $controller and $rootScope services
// in the beforeEach block
beforeEach(inject(function($controller, $rootScope) {
// Create a new scope that's a child of the $rootScope
scope = $rootScope.$new();
// Create the controller
ctrl = $controller('LoginController', {
$scope: scope
});
}));
it('should create $scope.greeting when calling sayHello',
function() {
expect(scope.greeting).toBeUndefined();
scope.sayHello();
expect(scope.greeting).toEqual("Hello Ari");
});
})
So, i can do with that and my module's name is right?

Check the order in which the angular modules are loaded. As your listing of javascript files in karma conf, see if the module defined files are loaded first before other files that use it.
Adjust the order in this listing, are explicitly load the file where 'material.controllers' module is defined.
files: [
'/home/tanpham/Angular/Dev/libs/angular/angular.js',
'/home/tanpham/Angular/Dev/js/**/*.js',
'/home/tanpham/Angular/Dev/js/*.js',
'/home/tanpham/Angular/Test/*.js'
],

i have met this issue. and solved it.
just add ",[]" behind the module name in the module declare statement。 in this case chaged code will be :
angular.module('material.controllers',[])
.controller('LoginController', function($scope) {
$scope.name = "Ari";
$scope.sayHello = function() {
$scope.greeting = "Hello " + $scope.name;
}
});

Angularjs unit testing with Karma

Having a few issues with testing a directive - our application is trying to be modular hence the need for module.exports which exports the angular module;
module.exports = angular.module('project', [])
.config(function ($stateProvider) {
$stateProvider
.state('alive', {
url: '/college',
templateUrl: 'dashboard.html',
controller: 'CollegeCtrl',
authenticate: true
});
})
.factory('College', require('./services/college.service.js'))
.controller('CollegeCtrl', require('./dashboard/college.controller.js'))
.directive('collegeTile', require('./dashboard/tile/tile.directive.js'))
.run(function ($rootScope, SideFactory) {
SideFactory.push({
'priority': 1,
'icon': 'fa-th-large'
});
});
Directive looks like this;
<div class="thumbnail" ng-click="openProject(college._id)">
<span>{{college}}</span>
</div>
</div>
The directive spec looks like this - note, the templates loads in all the html templates;
'use strict';
describe('Directive: tile', function () {
var $compile;
var $scope;
// load the directive's module and view
beforeEach(module('ui.router'));
beforeEach(module('project'));
beforeEach(module('templates'));
// Create the SideFactory
beforeEach(module(function ($provide) {
var sideFactory = {
push: function () {
}
};
$provide.value('SideFactory', sideFactory);
}));
beforeEach(inject(function (_$compile_, _$rootScope_) {
$compile = _$compile_;
$scope = _$rootScope_.$new();
}));
it("should validate to true", function () {
expect(true).toBe(true);
});
});
I get the following error when running karma;
