Loading AngularJS module in Jasmine test via Grunt

I am trying to write some unit tests for an AngularJS service. I want to run the unit tests from the command-line via Grunt. In an attempt to do that, I've written the following:

gruntfile.js

'use strict';
module.exports = function (grunt) {
    grunt.initConfig({
        jasmine: {
            service: {
                src: 'dist/myService.js',
                options: {
                    specs: 'test/*.js',
                    vendor: [
                        'bower_components/angularjs/angular.min.js',
                        'bower_components/angular-mocks/angular-mocks.js'
                    ]
                }
            }
        }
    });

    // load all grunt task details
    require('load-grunt-tasks')(grunt);

    grunt.registerTask('default', ['jasmine:service']);    
};

dist/myService.js

'use strict';
angular.module('myModule')
    .factory('$myService', function () {    
        return {    
            getResult: function () {
                return 3;
            }
        };
    })
;

test/serviceTests.spec.js

describe('myModule', function() {
    beforeEach(function() {
        console.log('loading module...');
        module('myModule');
    });

    describe('$myService', function () {
        it('should work', function () {
            console.log('testing');
            expect(1 + 2).toEqual(3);
        });
    });
})

When I try to run this, I get the following error:

Running "jasmine:service" (jasmine) task
Testing jasmine specs via PhantomJS

>> Error: [$injector:nomod] http://errors.angularjs.org/1.2.22/$injector/nomod?p0=myModule at
>> ..\..\..\C:\source\myModule\bower_components\angularjs\angular.min.js:20
>> ..\..\..\C:\source\myModule\bower_components\angularjs\angular.min.js:21
>> ..\..\..\C:\source\myModule\dist\myService.js
 myModule
   $myService
     - should work...
log: loading module...

log: testing
     √ should work

I know that in order to test my service, I need to inject it. However, at this time, I'm getting an error loading the module itself. For that reason, I know that I cannot inject my service. However, I do not know why the module won't load. I've confirmed that I have the correct src value.

Can anybody tell me what I'm doing wrong? Or, perhaps point me to the smallest possible example of testing a service in AngularJS (complete with Grunt, etc.)?

I just don't understand what is wrong with my approach. Thank you for your help.

When you call angular.module('myModule') (without second parameter) Angular tries to reference already existing module and cannot find it.

To declare a new module you should call angular.module('myModule', []) (with two parameters)
