Angular mock fails to inject my module dependencies

Question

I want to test an Angular controller for my application fooApp, defined as follow:

var fooApp = angular.module('fooApp', [ 'ngRoute', 'ngAnimate', 'hmTouchEvents' ]);
...

The controller, MainCtrl is defined:

"use strict";

fooApp.controller('MainCtrl', function ($scope, $rootScope, fooService) {
    ...
}

So I've tested several ways to create a test, like this one:

'use strict';

describe('MainController test', function () {

    var scope;
    var controller;

    beforeEach(function () {
            angular.mock.module('ngRoute', []);
            angular.mock.module('ngAnimate', []);
            angular.mock.module('hmTouchEvents', []);
            angular.module('cwfApp', [ 'ngRoute', 'ngAnimate', 'hmTouchEvents' ]);

            angular.mock.inject(function ($rootScope, $controller) {
                scope = $rootScope.$new();
                controller = $controller('MainCtrl', {
                    $scope: scope
                });
            });
        });

        it('should display a list', function () {
            console.log('-------------- Run Test 1 | ' + scope);
            expect(scope.currentStep).toBe(1);
        });

});

and the result:

        Error: [$injector:modulerr] http://errors.angularjs.org/1.2.16-build.64+sha.245de33/$injector/modulerr?p0=undefined&p1=Error%3A%20%5Bng%3Aareq%5D%20http%3A%2F%2Ferrors.angularjs.org%2F1.2.16-build.64%2Bsha.245de33%2Fng%2Fareq%3Fp0%3Dfn%26p1%3Dnot%2520a%2520function%252C%2520got%2520undefined%0A%20%20%20%20at%20Error%20(%3Canonymous%3E)%0A%20%20%20%20at%20http%3A%2F%2Flocalhost%3A9876%2Fbase%2Fapp%2Fbower_components%2Fangular%2Fangular.min.js%3F5961971009303638e9ad386869316e8c83f67e56%3A6%3A471%0A%20%20%20%20at%20wb%20(http%3A%2F%2Flocalhost%3A9876%2Fbase%2Fapp%2Fbower_components%2Fangular%2Fangular.min.js%3F5961971009303638e9ad386869316e8c83f67e56%3A18%3A360)%0A%20%20%20%20at%20Qa%20(http%3A%2F%2Flocalhost%3A9876%2Fbase%2Fapp%2Fbower_components%2Fangular%2Fangular.min.js%3F5961971009303638e9ad386869316e8c83f67e56%3A18%3A447)%0A%20%20%20%20at%20nc%20(http%3A%2F%2Flocalhost%3A9876%2Fbase%2Fapp%2Fbower_components%2Fangular%2Fangular.min.js%3F5961971009303638e9ad386869316e8c83f67e56%3A31%3A191)%0A%20%20%20%20at%20Object.d%20%5Bas%20invoke%5D%20(http%3A%2F%2Flocalhost%3A9876%2Fbase%2Fapp%2Fbower_components%2Fangular%2Fangular.min.js%3F5961971009303638e9ad386869316e8c83f67e56%3A33%3A176)%0A%20%20%20%20at%20http%3A%2F%2Flocalhost%3A9876%2Fbase%2Fapp%2Fbower_components%2Fangular%2Fangular.min.js%3F5961971009303638e9ad386869316e8c83f67e56%3A32%3A254%0A%20%20%20%20at%20Array.forEach%20(native)%0A%20%20%20%20at%20r%20(http%3A%2F%2Flocalhost%3A9876%2Fbase%2Fapp%2Fbower_components%2Fangular%2Fangular.min.js%3F5961971009303638e9ad386869316e8c83f67e56%3A7%3A298)%0A%20%20%20%20at%20e%20(http%3A%2F%2Flocalhost%3A9876%2Fbase%2Fapp%2Fbower_components%2Fangular%2Fangular.min.js%3F5961971009303638e9ad386869316e8c83f67e56%3A32%3A9)

I've also tested with beforeEach(angular.mock.module('cwfApp')); (instead of the first beforeEach in the previous code), but the error is almost the same.

Regarding my karma.conf.js file, I set this list of files:

    files: [
        'app/bower_components/angular/angular.min.js',
        'app/bower_components/angular-route/angular-route.min.js',
        'app/bower_components/hammerjs/hammer.min.js',
        'app/bower_components/angular-hammer/angular-hammer.js',
        'app/bower_components/angular-mocks/angular-mocks.js',

        'app/js/foo-application.js',
        'app/js/foo-controllers.js',
        'app/js/foo-services.js',
        'app/js/foo-router.js',

        'test/jasmine/*.js'
    ],

The injection seems to fail, but I don't really understand what is missing or wrong in my configuration. The stacktrace above does not give a lot of explanations...

Any idea?

I'm using Angular 1.2.8.

Edit, with the code provided by @Engineer:

beforeEach(angular.mock.module('fooApp'));

beforeEach(angular.mock.inject(function($rootScope, $controller) {
    scope = $rootScope.$new();
    controller = $controller('MainCtrl', {
        $scope: scope
    });
}));

it('should display a list', function () {
    console.log('-------------- Run Test 1 | ' + scope);
    expect(scope.currentStep).toBe(1);
});

The error is almost the same:

Answer 1

My problem was in fact due to a little mistake in karma.conf.js. Indeed, my application is defined as follow:

var fooApp = angular.module('fooApp', [ 'ngRoute', 'ngAnimate', 'hmTouchEvents' ]);

and my karma.conf.js loads the following scripts:

files: [
    'app/bower_components/angular/angular.min.js',
    'app/bower_components/angular-route/angular-route.min.js',
    'app/bower_components/hammerjs/hammer.min.js',
    'app/bower_components/angular-hammer/angular-hammer.js',
    'app/bower_components/angular-mocks/angular-mocks.js',

    'app/js/foo-application.js',
    'app/js/foo-controllers.js',
    'app/js/foo-services.js',
    'app/js/foo-router.js',

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

but the module ngAnimate was not loaded. So I just added that line:

    'app/bower_components/angular-animate/angular-animate.min.js',

and it works!

Answer 2

You are redefining fooApp module in the test.

You need to load it with Angular in the test code like this:

angular.mock.module('ngRoute', 'ngAnimate', 'hmTouchEvents', 'fooApp');

Labyrinthodont

Hello. Thanks. Sorry, it was just an error of copy / paste, due to many tests made on my code. I've edited the code test and the stack error. – Mash

You lost me... Can you create a fiddle which reproduces the problem? Can you expect(controller).toBeDefined(); ? – Labyrinthodont

I will try to create such fiddle. I'm wondering if I am not missing something regarding the fooService, required by my controller, but not mocked / created... – Mash

The parameters not passed to $controller are injected by Angular regularly, i.e. Angular injects an instance of the real controller – Labyrinthodont

Finally found the problem (cf. my answer). I forgot to add the angular-animate in karma.conf.js. – Mash

Answer 3

Try like this:

describe('MainController test', function () {
    var scope;
    var controller;

    beforeEach(angular.mock.module('fooApp'));
    beforeEach(angular.mock.inject(function($rootScope, $controller) {
        scope = $rootScope.$new();
        controller = $controller('MainCtrl', {
            $scope: scope
        });
    });
    it('should display a list', function () {
        console.log('-------------- Run Test 1 | ' + scope);
        expect(scope.currentStep).toBe(1);
    });
});

The thing, you need to understand, is if you declare some module with its dependencies(like angular.module('fooApp', [ 'ngRoute', 'ngAnimate', 'hmTouchEvents' ])), when you inject the module(fooApp) on your tests, you don't need to inject the dependency modules either.

Thanks for the information about injection of dependencies. However, trying that code didn't help me (cf. my edited post). – Mash
