Angular mock fails to inject my module dependencies

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:

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!
